What is Small Intestinal Bacterial Overgrowth (SIBO)? Small intestinal bacterial overgrowth (SIBO) occurs when excessive numbers of bacteria are present in the small intestine, where microbial populations are normally relatively low. Some of these bacteria may be species more commonly found in the large intestine. Because they are located higher in the digestive tract than they should be, they can ferment carbohydrates before these carbohydrates have been fully digested and absorbed. This premature fermentation produces gas and other microbial by-products, which contribute to bloating, abdominal discomfort, altered bowel habits, and other symptoms including reflux, nausea, indigestion, nutrient deficiencies, inflammation, and even fatigue and aching joints. SIBO can go un-noticed for decades and is not routinely tested for under Medicare. But SIBO isn't an obscure, fringe, or even 'naturopathic' diagnosis. SIBO was first described in 1897 and has been in medical literature ever since. Prevalence is unknown, although some authors report between 2.5 - 22% of SIBO in the general population. This discrepancy is because for some people, SIBO may be asymptomatic, or it may only 'flare' in short bursts, and symptoms are not specific. SIBO can also present alongside a systemic disease such as diabetes or cancer. Symptoms of SIBO Common digestive symptoms include abdominal pain, bloating, visible distension, excessive gas, flatulence and diarrhoea, constipation. More than two-thirds of people with SIBO report several symptoms - and I believe this is why it can go undetected for so long in some people. The type and severity of symptoms may depend on the extent of the bacterial overgrowth and the level of inflammation affecting the intestinal lining. Many people live with seemingly random digestive symptoms for years or have them dismissed as “just IBS”, particularly when standard Medicare-funded PCR stool testing does not identify a pathogen from the lower bowel. However, these tests do not assess bacterial or methanogen overgrowth in the small intestine, so a negative stool result does not make SIBO any less real. How does SIBO develop? SIBO commonly develops when food and waste move too slowly through the digestive tract. This may occur following an illness or gastrointestinal infection, such as traveller’s diarrhoea or food poisoning, which can disrupt the nerves that control intestinal movement. Motility may also slow after surgery or anaesthesia, or because of endometriosis adhesions, scar tissue or other structural changes that restrict normal movement through the bowel. Slower transit interferes with the digestive tract’s natural ability to clear bacteria and gives bacteria and archaea more time to ferment food residue and translocate around the bowel. Other contributing factors may include reduced stomach acid and the backflow of contents from the large intestine into the small intestine due to poor function of the ileocecal valve or bowel diseases. SIBO can also cause symptoms beyond the digestive system. These may include fatigue, skin changes, headaches, joint pain, low mood, anxiety and brain fog. Due to the lack of specific symptoms, the diagnosis of SIBO requires comprehensive diagnostic assessment. Can SIBO Affect Your Overall Health? When digestion and absorption are significantly affected, SIBO may contribute to weight loss or difficulty gaining weight, fatty or oily stools, vitamin and mineral deficiencies, low blood protein levels, anaemia and, in more severe cases, malnutrition. Research has found associations between SIBO and a wide range of health conditions. A literature review published in 2024 grouped these associated conditions into 12 categories: Gastrointestinal conditions: irritable bowel syndrome (IBS), non-alcoholic fatty liver disease (NAFLD), Crohn’s disease, coeliac disease, cirrhosis and pancreatitis Autoimmune conditions: including systemic sclerosis Cardiovascular conditions: heart failure, deep vein thrombosis and coronary artery disease Metabolic conditions: diabetes, obesity and high blood lipids Endocrine conditions: hypothyroidism, Graves’ disease and Hashimoto’s disease Kidney conditions: chronic and acute kidney injury Skin conditions: rosacea and psoriasis Neurological conditions: Alzheimer’s disease, Parkinson’s disease and multiple sclerosis Developmental conditions: autism spectrum disorder Mental health conditions Genetic conditions: including cystic fibrosis Gastrointestinal cancers **It is important to understand that an association does not necessarily mean SIBO caused the condition, or that the condition caused SIBO. Some of these findings may relate more broadly to changes in the gut microbiome rather than to SIBO specifically. Together, however, the research highlights the important relationship between the gut microbiome, digestive function, and overall health. The Four Microbial Overgrowth Patterns SIBO is often discussed as though it were one condition, but testing can reveal four primary microbial gas patterns: hydrogen-dominant SIBO, intestinal methanogen overgrowth, combined hydrogen and methane overgrowth, and intestinal sulfide overproduction. Identifying the dominant pattern matters because each can produce different symptoms and may require a different treatment approach. There are four primary microbial gas patterns commonly discussed in relation to SIBO. Hydrogen dominant SIBO: linked to IBS-diarrhoea type, and diarrhoea. Intestinal methanogen overgrowth (IMO): originally called methane-dominant SIBO. However, as Methanobrevibacter smithii is now classified as archaea rather than bacteria, the term IMO has been adopted. Intestinal methanogen overgrowth is associated with IBS-constipation type and manifests with symptoms like bloating, abdominal discomfort, and constipation. There is a positive association between an elevated level of methane and constipation as methane slows down intestinal transit. Moreover, methane is correlated to a severity of constipation. Hydrogen dominant SIBO and IMO frequently present concurrently; Methane-hydrogen dominant SIBO: mixed-type. Hydrogen-sulfide-SIBO: linked to IBS-D with symptoms that usually extend past the gut such as fatigue, joint pain, histamine intolerance. Hydrogen-Dominant SIBO Hydrogen-dominant SIBO occurs when excessive bacteria in the small intestine ferment carbohydrates and produce high levels of hydrogen gas. This can speed up movement through the bowel and is commonly associated with diarrhoea, bloating, gas and abdominal discomfort. Over time, disrupted digestion and nutrient absorption may contribute to deficiencies in vitamin B12, fat-soluble vitamins and minerals. In SIBO, carbohydrate fermentation primarily produces hydrogen gas which is why is it called hydrogen-dominant SIBO. Methane-Dominant SIBO: Intestinal Methanogen Overgrowth IMO Intestinal methanogen overgrowth (IMO), previously called methane-dominant SIBO, involves an overgrowth of methane-producing microorganisms called archaea, particularly Methanobrevibacter smithii in the small intestine. Archaea are biologically different from bacteria, which is why IMO is now recognised as a separate condition to classic SIBO. IMO can also cause different symptoms because methane can slow the movement of food and waste through the digestive tract, making IMO usually associated with constipation. Elevated methane levels reduce intestinal motility, leading to constipation, abdominal distension, bloating, and reflux. In IMO, archaea convert hydrogen to produce methane which can be seen on breath testing. Complete and lasting recovery can be challenging, and some people experience periods in which symptoms improve and later return. Which is why we test, and treat accordingly using a phased approach rather than using random anti-microbials and hoping for the best. Combined Hydrogen and Methane Overgrowth: Mixed-Type SIBO Combined hydrogen and methane overgrowth occurs when both gases are produced at elevated levels. Symptoms may fluctuate between diarrhoea and constipation and can include abdominal pain, bloating, reflux, nausea and persistent fatigue. Because the balance of hydrogen and methane can influence symptoms and treatment response, testing is important for developing an individualised treatment approach. Hydrogen-sulphide Dominant SIBO: intestinal sulfide overproduction (ISO) Hydrogen sulfide–dominant overgrowth, sometimes referred to as intestinal sulfide overproduction (ISO), occurs when gut microbes produce excessive hydrogen sulfide gas. Although ISO appears to be less common than hydrogen SIBO or IMO, it may occur alone or alongside either or both conditions. ISO has been associated with diarrhoea, urgency, bloating, abdominal pain and greater overall symptom severity. In one study, people with ISO alone reported the highest pain and symptom severity scores compared to SIBO and IMO. However, these findings show an association and do not yet prove that hydrogen sulfide directly causes every symptom. Hydrogen sulfide is primarily produced by gut bacteria, including sulfate-reducing bacteria. In normal amounts, it has important roles within the body, but excessive production may irritate the intestinal environment and contribute to symptoms. Even low-to-moderate levels may be relevant, with emerging research suggesting that untreated ISO could encourage the development of additional microbial overgrowth patterns and further gas production. Why Identifying the Type Matters SIBO, IMO and ISO can produce overlapping symptoms, but the microorganisms involved and gases produced are not the same. This means that a treatment that is appropriate for one pattern may be ineffective or poorly tolerated in another. Breath testing helps identify whether hydrogen, methane or hydrogen sulfide is elevated so that treatment can be tailored rather than relying on random antimicrobials and hoping for the best. Experiencing persistent bloating, altered bowel habits, abdominal discomfort, reflux, nausea, or unexplained digestive symptoms? Feel like you have tried everything but your stomach and bowels still hurt? Are you stuck in a never ending cycle of constipation, diarrhoea, and urgency? Book an appointment to discuss whether testing may be appropriate for you. Quick SIBO FAQs What are the different types of SIBO? The four main microbial gas patterns are hydrogen-dominant SIBO, methane overgrowth (IMO), combined hydrogen and methane overgrowth, and hydrogen sulfide overproduction (ISO). What is the difference between SIBO and IMO? SIBO is an overgrowth of bacteria in the small intestine, while IMO involves methane-producing archaea that may overgrow in the small or large intestine. Which type of SIBO causes constipation? Intestinal methanogen overgrowth is most commonly associated with constipation because methane can slow intestinal transit. Which type of SIBO causes diarrhoea? Hydrogen-dominant SIBO and hydrogen sulfide overproduction (IMO) are more commonly associated with diarrhoea, although symptoms vary between individuals. Can you have hydrogen and methane overgrowth together? Yes, hydrogen SIBO and methane overgrowth can occur together, producing a mixed pattern with symptoms that may alternate between diarrhoea and constipation. Does a standard stool test detect SIBO? No, a standard stool test primarily assesses the large intestine and cannot reliably identify microbial overgrowth within the small intestine. How are SIBO, IMO and ISO tested? They are usually investigated with a non-invasive breath test that measures hydrogen, methane and, where available, hydrogen sulfide after drinking a carbohydrate solution.

What is SIBO and why do we test for it? Persistent digestive symptoms such as bloating, excessive gas, abdominal pain, constipation, diarrhoea and increasing food intolerances are often attributed to IBS. However, for some people, they may be associated with excessive microbial fermentation in the upper digestive tract, this is known as SIBO (small intestinal bacterial overgrowth). SIBO was once treated as one condition with one standard protocol. We now recognise several distinct patterns: Hydrogen-dominant SIBO, involving excessive bacterial fermentation in the small intestine Intestinal methanogen overgrowth (IMO), involving methane-producing archaea in the small intestine Intestinal sulfide overproduction (ISO), an emerging term describing excessive hydrogen sulfide production Combined patterns, in which more than one gas is elevated suggesting many different species have taken over the upper digestive tract. These distinctions matter because the microorganisms produce different gases, are associated with different bowel patterns, and may require different treatment approaches. Methane is strongly associated with slower transit and constipation, while hydrogen and hydrogen sulfide patterns are more commonly associated with diarrhoea and urgency. However, symptoms alone cannot reliably identify the organisms present. A breath test provides more useful information than symptoms alone, allowing treatment to be targeted rather than relying on a generic SIBO protocol that mostly results in relapse (up to 44% of patients relapse in the first 9 months with generic treatment that only targets the infection and doesn't prioritse the landscape that enabled the infection). Due to this, in some cases, I also recommend comprehensive microbiome testing to assess the broader intestinal environment. How does a SIBO breath test work? A SIBO breath test is a simple, non-invasive test that can usually be completed at home. After following the preparation instructional guide that I give you, you drink a measured sugar solution and collect breath samples every 20 minutes over approximately three hours. When intestinal microorganisms ferment the solution, they produce gases that enter the bloodstream, travel to the lungs and are released in the breath. Measuring how these gases change over time provides information about where fermentation may be occurring and which species-type may be dominant. Results must be interpreted alongside your symptoms, bowel habits, health history and possible underlying drivers. They should not be viewed as an isolated positive or negative number. What do the different gases mean? Hydrogen Hydrogen is produced when bacteria ferment carbohydrates. A rise of at least 20 parts per million above baseline within the first 90 minutes is commonly used as one criterion for hydrogen-dominant SIBO. It is frequently associated with bloating, gas, abdominal discomfort and diarrhoea, although symptoms vary. Methane Methane is produced by archaea rather than bacteria. A level of 10 parts per million or higher at any point during the test, including at baseline, is commonly considered evidence of intestinal methanogen overgrowth. Methane is associated with slower intestinal transit, and higher levels tend to correlate with more severe constipation. Because methanogens may be present in either the small or large intestine, the correct term is intestinal methanogen overgrowth (IMO rather than methane-dominant SIBO. Hydrogen sulfide Hydrogen sulfide is produced by several groups of gut bacteria, including sulfate-reducing bacteria. Excessive production has been associated with diarrhoea, urgency, bloating and abdominal pain and may occur alone or alongside SIBO or IMO. Direct hydrogen sulfide breath testing is not currently available in Australia. Symptoms, bowel patterns and hydrogen and methane results may raise clinical suspicion of what is now know as Intestinal Sulfide Overproduction (ISO), but they cannot confirm it directly. Combined patterns More than one gas pattern may be present. Hydrogen-producing bacteria and methane-producing archaea often coexist because methane archaea use hydrogen to produce methane. Combined patterns may produce mixed or fluctuating symptoms and can influence treatment. Why is SIBO breath-test preparation so important? Correct preparation is critical for an interpretable result. The purpose of the prep diet is to reduce background fermentation so that changes following the test solution can be measured accurately. Even small deviations from the prep diet can elevate baseline gases, create an apparent false-positive result, hide the true response or make the test difficult to interpret. Preparation generally includes a temporary low-fermentation diet, an overnight fast and avoiding smoking, vigorous exercise, eating and sleeping during the collection period. Some medications and supplements may also need to be withheld where clinically appropriate. I provide you with a thorough Guide anc consultation on completing the test. If preparation cannot be completed correctly, it is usually better to postpone the test than risk receiving an unreliable result. Can a stool test detect SIBO? A standard stool test primarily examines microorganisms and markers from the large intestine. It cannot reliably determine whether excessive fermentation is occurring in the small intestine. Therefore, a negative Medicare-funded PCR stool test from the GP does not exclude SIBO or IMO. Comprehensive microbiome testing organised through Microba can provide useful information about the wider bowel environment, including microbial balance, digestive function, inflammation and potential pathogens. However, it answers a different question from a breath test. In some cases, I use both to assess the gas pattern alongside the broader gut environment. If both tests are being completed, I generally recommend collecting the microbiome sample before starting the SIBO preparation diet. What can a SIBO breath test tell us? Breath testing may identify: An early rise in hydrogen consistent with hydrogen-dominant SIBO Methane levels consistent with intestinal methanogen overgrowth Combined hydrogen and methane species overgrowth Relationships between gas production and symptoms during testing This can help explain different bowel patterns and why a previous generic treatment may not have produced lasting improvement. What can’t a SIBO breath test tell us? Breath testing cannot identify every microbial species, diagnose every cause of digestive symptoms or explain why an overgrowth developed. Results can also be influenced by preparation, intestinal transit, the chosen test solution and the gases measured. A negative result does not mean that symptoms are imagined or that no digestive problem exists. It means the test did not identify the gas pattern being assessed under those testing conditions. Why does interpretation matter? A breath-test report should not be interpreted using one number alone. I consider: Baseline gas levels When and how each gas rises Interactions between hydrogen and methane Symptoms experienced during testing Usual bowel patterns and health history Possible underlying drivers Factors affecting preparation or intestinal transit This is particularly important when results sit close to a diagnostic threshold, show elevated baseline gases, or do not fit neatly into a positive or negative category. What happens after testing? The purpose of testing is to identify the microbial pattern most likely to be contributing to symptoms and use that information to develop a targeted treatment plan. Treatment may include an initial antimicrobial phase, followed by support for digestion, intestinal motility, the intestinal lining and the broader microbiome. It is also important to investigate why the overgrowth developed. Possible drivers include food poisoning or illness, surgery or anaesthesia, endometriosis, adhesions, structural changes, reduced stomach acid, medication effects and impaired ileocecal valve function. Without addressing these factors, symptoms may improve temporarily and later return. This is why I use a phased approach involving antimicrobial treatment, repair and restoration, followed by maintenance and relapse prevention. Is SIBO breath testing right for you? Breath testing may be worth considering when persistent bloating, excessive gas, abdominal pain, constipation, diarrhoea, reflux or food reactions remain unexplained or have repeatedly been attributed to IBS. Or, when "nothing helps". Testing is not necessary for everyone. The decision should be based on your symptoms, medical history, previous investigations and whether the result is likely to meaningfully change treatment. We will investigate this in depth in our appointment.

The Modern Approach to SIBO Treatment by phenotype: Hydrogen, Methane (IMO) & Hydrogen Sulfide (ISO) The way we think about SIBO has changed For many years, SIBO (Small Intestinal Bacterial Overgrowth) was treated as one condition with one treatment. Research now recognises three distinct microbial conditions that produce different gases, different symptoms and, importantly, require different treatment approaches. These include: Condition Main Gas Typical Symptoms* Main Species* SIBO Hydrogen Bloating, pain, diarrhoea, rapid fermentation Hydrogen producers: e.g. E.coli, Klebsiella spp. Ruminococcaceae IMO (Intestinal Methanogen Overgrowth) Methane Constipation, slow gut transit Methanogens: e.g. methanobrevibacter spp. ISO (Intestinal Sulfide Overproduction) Hydrogen sulfide Diarrhoea, urgency, inflammation, rotten egg smelling farts, fructose malabsorption Sulfate-reducing bacteria: Desulfovibrio spp. *This is in no way an exhaustive list and many of my patients have different or a combination of symptoms and species found on Comprehensive Microbiome testing. One of the most important advances in the literature is that methane is not actually produced by bacteria, but by archaea, meaning IMO is biologically distinct from traditional SIBO. Likewise, hydrogen sulfide overproduction appears to have different microbes, different mechanisms and different treatment considerations from both hydrogen SIBO and IMO. This is why I prefer testing (gas breath testing and comprehensive microbiome mapping), as it allows treatment to be tailored to the dominant microbial pattern rather than applying a generic protocol (which actually just don't work in the long-term). Why does SIBO happen? The bacterial overgrowth itself is rarely the original problem. In many people, SIBO develops after something disrupts the normal protective mechanisms of the small intestine, such as: food poisoning or gastroenteritis antibiotics chronic stress impaired migrating motor complex (MMC) constipation abdominal surgery reduced stomach acid medications such as PPIs connective tissue disorders affecting gut motility hypothyroidism coeliac disease or inflammatory bowel disease The bacteria are often the consequence. If we don't address why they were able to overgrow in the first place, relapse becomes much more likely. SIBO treatment isn't one step Many people expect treatment to be: Take antimicrobials or antibiotics for four weeks → cured. Unfortunately, this is rarely how the gut works. The bacteria may improve relatively quickly, but the environment that allowed them to overgrow often takes much longer to recover. This is why my treatment plans generally move through three phases. Phase 1: Reduce the overgrowth (approximately 4–8 weeks depending on the phenotype) This is the stage most people think of when they hear "SIBO treatment." Depending on your breath test results, this may involve: herbal antimicrobials prescription antibiotics biofilm support where appropriate symptom management targeted probiotics in selected patients motility support Importantly, the treatment is chosen according to the dominant gas pattern. Hydrogen, methane and hydrogen sulfide overgrowths do not always respond to the same therapies, and newer research is increasingly moving towards phenotype-specific treatment both medically & naturopathically rather than one protocol for everyone. What about diet? One of the biggest misconceptions about SIBO is that you need to permanently eliminate large numbers of foods. I rarely recommend highly restrictive diets. While reducing fermentable carbohydrates can temporarily reduce symptoms by limiting fuel for microbial fermentation, it does not treat the underlying reason the overgrowth developed. In fact, long-term restriction may further reduce microbial diversity, making recovery more difficult. Instead, I usually use dietary modification as a temporary symptom-management tool while treatment is underway, with a clear plan to gradually reintroduce foods as the gut heals. The goal is always the most varied diet possible for you. Just like in human populations, the ocean, and the bush: diversity is the key to good health & longevity. Phase 2: Repair and restore Once the overgrowth has reduced, the real work begins. This stage often determines whether someone remains well six months later. Depending on the individual, treatment may focus on: repairing the intestinal lining restoring healthy digestive function improving stomach acid and digestive enzymes where indicated normalising bowel habits supporting bile flow rebuilding microbial diversity restoring the migrating motor complex (MMC)* improving gut motility with appropriate prokinetics reducing ongoing inflammation This is the phase that is commonly skipped, yet it is often the difference between temporary improvement and long-term recovery. *The migrating motor complex (MMC) Between meals, the small intestine performs a housekeeping cycle known as the migrating motor complex. Think of it as the gut's internal cleaning system. It sweeps leftover food particles and bacteria down into the large intestine where they can be appropriately secreted. When this system slows or stops working, bacteria have an opportunity to remain in, or translocate to, the small intestine and multiply. This is why restoring the MMC is one of the most important strategies for reducing relapse. Due to the importance of the MMC, I often introduce this support early and continue it during all phases of treatment. Phase 3: Maintain and prevent relapse The final stage is not about taking supplements forever. It is about creating a gut environment where overgrowth is less likely to return. This may include: expanding dietary diversity gradually reintroducing previously restricted foods maintaining bowel regularity supporting motility having a plan for sickness or relapse treating underlying medical conditions (e.g. thyroid, endometriosis) improving sleep, stress, and exercise maintaining a resilient microbiome My goal is always to help you become less dependent on supplements over time, not more. What about fructose malabsorption? Many people are told they have fructose malabsorption and simply avoid huge groups of plant foods for years. In some cases, that diagnosis is correct. However, fructose malabsorption can also occur secondary to SIBO. When excessive bacteria ferment fructose in the small intestine before it has a chance to be absorbed, breath testing may suggest fructose malabsorption even though the underlying problem is actually bacterial overgrowth. For some people, successfully treating the overgrowth significantly improves their tolerance to fructose-containing foods. This is another reason I prefer to identify the underlying cause rather than simply recommending lifelong dietary restriction. SIBO is often only one part of the gut-health picture Although treatment begins in the small intestine, I rarely think of SIBO as an isolated condition. Many people also have evidence of broader gastrointestinal dysfunction, including: reduced microbial diversity large bowel dysbiosis impaired short-chain fatty acid production intestinal inflammation altered bile acid metabolism fungal overgrowth parasites impaired digestive function In other words, the entire gut ecosystem may need attention. The aim is not simply to "kill bacteria". The aim is to restore a healthy, resilient microbiome that naturally resists future overgrowth.

Pregnancy is one of the most remarkable periods of growth and change a woman will experience. Yet many women find themselves navigating a constant stream of conflicting information about what to eat, which supplements to take, what tests are recommended, and what symptoms are considered normal. Rather than viewing pregnancy as a series of isolated appointments, I believe it is helpful to see it as a journey that unfolds across distinct stages. Each trimester brings unique physiological changes, nutritional requirements, screening opportunities, and preparation needs for both mother and baby. The timeline above provides an example of how naturopathic care can support you throughout pregnancy and into the postpartum period. From optimising nutrition and supporting placental development in early pregnancy, through to preparing for birth, breastfeeding, and postpartum recovery, each stage presents opportunities to support your health and wellbeing. Naturopathic care is not about replacing your medical team. It is about complementing your existing care by providing evidence-informed support for nutrition, digestion, energy, sleep, stress management, microbiome health, supplementation, and recovery. Care is tailored to your individual needs and can be adapted to support both straightforward pregnancies and those requiring additional medical monitoring. Importantly, care does not end when your baby arrives. The postpartum period is often referred to as the fourth trimester, yet recovery extends far beyond the first six weeks. Supporting maternal recovery, emotional wellbeing, nutrient replenishment, breastfeeding, and infant development can help lay strong foundations for both mother and baby. Whether you are newly pregnant, preparing for birth, or navigating life with a newborn, having a clear roadmap can help you feel more informed, supported, and confident throughout the journey.

Digestive symptoms such as bloating, reflux, abdominal pain, constipation, diarrhoea, excessive gas, food intolerances, and nutrient deficiencies can arise from many different underlying causes. While symptoms may appear similar between individuals, the drivers of those symptoms are often very different. This diagram outlines some of the factors that may contribute to digestive dysfunction and that may be considered during a comprehensive naturopathic assessment. These factors can include digestive capacity, gut motility, microbiome imbalances, infections, immune function, hormonal influences, nervous system regulation, previous surgeries, medications, and chronic health conditions. Not every factor will be relevant to every person. Rather, this list highlights the many systems that can influence gut health and demonstrates why a personalised approach is often required. By identifying and addressing the underlying contributors, naturopathic treatment may help support digestion, nutrient absorption, microbial balance, gut barrier function, and overall gastrointestinal wellbeing. The good news is that many of these factors can be supported through targeted nutrition, lifestyle changes, herbal medicine, nutritional supplementation, and collaboration with your broader healthcare team where appropriate.

For decades, Polycystic Ovary Syndrome (PCOS) has been one of the most misunderstood diagnoses in women’s health. And now, after an international consensus process involving researchers, clinicians, and patients across multiple countries, experts are recommending a new name: PMOS, or Polyendocrine Metabolic Ovarian Syndrome. At first glance, this might seem like semantics. But the name change reflects something much bigger. The term PCOS has always been misleading. Many women diagnosed with “polycystic ovaries” do not actually have ovarian cysts at all - or they do at the start and then they disappear as time goes on 🙋‍♀️. The “cysts” seen on ultrasound are usually immature follicles, not pathological cysts. Meanwhile, many women with the condition have completely normal ovarian morphology on imaging. The old name also focused heavily on the ovaries, but we understand this condition affects far more than reproduction alone. PMOS better reflects what is really happening in the body: metabolic dysfunction insulin resistance neuroendocrine disruption inflammation altered ovulation androgen excess and long-term cardiovascular and metabolic risk The new proposed name acknowledges that this is not simply a “fertility condition” or an ovarian issue. It is a whole-body endocrine and metabolic condition that can affect the brain, skin, liver, cardiovascular system, mood, appetite regulation, thyroid, and energy production. Importantly, the consensus group behind the name change also recognised that the old terminology has caused confusion, delayed diagnosis, stigma, and poor patient understanding. Many women have spent years believing they literally had “cysts on their ovaries” without ever being properly educated about the metabolic and hormonal drivers underneath their condition and symptoms. This shift also reflects a broader movement in women’s health. We are finally starting to move away from oversimplified labels and toward a more accurate understanding of female physiology. And that matters, because language shapes healthcare. When a condition is framed purely as an ovarian problem, treatment often becomes reductionistic and just about shutting off the ovaries. But when we understand PMOS as a complex neuroendocrine and metabolic condition, it opens the door to deeper conversations and clinical outcomes around insulin signalling, stress physiology, inflammation, nutrition, sleep, movement, circadian rhythm, and long-term health outcomes.

Postpartum recovery isn’t just six weeks. It is a years-long process of physiological recalibration involving hormonal shifts, immune adaptation, metabolic recovery, and brain changes that shape both mother and baby. In my last article, I outlined a new large-scale research analysing more than 1.3 million blood tests shows that many biological systems continue adapting long after birth . While some markers stabilise within months, others, particularly those linked to immunity, metabolism, and thyroid regulation can take up to two years to fully recalibrate. From the immediate postpartum period through the first 1000 days and beyond, each stage plays a critical role in maternal wellbeing and infant development. Understanding these biological changes, including the blood markers that reflect them, can help you better support your body, mind, and baby for lifelong health. Let's look at the physical, biological, attachment, and emotional changes occuring in the mother-infant dyad in the first 7 years. 6 weeks Mum’s body begins to heal, and uterine involution and bleeding is complete. Heart rate normalises to the pre-pregnant rate. Milk establishes and the maternal brain is still rewiring. It is flooded with oxytocin and prolactin while also learning to adapt to minimal sleep. Mum’s body still regulates bub’s vital systems - temperature, heart rate, respiratory rate, growth. Closeness and constant togetherness is not a ‘parenting style’ it is a biological requirement. We remain in service to our  babies as this ‘first 1000 days’ from conception to 2yo marks the most significant opportunity to establish optimum health, growth, and neurodevelopment  across the lifespan. Bub’s gestation outside of the womb ( exterogestation ) continues and they slowly start to adapt to the monumental environmental change from intrauterine to terrestrial life. They can only see approximately the distance from the nipple to mum’s face. They use the other senses deeply for the nervous system to register safety. Blood markers that stabilise early: Kidney function (creatinine, urea) Electrolytes (sodium, potassium, chloride) Early hemodynamic changes The body is reversing pregnancy adaptations such as increased blood volume and kidney filtration. Some physiological systems begin recovering quickly after birth, particularly those related to fluid balance and kidney function. 3-4 months (the end of the 'fourth trimester') For breastfeeding mothers there is a natural decline in our oxytocin which has protected our brain from the full force of tending to our babies on very little sleep while physically recovering from growing a human and birthing them....and making milk which is metabolically demanding. This is when nutrient deficiencies can take hold, depletion can set in, and resilience starts to fade. Mum's bone density may still be lower than pre-pregnancy. This coincides with massive brain growth in our babies. They need more and more fat and energy to support this growth. They wake and suckle frequently to get the fat that their brain’s need. Exterogestation continues. Bub’s vision is normalising, but they are still attaching through senses. Their brain remains vulnerable to nutrient deficiencies. Colonisation of bub's microbiome continues along with 'the first 1000 days' impacting future disease risk. Blood marker that start to stabilise: Liver markers (ALT, AST, bilirubin) Red blood cell markers (hemoglobin, hematocrit) Platelets ALP still high reflecting bone density losses This reflects recovery from pregnancy blood volume expansion and iron redistribution as well as an indication of tissue healing. 18 Months Maternal nutrient repletion is stabilising and with the right care, bone density should have returned. The cervix has regained optimal strength and capacity for holding another pregnancy*. Many Aussie women have returned to work, but sleep is still broken. An interpregnancy interval of 18–23 months may be associated with potential benefits for both mothers and infants however not all blood markers have fully recovered and many families are still breastfeeding.  Our little one’s exterogestation is coming to an end and bub’s brain begins to resemble the physical size of our mammal relatives at birth (e.g. monkeys). Their skull begins to close. They can move away from us and begin to attach by sameness. The ‘first 1000 days’ continue, and millions of neurons are forming every second - laying the architecture of bub’s brain and future health outcomes while their gut microbiome is still establishing. Mum's immune system is still recalibrating and can be seen in blood markers that are still adapting: CRP (our marker of systemic inflammation) white blood cell patterns (our immune cells) ferritin (immune + iron storage) 2 years Pregnancy-induced changes in maternal brain grey matter can still be seen at two years which may mean more efficient communication between and within brain regions.  The first 1000 days (from conception to 2yo) comes to an end along with the most rapid and sensitive time of growth and development of bub’s brain. Colonisation of bub’s gut microbiome is now complete with its own unique microbial signature which will impact and guide bub’s future immune resilience. Bub begins to realise they are not physically a part of mum and begin to attach through belonging . In terms of normalising blood markers, this is where the research shows the longest physiological arcs that are still shifting: glucose regulation (HbA1c) lipid metabolism (cholesterol, triglycerides) thyroid markers (TSH, T4) 3 years Some neuroscientists advocate that the concept of infancy should be extended out to three years old to accommodate our bub’s enormous brain growth and emotional development - including making approximately 1,000,000 neural connections a second.  Mum’s health and capacity for overall caregiving during this time greatly shapes our bub’s nervous system and trajectory towards long term health outcomes. 7 years If not adequately addressed, the symptoms of postpartum depletion and nutrient insufficiency can last for up to 7 years and develop into overt illness (such as prolapse, anaemia, or hypothyroidism). Unaddressed perinatal mood disorders can evolve into significant mental health disease. Our babies have reached a milestone in physical, spiritual, and cognitive development and have started to lose their baby-teeth.  Seven years has been a physical, philosophical, and cultural milestone age since Ancient Greek times. Rudolf Steiner emphasised the profound significance of the first seven years of life , a principle also echoed by the UN, WHO, and early childhood experts in recognising this period as crucial for lifelong health, development, and well-being. The Postpartum Timeline: Biology, Development, and Blood Markers (a summary) Postpartum Stage Maternal & Infant Physiology Maternal Blood Markers 0–6 Weeks Early healing phase. The uterus involutes, bleeding resolves, and heart rate returns to pre-pregnancy levels. Milk supply establishes while the maternal brain adapts to caregiving and sleep disruption under the influence of oxytocin and prolactin. Babies continue exterogestation, relying on close contact as Mum’s body still regulates bub’s vital systems - temperature, heart rate, respiratory rate, growth. Bub can only see approximately the distance from the nipple to mum’s face. They use the other senses for the nervous system to register safety like smell. Mum’s fluid balance stabilised as kidney function and electrolytes including sodium, potassium, and chloride normalise. These reflect the body reversing pregnancy adaptations like increased blood volume and kidney filtration. 3–4 Months (End of the “Fourth Trimester”) The end of the “fourth trimester.” Hormonal protection from high oxytocin begins to decline and maternal nutrient depletion may become apparent. Babies undergo rapid brain growth, requiring frequent feeding and high energy intake. They need more and more fat and energy to support this brain growth. They wake and suckle frequently to get the fat that their brain’s need. Exterogestation continues. Bub’s vision is normalising, but they are still attaching through senses. Their brain remains vulnerable to nutrient deficiencies. Markers reflecting tissue recovery and blood rebuilding begin stabilising, including liver markers (ALT, AST, bilirubin), red blood cell markers (haemoglobin, haematocrit), and platelets. These changes reflect recovery from pregnancy-related blood volume expansion, iron redistribution, and tissue healing. 18 Months Maternal nutrient stores are largely stabilising and the cervix regains strength for future pregnancies. Bone density should have returned in breastfeeding mothers. Many mothers have returned to work, although sleep disruption may persist. Babies approach the end of exterogestation as their brain is the size of our monkey relatives and their skull has closed. Attachment shifts from physical closeness to familiarity. Bub’s ‘first 1000 days continues’ to establish the brain’s architecture and gut microbiome. The immune system continues recalibrating, reflected in markers that may still be adapting, including C-reactive protein (CRP), white blood cell patterns, and ferritin, which reflects both immune and iron status. 2 Years The first 1000 days conclude, marking the end of the most rapid phase of brain growth and establishment of the gut microbiome. Bub recognises themselves as separate to mum and start attaching through belonging . Meanwhile, pregnancy-induced changes in maternal brain grey matter can still be seen at two years which may mean more efficient communication between and within brain regions.  Some of the longest physiological recovery arcs occur here. Markers still shifting may include glucose regulation (HbA1c), lipid metabolism (cholesterol and triglycerides), and thyroid markers (TSH and T4), reflecting gradual metabolic and endocrine recalibration. 3 Years Some neuroscientists advocate that “infancy” should be extended to three years to accommodate our bub’s enormous brain growth and emotional development.  Mum’s health and capacity for overall caregiving during this time greatly shapes our bub’s nervous system and trajectory towards long term health outcomes. By this stage most pregnancy-related laboratory markers have stabilised, but the neurological and psychological dimensions of matrescence continue evolving. 7 Years If postpartum depletion is not addressed, nutrient insufficiency and hormonal disruption can persist for years and may develop into overt illness. Children reach a major developmental milestone as they transition from early childhood toward middle childhood. Across cultures and scientific traditions, the first seven years are recognised as a foundational period shaping lifelong health and development. Long-term maternal health outcomes may reflect the cumulative effects of pregnancy, birth, and early motherhood, particularly when nutrient depletion or hormonal dysregulation remain unaddressed. So, is postpartum forever? I used to say that postpartum was forever. Until the incredible Leila from Village for Mama correctly pointed out the following : The saying “Postpartum is Forever” is often thrown around to imply that pregnancy, birth, and becoming a mother result in lifelong changes. And while motherhood undeniably leaves lasting impacts—on our identity, health, and even relationships—that’s not postpartum. That’s matrescence . Postpartum is a profound and transformative phase that begins after childbirth, bringing rapid hormonal changes, physical healing, and deep emotional shifts as you adapt to life with your baby. Matrescence is a lifelong transformation. If you're feeling depleted, struggling with brain fog, nutrient deficiencies, or emotional exhaustion, you're not alone. As a naturopath specialising in postpartum care and motherhood, I offer 1:1 appointments in Bendigo or via telehealth to help you regain energy, balance your hormones, and feel like yourself again.

What millions of blood tests reveal about pregnancy and postpartum physiology Most postpartum care systems assume recovery happens quickly. In many countries, including Australia, medical follow-up ends around six weeks after birth. But a new large-scale study suggests that postpartum biology unfolds on a much longer timeline. A landmark analysis by Korem and colleagues published in 2024 examined more than 1.3 million blood tests to map the biological changes that occur during pregnancy and postpartum. Their findings challenge the conventional view of postpartum recovery. Mapping pregnancy & postpartum with actual laboratory data The researchers analysed 48 common blood markers across pregnancy and up to two years after birth. These markers represented multiple physiological systems, including immune function, metabolism, liver and kidney function, and the thyroid. Instead of assuming that the body returns quickly to its pre-pregnancy state, the researchers asked a different question: How long does it actually take for these systems to stabilise after birth? The answer varied dramatically depending on the system being measured. Not all body systems recover at the same pace One of the most striking findings was that different physiological systems follow very different recovery timelines. Some systems appeared to stabilise within months. Others continued adapting well beyond the first year postpartum. Liver and kidney function Markers related to liver and kidney function were among the fastest to normalise. Many of these values moved back toward baseline within the first few months after birth, suggesting that core detoxification and filtration systems recover relatively quickly. Immune and inflammatory regulation Immune markers told a different story. Indicators of inflammation and immune activity continued to shift for 12–18 months postpartum, suggesting that immune recalibration extends long beyond the immediate recovery period. Thyroid regulation The thyroid axis also showed prolonged adaptation. Markers such as TSH and free T4 continued shifting well past the first year after birth, particularly in breastfeeding women. Rather than reflecting pathology, these patterns may represent ongoing hormonal adaptation during the postpartum period. Metabolic and cardiometabolic function Metabolic markers, including indicators related to glucose regulation and lipid metabolism, also followed a long recovery arc. These systems continued to remodel across the first one to two years postpartum, suggesting that metabolic recovery from pregnancy is gradual. Actual Postpartum Recovery Timeline Taken together, the data suggest that postpartum is not a brief recovery phase. Instead, it appears to be a multi-system biological transition that can extend up to two years after birth. Importantly, this transition does not occur uniformly across the body. Each physiological system follows its own timeline of adaptation. This insight may help explain why many women continue to experience changes in energy, metabolism, immune function, and thyroid regulation long after the traditional six-week postpartum milestone. A new perspective on postpartum physiology Another important implication of this research concerns laboratory interpretation. Standard reference ranges for many blood tests are based on general population data and may not account for postpartum physiology as a distinct biological state. As a result, normal postpartum adaptations could be misinterpreted as abnormal findings, or emerging dysfunction could be overlooked. Large-scale datasets such as this one offer a more nuanced view of how the body recalibrates after pregnancy. The seasonal and circadian dimension The study also identified subtle seasonal and circadian patterns in several blood markers. These findings suggest that environmental factors such as light exposure, biological rhythms, and timing may influence aspects of pregnancy and postpartum physiology. Although this observation was not the primary focus of the research, it highlights how pregnancy interacts with broader biological rhythms within the body. Rethinking postpartum care This research provides one of the most detailed physiological maps of pregnancy and postpartum recovery ever published. Rather than viewing postpartum as a short recovery period, the data suggest that it may be more accurate to see it as a prolonged phase of biological recalibration, involving the immune system, endocrine signalling, metabolism, and circadian regulation. Recognising this longer timeline may help clinicians and researchers better understand the lived experience of many women after birth. Postpartum is not simply the end of pregnancy. It is a distinct and dynamic biological phase of its own. Reference Korem, Y., Fishman, B., Radzinski, M., Maymon, R., Rothschild, D., & Segal, E. (2024). Pregnancy and postpartum dynamics revealed by millions of lab tests. Nature, 630, 371–377. https://doi.org/10.1038/s41586-024-07453-8 FAQs How long does postpartum recovery take? Research suggests that while some body systems stabilise within months, others such as immune, thyroid, and metabolic regulation may take up to two years to fully recalibrate. Why do hormones feel different long after birth? Pregnancy causes large shifts in endocrine signalling. Thyroid and metabolic markers can continue adapting for more than a year postpartum. Is the six-week postpartum check enough? The six-week visit focuses on immediate recovery. However, emerging research suggests that postpartum physiology continues evolving long after this milestone. Postpartum support in Bendigo If you are navigating the postpartum period and feel like your body is still adjusting long after birth, you are not alone. Research increasingly shows that recovery after pregnancy involves a longer biological transition affecting hormones, metabolism, and immune regulation.

The Vaginal Microbiome Part 2 Many women notice their vaginal symptoms follow a monthly pattern. This is not random. The vaginal microbiome shifts across the menstrual cycle in response to changing hormones and immune activity. In Part 1 , I explored how the vaginal microbiome functions as an ecosystem across the lifespan, and why Lactobacillus dominance is central to vaginal health. This is also why Lactobacillus-based probiotics are often used in clinical practice for recurrent thrush, BV, and microbiome disruption. However, the vaginal environment is not regulated by bacteria alone. It is supported by an innate immune system, including antimicrobial factors such as lactoferrin and glycogen, which work alongside beneficial microbes to maintain balance. Microbial populations and immune defences are highly responsive to hormonal changes across the menstrual cycle. In this article, I explore what happens in each phase of the cycle, and why symptoms can appear at predictable times each month like "why do I get thrush when I get my period?". The Vaginal Microbiome Across the Lifespan Muhleisen, 2016 How Lactobacillus Dominance Protects the Vagina A healthy vaginal microbiome is usually dominated by Lactobacillus species. These microbes act as ecological gatekeepers, preventing overgrowth of pathogenic bacteria. They do this several ways: 1. Acidification of the vaginal environment Lactobacilli ferment a substance called glycogen that is released from vaginal cells into lactic acid, which maintains an acidic vaginal pH of roughly 3.5–4.5. This acidic environment makes it difficult for many pathogens to grow. 2. Direct antimicrobial activity Many Lactobacillus strains produce antimicrobial compounds that aim to suppress organisms such as Gardnerella, E. coli, and other opportunistic microbes. 3. Competitive exclusion Beneficial bacteria physically occupy attachment sites on the vaginal surface, making it harder for pathogens to colonise. 4. Immune system modulation Lactobacilli interact with the vaginal immune system and influence inflammatory signalling, helping maintain a balanced immune response in the genital tract. Together, these mechanisms explain why our treatment always aims to restore Lactobacillus dominance and stabilise vaginal ecology. How the Vaginal Microbiome Changes During the Menstrual Cycle Menstruation Unless you experience recurring symptoms such as thrush or bacterial vaginosis around your period, you may not realise that the vaginal microbiome naturally fluctuates across the menstrual cycle under the influence of hormones and innate immunity. During menstruation, both oestrogen and progesterone are at their lowest levels. As the endometrial lining sheds, menstrual blood enters the vaginal environment. This temporarily changes the conditions within the vagina. Menstrual blood raises vaginal pH and introduces iron. Iron is an important nutrient for many microorganisms, including potentially pathogenic species. As a result, several changes commonly occur during this phase: Vaginal cells produce less glycogen, the primary fuel source of Lactobacillus species Lactobacillus numbers temporarily decline in the vagina and cervix Vaginal pH becomes less acidic, increasing dramatically from 3.5 - 7.4 Microbial diversity increases Iron becomes available as a potential fuel source for pathogenic microbes These conditions make the vaginal particularly prone to infection. When things are working optimally, the body activates protective immune mechanisms during menstruation to protect against infection and pathogen colonisation. One of these is lactoferrin, an antimicrobial protein that plays an important regulatory role by binding iron tightly. By limiting iron availability, lactoferrin helps prevent excessive growth of opportunistic bacteria during menstruation and supports the re-establishment of a healthy microbial balance. Follicular Phase As the follicular phase progresses, oestrogen levels rise. Oestrogen stimulates the vaginal epithelium to thicken and increase glycogen production. This glycogen becomes fuel for the Lactobacillus species to regrow and create lactic acid. As lactic acid production increases, vaginal pH becomes more acidic again, creating an environment that discourages pathogen growth. During this oestrogen-dominant phase, lactoferrin concentrations also increase. Lactoferrin supports vaginal defence through several mechanisms: It binds iron, limiting microbial access to this nutrient It has direct antimicrobial activity against bacteria and fungi It supports the growth of beneficial Lactobacillus microbes Together, rising oestrogen, increasing Lactobacillus populations, and higher lactoferrin activity help restore the protective microbial environment of the reproductive tract following menstruation. Ovulatory Phase Around ovulation, oestrogen reaches its peak. The vaginal epithelium is well supported, glycogen availability and Lactobacillus dominance. The microbiome during this phase is typically at its most stable and protective. Lactobacillus species produce lactic acid and antimicrobial compounds that help maintain a vaginal pH between roughly 3.5 and 4.5. Lactoferrin continues to contribute to mucosal immunity by regulating iron availability and exerting antimicrobial effects. Luteal Phase After ovulation, progesterone becomes the dominant hormone. Oestrogen levels decline relative to the follicular phase, and glycogen production in the vaginal epithelium may decrease. During this phase, lactoferrin levels tend to decline, and the vaginal immune environment becomes somewhat less protective compared with the follicular phase. The microbiome may become slightly more variable during this phase, although Lactobacillus species typically remain dominant in healthy individuals. As progesterone falls toward the end of the luteal phase, the menstrual cycle resets and the process begins again. BUT for some women this increases susceptibility to vaginal dysbiosis or irritation. And this is what we work on in clinic in Bendigo or via telehealth. Artym, 2021: The orange line shows lactoferrin following oestrogen's monthly cycle (shown in yellow) Why This Matters When women experience recurrent vaginal infections, irritation, or microbiome disruption, the underlying issue is often loss of Lactobacillus dominance combined with impaired mucosal defence. Supporting the microbiome with targeted Lactobacillus probiotics, alongside nutritional and lifestyle strategies that support mucosal immunity, can help restore the ecological balance of the vaginal environment. My clinical approach aims to: restore Lactobacillus dominance re-acidify vaginal pH support mucosal immunity via lactoferrin and lactic acid reduce pathogen overgrowth manage associated risks and diseases such as infertility and endometriosis. Can we test the vaginal microbiome? YES! If you experience recurrent thrush, bacterial vaginosis, or unexplained vaginal symptoms, it is now possible to test the vaginal microbiome directly. In clinic we can order specialised testing that analyses the microorganisms present in the vagina, including beneficial Lactobacillus species, opportunistic bacteria, yeasts, and certain viral or sexually transmitted pathogens. The test is performed using a simple vaginal swab at home and helps identify microbial imbalances that may be contributing to symptoms, allowing for a more targeted treatment plan to restore microbial balance and vaginal health.

Protein is a fundamental macronutrient required for the structure and function of every cell in the body. It provides the amino acids needed for tissue repair, muscle maintenance, hormone and enzyme production, immune function, neurotransmitter synthesis, and metabolic regulation. Adequate protein intake also supports blood glucose stability, satiety, and healthy body composition. Below I give you biochemistry breakdowns for each lifestage. This can be further calculated using your body type and your goals. For example, if you are actively trying to lose fat, you are an athlete, you are pregnant, or you suspect insulin resistance due a history of PCOS. Use my calculator below to estimate your specific needs. This intake is most effectively utilised when protein is distributed evenly across meals throughout the day rather than in one meal only in order to support protein muscle synthesis (aka the body’s growth and repair cycle). How Much Protein Do Women Need? Most women benefit from consuming 1.2 to 2 grams of protein per kilogram of body weight per day, with higher requirements during pregnancy, breastfeeding, resistance training and ageing. Protein supports muscle repair, hormone production, immune function and metabolic health across the female lifespan. Protein requirements across the Lifespan Standard: Live well Current research suggests that many active adults benefit from higher daily protein than in the current Australian Nutrition Guidelines. Particularly when supporting metabolic health, muscle preservation, hormonal balance, and recovery.  Target range: 1.6g/kg/day. Pregnancy: Building Humans Lily Nichols’ work on prenatal nutrition highlights how dramatically protein needs rise during pregnancy. By the third trimester, women may require nearly double the RDI to support foetal and placental growth, breast tissue growth, blood volume expansion, uterine and connective tissue expansion. Protein is also critical for balancing blood sugar, managing nausea, and reducing the risk of gestational diabetes. It is never recommended to "diet" during pregnancy. Target range: 1.6-1.8g/kg/day. Postpartum: Repair, Repletion and Breastmilk Postnatal depletion is a state of nutrient and tissue deficit following pregnancy and breastfeeding. Protein (along with iron, zinc, and B vitamins) is central to rebuilding connective tissue, restoring neurotransmitters, and replenishing the immune system and nutrient stores. Adequate intake supports wound healing, milk production, and the slow rebuilding of muscle changes that happened over pregnancy and the tender stages of early postpartum. *Active fat loss is not recommended during breastfeeding as endogenous toxins such as those stored in adipose tissue are fat soluble and will end up in breastmilk. Target range: 1.6-2.0g/kg/day. Perimenopause and Post-menopause: Preserving Muscle and Metabolism During perimenopause, oestrogen and progesterone fluctuations make it harder to maintain lean mass and regulate glucose. Combining progressive strength training with higher protein and an even distribution across meals helps offset these hormonal changes. Protein needs to include leucine-rich sources (e.g. eggs, fish, meat, dairy, or quality plant proteins) to activate the mTOR pathway that drives muscle protein synthesis. Target range: 1.6-2.0g/kg/day. Golden Years: Why Protein Gets Harder to Digest The older we get the weaker the pH of our stomach acid (HCl) gets. Healthy stomach acid sits around pH 1-2, creating the optimal environment to activate pepsin, the enzyme that breaks protein into smaller peptides. When HCl levels weaken and stomach pH rises (becomes less acidic) with aging, pepsin activation is impaired, meaning protein isn’t denatured or digested as efficiently. This can lead to symptoms like heaviness after meals, bloating, or undigested food in stools, and more importantly, reduced amino-acid absorption, affecting muscle maintenance, neurotransmitter production, and overall metabolic health. I certainly remember my nan putting herself on the classic "tea and toast" diet as she entered her late 80s. Supporting stomach acid through mindful eating, adequate zinc, B-vitamins, and herbal bitters can help restore protein digestion efficiency. Aim for 1.2-1.6g/kg/day.  Protein Requirements for Athletes Individuals undertaking regular resistance training, endurance exercise, or high training volumes have increased protein requirements to support muscle repair, recovery, and adaptation to training. Current sports nutrition research suggests athletes generally benefit from an intake of 1.6–2.2 grams of protein per kilogram of body weight per day , depending on training intensity, goals, and energy expenditure. At the higher end of this range, protein supports muscle protein synthesis, recovery between training sessions, preservation of lean mass during periods of calorie restriction, and improved adaptation to strength or endurance training. As with general protein recommendations, distributing protein evenly across meals throughout the day improves utilisation and supports repeated stimulation of muscle protein synthesis. Protein Needs Across the Female Lifespan Life Stage Suggested protein intake Children 1.55g/kg Reproductive Years 1.6g/kg Athletes 1.6-2.2g/kg Pregnancy 1.6-1.8g/kg Postpartum / Breastfeeding 1.6-2.0g/kg Perimenopause & Menopause 1.6-2.0g/kg Golden Years 1.2-1.6g/kg When and How to Eat Protein (and what even is 'Protein Muscle Synthesis') Muscle protein synthesis (MPS) is the physiological process through which the body repairs, maintains, and builds muscle tissue. This process occurs in cycles throughout the day (every 3 hours-ish) and is stimulated primarily by adequate dietary protein intake. The amino acid leucine plays a key regulatory role in activating this process. To effectively trigger this process and help your body take care of itself, each meal generally needs to provide approximately 2.5 grams of leucine (called the “leucine threshold” in science). In practical terms, this threshold is typically achieved by consuming around 30 to 40 grams of high-quality protein at every meal. Distributing protein evenly across the day  supports repeated stimulation of muscle protein synthesis and more effective tissue repair. For people over 40 or those with higher metabolic or training demands (see life stages below) may require slightly higher per-meal protein amounts to achieve the same anabolic response. Use the calculator above to determine your personalised daily target and divide this evenly across meals. Animal vs Plant Sources of Protein Not all protein is absorbed or utilised equally. Animal-derived proteins such as meat, eggs, dairy, and fish are highly bioavailable and contain all essential amino acids in proportions that closely match human requirements. Importantly, they also provide key nutrients that are difficult, limited, or naturally absent in plant-only diets. Vitamin B12 is found naturally only in animal foods and is essential for neurological function and methylation pathways. Long-chain omega-3 fatty acids such as DHA and EPA are most readily obtained from fish and seafood, and while small amounts of choline are present in plant foods, eggs and animal products remain the most concentrated and reliable sources. In addition, animal proteins provide highly bioavailable zinc, heme iron, iodine, selenium, creatine, and taurine. For these reasons, animal proteins tend to stimulate muscle protein synthesis more efficiently and require smaller portions to meet leucine thresholds. Plant proteins can adequately meet protein requirements when intentionally structured. Compared to animal proteins, plant sources contain different amino acid profiles and are accompanied by fibre and naturally occurring compounds such as phytates, which can modestly reduce digestibility and amino acid availability. This is overcome by having larger portion sizes and combining complementary sources such as legumes with grains, or soy products with nuts and seeds. This improves the overall amino acid balance and protein quality. Plant-based protein also confers important gastrointestinal and metabolic benefits. Legumes, whole grains, nuts, and seeds provide fermentable fibre and resistant starch that promote microbial diversity and the production of short-chain fatty acids, including butyrate. Butyrate serves as a primary fuel source for colonocytes, supports gut barrier integrity, and contributes to local immune regulation. In addition, plant foods provide antioxidants and diverse phytonutrients associated with metabolic health and long-term disease risk reduction. Debunking the Myths Women often worry that “too much protein” will harm their kidneys or “make them bulky". The evidence shows that in healthy individuals, higher protein intake does not damage the kidneys and is critical for bone, metabolic, and cognitive health. When combined with strength training and wholefoods, higher protein is likely to reduce  disease risk by improving body composition, insulin sensitivity, brain health, and mitochondrial efficiency. Protein also stimulates IGF and mTOR pathways vital for satiety repair, cognition, and mitochondrial function. Practical Takeaways for Protein intake: Start with the lower end of your target range and work up: Standard:  1.4-1.6g/kg/day Athlete: up to 2.2g/kg/day Pregnant: 1.6-1.8g/kg/day Postpartum: 1.6-2.0g/kg/day Perimenopause:  1.6-2.0g/kg/day Golden Years:  1.4-1.6g/kg/day Give yourself grace while making subtle changes to your diet, you don't need to be perfect, you need to be consistent. Active fat loss is never recommended during pregnancy or breastfeeding. Lift heavy weights at least twice a week (see other pregnancy-specific guidelines if necessary, or work with your trainer for athletic goals, or specialist for injury recovery) Walk 6000-10000 steps a day , determine your needs in this blog . Have protein with every meal and snack. You won't get bulky unless you want to (and it takes years of strict training, a specific body building coach, months of excruciating deficits (think the type of starvation that loses you your period) and bulks (that literally blow out your guts), and dangerous dehydration on photo days - unless this sounds like you, then seriously DO NOT WORRY about being "bulky". Body Building is a high-risk competitive sport; it is not the same as lifting heavy weights). Whey vs Collagen Supplements Whey protein: Whey is a complete protein and can be used as the main protein source in a smoothie, for example as a breakfast meal. Because whey is derived from directly from milk, it does have a creamy, milky taste and texture meaning it mixes best into smoothies, oats, chia pudding, yoghurt or anything creamy. It also goes well in baking however is dry so you will need to increase the liquid portion with extra eggs, milk, water, or yoghurt. It is generally very well absorbed. Be mindful of the ingredients, there are many options available but you want to look for the one with the least ingredients. Collagen: Collagen is not a complete protein source (it is missing some amino acids), so I recommend using it as a way to top up  protein intake alongside food rather than as a standalone protein source or meal replacement. It is flavourless and dissolves completely, so use it for things that you don't want to be thick or milky such as your hot drinks, herbal tea, soups, dressings. It is also great in baking. Collagen is extracted from bones and connective tissue like bone broth or slow cooked meat and dissolves similarly to gelatin. FAQs How much protein do women need per day? Most women benefit from around 1.2 to 1.6 grams of protein per kilogram of body weight per day, with higher requirements during pregnancy, breastfeeding, resistance training and ageing. Do women need protein after exercise? Yes. Protein after exercise supports muscle repair and muscle adaptation, particularly after resistance training. Is it possible to eat too little protein? Yes. Inadequate protein intake can contribute to fatigue, muscle loss, poor recovery from exercise and reduced metabolic health. What are the best protein foods for women? Eggs, yoghurt, fish, meat, legumes, tofu, nuts and seeds are nutrient-dense protein sources that support muscle, hormones and metabolic health. Looking for more?

How the Vaginal Microbiome Changes Across a Woman’s Life For over a century, research has shown that the bacteria living in the vagina play a critical role in maintaining vaginal health. When this ecosystem is balanced, it supports normal pH, tissue integrity, fertility, and protection against infections like bacterial vaginosis (BV), thrush, and UTIs. When it becomes disrupted, a state known as dysbiosis, the consequences can extend far beyond discomfort, influencing reproductive health, gynaecological outcomes, and quality of life across all stages of life. While the vaginal microbiome is important at every age, it becomes especially significant during menopause. As oestrogen levels decline, profound shifts occur within the vaginal environment. These hormonal changes alter glycogen availability (food source for favourable microbial species which relies on oestrogen), tissue thickness, and local immune signalling, creating conditions that favour a loss of protective Lactobacillus species. For many women, this biological shift manifests as vaginal dryness, burning, recurrent infections, pain with intercourse, and symptoms commonly grouped under vulvovaginal atrophy or the newer term, genitourinary syndrome of menopause . In this article, I show you how the vaginal microbiome changes across the lifespan, especially vaginal dryness after menopause and postpartum. I'll unpack how declining oestrogen reshapes the vaginal ecosystem, how these shifts relate to common symptoms, and introduce naturopathic treatments for vaginal dryness after menopause and how targeted probiotics may help restore and maintain microbial balance and vaginal health across the lifespan. Childhood and pre- puberty From Muhleisen, 2016 Prior to puberty, oestrogen production is minimal. As a result, glycogen levels within the vaginal tissue are low, microbial diversity is higher, and vaginal pH is more alkaline. During this stage, the vaginal epithelium is thin and stratified, with minimal mucus coverage, offering less structural and microbial protection. This is fine for most kiddos, but some can develop recurrent childhood UTIs, thrush, and BV and need naturopathic support - usually microbiome testing and targeted probiotic support. For everyone else, the most significant shift in the vaginal microbiome occurs at puberty. As oestrogen levels rise, glycogen content within the vaginal epithelium increases, creating an environment that supports the growth of lactic acid-producing bacteria, particularly Lactobacillus  species. This transition establishes a more acidic, resilient vaginal ecosystem that plays a central role in protection against infection and inflammation throughout the reproductive years. We are now learning that the microbiome also plays a critical role in fertility. The adult vaginal microbiome ( pre-menopausal) Adult "normal" vulvovaginal thickness and microbiome. Adapted from Muhleisen, 2016. The vaginal microbiome is dynamic and changes across a woman’s life. Age, menstrual status, and circulating oestrogen levels all shape the bacterial community of the vagina, alongside lifestyle factors such as smoking, sexual activity, and access to hygiene. In 'normal' circumstances, as a menstruating adult, the vaginal microbiome is usually dominated by beneficial Lactobacillus  species and thick, plump labia. While many bacteria naturally live in the vagina and vulva, Lactobacillus  plays a key protective role and is strongly associated with vaginal health. Lactobacillus  bacteria produce lactic acid and hydrogen peroxide, creating an acidic environment that helps prevent the overgrowth of other harmful microbes. When this balance is disrupted and Lactobacillus  levels fall, dysbiosis can occur, most commonly presenting as bacterial vaginosis (BV). BV has been linked to a range of gynaecological and reproductive health concerns across the lifespan and is very uncomfortable. Modern microbiome research shows that pre-menopausal vaginal ecosystems tend to fall into a small number of patterns, known as community state types . These patterns vary between individuals, meaning there is no single “normal” vaginal microbiome. However, higher diversity usually correlates with higher symptoms, pain, infections, and discomfort. Oestrogen plays a central role in maintaining this balance during the fertile years. Higher oestrogen supports glycogen availability, a thicker vaginal lining, and a protective mucus layer. Glycogen fuels Lactobacillus , which in turn maintain an acidic, antimicrobial environment. Together, hormones, tissue health, and beneficial bacteria form a self-reinforcing system that protects vaginal health throughout the reproductive years. The post menopause vagina, dryness, atrophy , and the microbiome Post menopausal vulvovaginal health with and without support. Adapted from Muhleisen, 2016. Menopause triggers significant changes in both the structure of the vaginal tissue and the vaginal microbiome, largely driven by falling oestrogen levels. As oestrogen declines, the vaginal lining becomes thinner, glycogen levels drop, and protective Lactobacillus  bacteria decrease. Together, these changes contribute to a cluster of symptoms known as the genitourinary syndrome of menopause (GSM), previously referred to as vulvovaginal atrophy. GSM can affect the vulva, vagina, and urinary tract. Common symptoms include vaginal dryness, burning, irritation, reduced lubrication, pain with sex, urinary urgency, discomfort with urination, and recurrent urinary tract infections. These symptoms are extremely common, with nearly half of menopausal women reporting bothersome vaginal dryness alone. While declining oestrogen is the primary driver, research increasingly shows that the vaginal microbiome plays a key role in symptom severity. Women with fewer symptoms tend to have vaginal communities dominated by Lactobacillus  species and low bacterial diversity. In contrast, women with more severe dryness, pain, and chronic infection (thrush, UTI, BV) often have reduced Lactobacillus  and higher microbial diversity of species that are not associated with good health. This shift away from a Lactobacillus-dominant microbiome is consistently associated with greater vaginal discomfort and poorer vaginal health after menopause. A note on postpartum During the postpartum period and while breastfeeding, oestrogen levels remain low, creating a vaginal environment that can closely resemble genitourinary syndrome of menopause (GSM), with a thinner vaginal lining, reduced glycogen, lower Lactobacillus  levels, and symptoms such as dryness, discomfort, pain with sex, and increased urinary irritation. There is help available. You don't need to suffer or wait until you finish breastfeeding to find relief. How to treat menopause dryness and pain. Assess the vaginal microbiome using a comprehensive, clinically relevant test where appropriate. See a sample test here. Consider the oral, gut, and vaginal microbiomes as an interconnected system rather than in isolation. Use targeted oral and topical probiotics selected for your individual symptoms and life stage. Support beneficial bacteria with appropriate “fuel” sources to encourage healthy colonisation of the vulva and vagina. Provide internal and topical herbal support to promote tissue repair, hydration, mucosal integrity and reduction in atrophy. Review environmental and lifestyle factors that influence vulvovaginal health, including soaps, laundry products, underwear fabrics, tight clothing, moisture exposure, and sweating. Review sexual and menstrual health practices, including the selection of appropriate lubricants and products that support rather than disrupt the vaginal environment. Don't accept vagina atrophy and menopause aging as "just apart of aging" If you’re navigating menopausal vaginal dryness, discomfort, or urinary changes during menopause, you don’t have to push through it or accept it as “just part of ageing.” With the right support, the vaginal microbiome and tissues can be gently restored, improving comfort, intimacy, and quality of life. If you’d like personalised guidance, I invite you to book a one-on-one consultation where we can address the root causes and create a targeted plan that works for your body and life stage. If this feels like an uncomfortable or taboo topic, please know you’re not alone, and you’re not overreacting. Vaginal pain and dryness can be deeply distressing, especially when it’s so severe that even prescribed treatments feel unbearable, or it is too painful to use the pessary prescribed by the pharmacist or GP. My clinic is a safe, respectful space to talk about these symptoms openly, and there is  gentle, effective support available for where you are at (we don't need to use pessaries, if you can't right now). We deserve to navigate this sensitive topic pain-free and with dignity.

Eat less and move more doesn't work for women If you’ve ever been told to “eat less and move more” but still struggle with stubborn fat, energy crashes, or intense cravings, you’re not alone. Women’s metabolism is far more nuanced than a simple calories-in, calories-out equation. This guide shares my clinical strategies for sustainable fat loss, eating in rhythm with your cycle (if you're still cycling), and building lean muscle. Calories in calories out fails women. Learn how hormones, cortisol, and blood sugar impact metabolism and how to work with your body : Science-Backed Alternatives to "Calories In, Calories Out" How Cortisol and Stress Impact Women's Metabolism Why Skipping Meals and Cutting Calories Can Backfire and What to Do Instead The Luteal Phase - Why You Crave Carbs Before Your Period and What to Do About It How Over-Training Can Cause Fat Around the Middle How to Exercise for Fat Loss How to Fuel for Exercise That Promotes Adaption and Fat-Loss Science-Backed Alternatives to "Calories In, Calories Out" Our bodies are deeply influenced by hormones, stress, and blood sugar regulation , meaning traditional weight loss advice (often based on research conducted on men) can actually backfire for women. The key to sustainable fat loss, stable energy, and balanced hormones  lies in understanding how cortisol, insulin, and the menstrual cycle  impact metabolism. Caveat -  There is a lot of talk on social media about cortisol, so I want to be clear that cortisol is a critical hormone. "Cortisol face" is likely a reference to a very serious endocrine disease called Cushing's. This needs to be treated by an endocrinologist and is not cured with a juice or cleanse. I think it's also important to point out that acute post-exercise cortisol is your body’s secret weapon for adaptation. What I am referring to in this blog is chronically elevated stress hormones in response to over-training and under-eating that has been sold to women as the way to "have it all" and "get toned and stay thin". How Cortisol and Stress Impact Women's Metabolism Women are naturally more sympathetically driven  than men, meaning our "fight or flight" response - and cortisol production - activates more easily (this is further increased during early motherhood and perimenopause). While cortisol is an essential daily hormone that we need to thrive, chronically high levels from stress, poor sleep, chronic dieting, over exercising overtime can: Increase blood sugar levels Disrupt insulin balance "Slow" metabolism Promote fat storage, especially visceral fat around the middle The solution? Instead of ongoing extreme restriction like 1,500 calories or skipping breakfast, prioritise strategic cycle-based nourishment  (optimal protein + healthy fats + fibre in the right amounts, at the right times) that helps stabilise blood sugar, support metabolic function, and prevent stress-induced fat storage. Why Skipping Meals and Cutting Calories Can Backfire and What to Do Instead: Many women are told that eating less and exercising more is the fastest path to weight loss. But in reality, chronically under-eating and over-training can throw our metabolism into chaos over the long term. Skipping breakfast, fasting, and overdoing fasted cardio can keep cortisol elevated for too long. While these trends are often celebrated in male-focused fitness spaces (hello 16:8 fasting), for women, regularly skipping meals, especially breakfast, has been linked to higher visceral fat, insulin resistance, and type 2 diabetes. Here’s what can happen when women undereat for too long: ↑ Cortisol = ↑ Blood sugar = ↑ Insulin = ↑ Fat storage ↓ Thyroid activity (from fasting) = Slower metabolism, lower mood, reduced fertility ↑ Hunger hormones (from starving and training) = Stronger cravings → More chance of binge eating. In clinic, I often hear women say they skip breakfast and have light lunches, only to find themselves ravenous and grazing all afternoon. Sound familiar? What to do instead: Eating in a way that regulates stress, balances blood sugar, and fuels your metabolism: Eat enough , stop restricting and signalling a deficit to your brain. Eat at least 30g of protein for breakfast . Eating protein at breakfast signals safety to our brain and we stop pumping out morning cortisol we also set the tempo for the day's blood sugar. Learn more about the benefits of eating breakfast here. Flip the fast! Instead of skipping breakfast, have an early dinner (5pm) and skip any after dinner snacks. We are less sensitive to insulin in the afternoons so we cannot process a huge dinner in the way we can process a huge breakfast. Learn about 'chrono-nutrition' here. Have at least 3-4 hours to digest dinner before going to bed . This enables optimal digestion and leaves sleep for other critical metabolic and detoxification processes. The Luteal Phase - Why You Crave Carbs Before Your Period and What to Do About It: If you happen to crave chocolate, bread, or pasta before your period? Or feel bloated around this time? It’s not a lack of willpower, it’s biology . During the luteal phase  (the second half of your cycle, after ovulation), progesterone rises and naturally increases insulin resistance and drives you to seek out more food. This is your body’s way of prioritising carbohydrates and protein in order to grow a healthy uterine lining in the case of pregnancy. We have a cycle for 35-40 years of our life! Yet, this critical biological process ( i.e. nourishing a potential baby)   is missing from the 'calories in, calories out' / 'eat less, move more' argument. What to do instead: Instead of fighting your menstrual cycle, work with it by: Choose slow-digesting, fibre-rich carbs  (e.g., sweet potatoes, quinoa, legumes) to stabilise blood sugar and clear excess hormones from the gut during the luteal phase. Chilli con carne with corn chips is my go-to. Prioritising protein and healthy fats at every meal to reduce sweet cravings and serve the uterus's demands so it stops asking you to seek out food. Adjusting workouts to lower-impact movement  (e.g., strength training, yoga) instead of high-intensity cardio to help reduce excess hunger, dehydration, and stress. How Over-Training Can Cause Fat Around the Middle: Overtraining and consistently training in a fasted state can increase cortisol, the body's primary stress and energy hormone. In women, chronically elevated cortisol levels especially without enough fuel or recovery can lead to muscle breakdown, hormone imbalances, and a shift toward storing fat around the abdomen . Paradoxically, instead of burning fat, the body may hold onto visceral fat as a survival response to stress and perceived energy scarcity if your'e pushing too hard and not eating enough. Caveat -  Remember, the best exercise is the one you enjoy! Choose activities that feel good and fit your lifestyle, whether it’s strength training, yoga, walking, or dancing. The point of this blog is to emphasize how much fuel we need, not to add stress! Consistency is key , so find what makes you feel empowered and keep moving - just fuel for the occassion.  How to Exercise for Fat Loss: BUILD MUSCLE - Lift heavy weights No, lifting weights won’t make you bulky, promise. In fact, muscle helps burn sugar, acting like a glucose sponge that improves blood sugar control and lowers your risk of insulin resistance, visceral fat, and type 2 diabetes. That’s what people really mean when they say, “fast metabolism”. Muscle needs to be considered as an endicrine organ, and the only organ we have complete control of - don't willingly let it waste away. For women in midlife, heavy resistance training is one of the best tools for staying strong, managing blood sugar, and preventing bone density loss. As the ebb and flow of oestrogen changes (around age 35-40), we begin to lose muscle and strength by 0.5-2% per year depending on how active you are. We've all heard the saying "little old lady". Lifting weights (heavy enough that you fatigue by 5–8 reps) can help slow that down. And you don’t need hours at the gym—just 2 focused sessions a week using big, compound moves is enough to make a real impact. Work with a personal trainer who understands female physiology to develop a heavy training plan. The right support will ensure that you see quick results and prevent the risk of injury. LOSE FAT - High Intensity Interval Training Sprint-style training isn’t just for athletes, it’s a game-changer for women in perimenopause and beyond.  Dr. Stacy Sims , a leading women's sport physiologist, recommends Sprint Interval Training (SIT) and H igh-Intensity Interval Training (HIIT) to support muscle retention, boost insulin sensitivity, and shift stubborn fat, especially as oestrogen levels decline with age. These sessions are short and hard. SIT  = 20 seconds of all-out sprint effort, followed by 60–90 seconds of full recovery. Repeat for 3–5 rounds. This intensity improves fat oxidation (utilising fat as fuel) and builds power by recruiting fast-twitch muscle fibres. HIIT  = 30–60 seconds of hard work with 15–30 seconds of rest between rounds. It improves cardiovascular fitness, endurance, and metabolic health. Dr. Sims highlights that SIT, in particular, is highly effective for women by helping retain lean muscle, improve metabolic flexibility, and burn fat more efficiently than steady-state cardio. Just a couple of sessions per week can deliver powerful results. Align this with your cycle: I like to do 20 seconds on the AirDyne bike followed by 90 seconds recovery, five times only twice a week during the first half of my cycle. How to Fuel for Exercise That Promotes Adaption and Fat-Loss: As you have hopefully learnt by now, female physiology thrives on fuel, especially during workouts. Here is your guide to nourished training: For weightlifting: Aim for 15g of protein before you work out. It fuels your body and boosts post-exercise oxygen consumption (i.e. calorie burn), helping to elevate your metabolism for better recovery. Here are some examples of 15g protein snacks: - 2 hard boiled eggs - 30g of almonds - 1 cup of Greek yoghurt - 1/2 a serve of a standard whey protein shake - 50g turkey slices For cardio or cardio + weights: Add around 30g of carbs to that protein before you work out. This combo helps maintain blood sugar and signals the hypothalamus that nutrition is incoming, reducing the stress response often triggered by fasting/ training. Here are some examples of 30g of complex carbs: - 1 medium banana - 1 slice sourdough - 1 apple with peanut butter - 1 cup mixed berries Always aim to have your post-workout meal within 45 minutes of training to optimise recovery and preserve lean muscle mass.
