Could mould exposure be affecting your health?

This is an area I’m particularly passionate about because I see how profoundly environmental exposure can impact the way people feel — and how difficult it can be to get answers when symptoms are persistent and unexplained.

If you’ve been exposed to mould and are experiencing fatigue, brain fog, headaches, sinus or respiratory issues, digestive problems, unexplained sensitivities or simply don’t feel like yourself, it may be worth investigating what’s happening beneath the surface.

I work with clients to look at mould and environmental toxicant exposure, detoxification pathways, gut health, nutrient status and metabolic function to help piece together the bigger picture.

🌿 If you suspect mould may be affecting your health, book a consultation with me. We can look at your history, symptoms and whether testing could help us understand what’s going on.

You don’t have to keep guessing why you don’t feel well. Let’s investigate it.

🦠 Could H. pylori be contributing to your digestive symptoms, fatigue or nutrient deficiencies?

H. pylori can live in the stomach for years, sometimes without obvious symptoms, while contributing to inflammation and digestive issues, including reflux, bloating, nausea and nutrient deficiencies.

In my practice, I take a whole-body approach to gut health, with a focus on digestive and microbiome health, the gut–brain connection, nutrient status, hormonal balance and metabolic health. Where appropriate, functional testing can help us investigate what may be happening beneath the surface.

🌿 If you’re experiencing ongoing digestive symptoms or struggling to get to the root of your health concerns, book a consultation with me. Together, we can investigate what may be driving your symptoms and create a personalised plan to move your health forward.

Sometimes the key is finding out what’s actually going on.

🦠 H. pylori (Helicobacter pylori). A spiral bacterium that colonises the stomach lining and survives gastric acid by producing urease. One of the most common chronic bacterial infections worldwide, and some carriers have no symptoms at all.

🔥 Chronic gastritis. Persistent inflammation of the stomach lining that can run silently for years before anything is noticed.

🩹 Peptic ulcer disease. The leading cause of both gastric and duodenal ulcers, ahead of anti-inflammatory medication.

⚠️ Gastric cancer. Classified by the IARC as a Group 1 carcinogen. Eradication lowers that risk, and earlier is better.

🩸 Nutrient status. Linked to unexplained iron deficiency and to reduced B12 absorption where acid output has dropped.

🩺 Symptoms to watch for. Burning upper abdominal pain, often worse when hungry. Heartburn, regurgitation and bad breath. Nausea, early fullness, bloating and belching. Unexplained iron deficiency and fatigue.

🔬 Why this happens. Usually acquired in childhood and carried for life unless treated. Spread person to person via saliva, vomit and faecal-oral routes, with households often sharing one strain. Urease splits urea into ammonia to buffer the space around it, while flagella drive it into the mucus layer and adhesins anchor it to the epithelium.

🧪 Testing options. Helicobacter pylori Antigen (2010), GI-Advanced Microbiome Profile (2211), GI-Standard Microbiome Profile (2206), GI-Basic Microbiome Profile (2207).

This is such an important reminder that the gut and brain are in constant communication — and that the relationship works in BOTH directions. 🧠↔️🦠

In my practice, I see this connection come up again and again with clients experiencing things like brain fog, fatigue, poor concentration, anxiety, mood changes, digestive symptoms and difficulty getting well despite “doing all the right things”.

Rather than looking at one symptom in isolation, I take a functional, whole-body approach to understanding WHY these patterns may be occurring.

My areas of specialty include gut health and digestive function, the gut–brain connection, microbiome health, liver and detoxification pathways, nutrient deficiencies, hormonal balance and metabolic health. Where appropriate, I also use functional testing to help identify underlying patterns that may be contributing to a client’s symptoms.

The goal isn’t simply to treat the end symptom — it’s to understand what may be driving the pattern and then build a personalised plan to address it.

If you’re struggling with your digestion, energy, brain fog, mood, hormones or overall health and want to investigate what may be happening beneath the surface, I’d love to help.

Your symptoms are connected. Sometimes we just need to look at the bigger picture. ❤️

🧠 The gut-brain axis runs both ways, and the direction matters clinically. Here's what travels in each direction across four pathways.

🔌 Vagus nerve (neural). Brain to gut, it sets motility, secretion and sphincter tone, and stress withdraws vagal tone so gastric emptying slows. Gut to brain, it reports distension, nutrients and inflammation upward. Around 80% of fibres run this way.

🌙 HPA axis (endocrine). Brain to gut, cortisol shifts permeability, mucus and transit, and changes which species thrive. Gut to brain, endotoxin and mucosal inflammation raise CRH drive, keeping the axis switched on.

🛡️ Immune signalling (inflammatory). Brain to gut, neural input tunes mast cell reactivity in the gut mucosa. Gut to brain, cytokines reach the brain and drive sickness behaviour: fatigue, low mood and poor concentration.

🦠 Microbial metabolites (microbial). Brain to gut, altered transit and secretion reshape the substrate available to gut bacteria. Gut to brain, short-chain fatty acids and tryptophan metabolites feed serotonin and kynurenine pathways.

☀️ Worth remembering that roughly 95% of the body's serotonin is made in the gut, but it does not cross the blood-brain barrier. What travels is the precursor and the signal, not the neurotransmitter itself.

🎯 This is why gut testing belongs in a mood or cognition workup. When inflammation diverts tryptophan down the kynurenine pathway, or microbial function is compromised, supplementing the end product won't address what's actually limiting.

Mould related illness deserves to be taken seriously. 🍄

I’ve worked with many people struggling after exposure to damp or mouldy environments, and I’ve seen encouraging improvements when we address the whole picture. In my practice, that includes the exposure itself, sinus health, drainage support and calming an overwhelmed nervous system.

NutriPATH’s post explains the distinction between mycotoxin exposure and the body’s inflammatory response, and introduces its expanded mycotoxin panel.

🍄 One is an exposure. 🛡️ The other is how the body responds to it. 🔍 Mould toxicity and CIRS are not interchangeable, and the distinction changes how you treat.

🧪 Mould toxicity refers to the presence of mycotoxins in the body. 💧 Water-damaged buildings are the most recognised source, but exposure also occurs through contaminated food as well as occupational settings and any chronically damp environment.

🔬 This is what a urine mycotoxin test is designed to detect. ✅ It confirms exposure at the biological level, not just a symptom pattern. 🎯 Knowing exactly which mycotoxins your patient has been exposed to is key to a targeted detox rather than a generic, one-size-fits-all approach.

🛡️ CIRS (Chronic Inflammatory Response Syndrome) is an immune condition. 🧬 In genetically susceptible individuals, often those with specific HLA-DR gene variants, the immune system fails to clear biotoxins normally and remains in a persistent inflammatory state.

⚕️ CIRS has its own diagnostic criteria and treatment protocol. It isn't caused by mould exclusively, as Lyme disease and other biotoxin sources can trigger it too.

📊 The clinical distinction matters.

🔬 What it is: mould toxicity is an exposure with a measurable body burden, while CIRS is a host response to that exposure.

📏 What you measure: the toxin itself, versus the immune reaction to it.

⏳ After exposure ends: body burden falls as the patient clears it, while CIRS inflammation can persist regardless.

👥 Who it affects: anyone sufficiently exposed, versus a proposed genetically susceptible subset.

🎯 Treatment aim: remove the source and clear the toxin, versus targeting the inflammatory response.

🔗 Mould exposure can trigger CIRS, but not everyone with mould toxicity develops it. That overlap, toxin exposure plus an immune system that can't clear it, is where a lot of chronic symptoms actually originate.

🧫 Our newly expanded Mycotoxins Extensive Panel measures 31 mycotoxins, the most comprehensive mould and mycotoxin test available. 📈 It lets you confirm exposure and direct treatment accordingly.

When people come to me concerned about mould exposure, I often hear two very different stories.

One person feels wired but exhausted. They struggle to switch off, sleep poorly and may be losing weight.

Another feels heavy and depleted. Their energy is low, they crave carbohydrates and may be gaining weight.

Some people move between the two. Neither pattern tells us on its own what’s causing it. That’s why I look at the whole picture, including the person’s symptoms, health history and any dampness or water damage in their home or workplace.

For Mould Awareness Month, I’d love you to know that your experience doesn’t have to look like someone else’s to be worth exploring.

If this sounds familiar, start with the Mould Exposure Questionnaire on my website. It can help you gather your thoughts before we work through your individual situation together: meganclarke.com.au/mould-exposure-questionnaire/ (link in bio).

NutriPATH has released its new Mycotoxin Extensive Panel—one of the most comprehensive urine mycotoxin tests currently available.

The panel measures 31 mycotoxin markers across seven toxin classes, using LC-MS/MS technology with hydrolysis sample preparation and creatinine-corrected reporting.

Mycotoxin exposure may be associated with a wide range of presentations, including brain fog, fatigue, headaches, mood changes, sinus congestion, digestive symptoms and skin reactions. However, test results always need to be interpreted alongside the person’s symptoms, health history, diet and possible environmental exposures.

Mould-related illness and mycotoxin management are areas in which I specialise. I am experienced in interpreting these test results and developing a calm, individualised and staged approach to supporting the nervous system, drainage pathways, immune function, gut health and overall resilience.

🚨 NOW AVAILABLE: The most comprehensive mycotoxin test available on the market. Introducing, the Mycotoxin Extensive Panel.

🔬 This urine test measures 31 mycotoxin markers across 7 toxin classes.

⚗️ Run on LC-MS/MS with proprietary hydrolysis sample preparation and creatinine-corrected reporting, ensuring that both metabolized and original forms of mycotoxins are measured.

Built specifically for integrative and functional medicine practitioners evaluating mould and environmental toxin exposure in clinical practice.

🍄 What the panel covers:

Aflatoxins: naturally occurring mycotoxins produced by many Aspergillus species, most commonly A. flavus and A. parasiticus. Toxic and capable of producing cancer.

Gliotoxins: produced by Aspergillus fumigatus and other moulds commonly found in damp buildings. Prone to promoting immune suppression and oxidative stress with chronic exposure.

Ochratoxin A: produced by Aspergillus ochraceus and Penicillium verrucosum, and one of the most abundant food-contaminating mycotoxins in the world. Exposure occurs largely through improperly stored foods.

Trichothecenes: produced by fungi including Stachybotrys and Fusarium. They inhibit protein synthesis and are known to kill cells, making them extremely dangerous. When Stachybotrys grows in a mould-infested building, these toxins can become airborne and be inhaled.

Zearalenone: produced by several Fusarium strains including F. graminearum. An oestrogenic metabolite that can cause hormone imbalance and a range of downstream health issues.

Other mycotoxins: hundreds of moulds produce mycotoxins toxic to humans and pets. These often present as nondescript symptoms, leading to cycles of misdiagnosis and an inability to reach the root cause.

🩺 Common presentations worth testing:
Brain fog, chronic fatigue, depression and mood disorders, digestive issues, headaches and migraines, sinus congestion, and skin conditions such as dermatitis and rashes, and many more.

🧩 These symptoms rarely point anywhere on their own, which is exactly why measuring exposure directly changes the clinical picture.

Running a Dutch Test is a great way to establish what is going on with your hormones.

🧭 Female hormone complaints rarely arrive labelled. The same presentation of fatigue, mood change and cycle disruption can sit in four very different places. Here's what each pattern tends to look like.

⚡ Androgen excess. Too much androgen, or too little binding it. Trouble conceiving, cycles longer than 35 days or skipping months entirely, facial or chest hair growth, thinning at the temples, deep cystic acne along the jaw, dark velvety patches at the neck, and crashing after carb-heavy meals.

🌸 Oestrogen clearance. How she clears it, not just how much she makes. Heavy periods with clotting, PMS starting two weeks out, cyclical mood dips, premenstrual fluid retention, migraines that track the cycle, breast tenderness for days beforehand, weight settling on hips and thighs, and a history of fibroids or endometriosis.

🌙 Progesterone insufficiency. The luteal phase is where this shows. A luteal phase shorter than 11 days, spotting for days before the bleed, low mood confined to the second half, anxiety climbing after ovulation, sleep breaking down post-ovulation, night sweats late in the cycle, cycles shortening then turning erratic, and a history of early pregnancy loss.

☀️ Cortisol rhythm. The shape of the curve, not the single number. Exhausted at 3pm and wired at 10pm, waking unrefreshed after eight hours, unable to start the day without coffee, craving salt, dizzy on standing, snapping at small things, slower exercise recovery, and getting sick after busy periods.

🔬 Note how much overlap sits between them. Fatigue, low mood and disrupted sleep appear in nearly every column, which is precisely why symptom picture alone can't direct treatment. Comprehensive hormone testing tells you which mechanism you're actually working with.
