Understanding mycotoxins and hormone disruptors, and practical ways to support your balance.
When I was exposed to mold for the first time, I had no idea how deeply it would affect me. Initially, I noticed the usual symptoms – sinus issues, headaches, and fatigue. But then the hormone symptoms started creeping in: relentless exhaustion, mood swings, and that foggy, anxious feeling that wouldn’t quit.
Looking back, those were the earliest red flags my body was sending me that something was seriously off.
What’s frustrating is that many practitioners overlook this hidden link.
Because mold illness isn’t just about breathing problems or sinus issues, it can hijack your endocrine system, messing with thyroid function, adrenal balance, and sex hormones in ways that leave you exhausted, anxious, and off-kilter.
This post is about connecting those dots. I want to show you how mycotoxins, those toxic byproducts of mold, can disrupt your hormones and, most importantly, what you can do now to start regaining your balance and energy.
How Mold Disrupts Hormones: A Quick Overview
Before we dig deeper, let’s quickly refresh how mold and its mycotoxins disrupt hormones.
When mycotoxins enter your body, they don’t just irritate your lungs or sinuses; they can interfere directly with your endocrine system, the network of glands that produce and regulate hormones. (1)
This disruption throws your hormonal balance out of whack, affecting everything from thyroid function to adrenal health and sex hormone production.
But it doesn’t stop there. Mycotoxins can also damage your mitochondria, the tiny power plants inside your cells, leaving you low on energy and less able to manage stress. (2)
When mitochondria aren’t functioning well, hormone production and regulation suffer too.
On top of that, mold exposure often triggers systemic inflammation. (3) This chronic inflammation floods your body with stress signals that further scramble hormone signals and disrupt feedback loops.
The result? Hormone imbalance that can look like fatigue, mood swings, weight gain, and more.
Understanding these root causes helps explain why mold illness often feels so overwhelming, and why addressing just one piece won’t get you back to balance.
The Hormone Systems Mycotoxins Hit the Hardest
Now that we’ve looked at how mycotoxins disrupt hormones, let’s talk about where the biggest damage happens.
Mycotoxins don’t just create vague hormonal chaos; they target specific systems in the body that regulate everything from stress response to reproductive function.
This is often where people start to feel like they’re falling apart for no obvious reason.
One month, your period’s a mess. The next, you’re dealing with anxiety and sleep issues. Soon after, your thyroid is underperforming, and your blood sugar levels are bouncing all over the place.
If that sounds familiar, you’re not alone.
These symptoms can feel disconnected, but they’re often all pointing back to the same root: mycotoxins disrupting your body’s hormonal command centers.
Here’s how that plays out in the real world.
Thyroid Disruption: Slowing the Body’s Engine
Your thyroid is highly sensitive to toxins, and mycotoxins can interfere with hormone production, conversion, and signaling.
They can block the conversion of T4 to T3, interfere with thyroid receptor sensitivity, and add inflammatory stress that suppresses overall thyroid function. (4)
Real-world impact? You might feel tired no matter how much you sleep. Cold hands and feet. Dry skin. Hair thinning. Maybe your labs are “normal,” but you know something’s off.
I remember that exact frustration during my own mold recovery – fighting to get out of bed while doctors insisted everything looked fine.
Adrenals + HPA Axis: A Constant State of Overdrive
The hypothalamic-pituitary-adrenal (HPA) axis is the communication highway that controls how your body responds to stress.
Mycotoxins can dysregulate this system, leading to irregular cortisol patterns – too high at night, too low in the morning, or flatlined entirely. (5)
This translates into that wired-but-tired feeling, poor sleep, burnout, and mood swings. I’ve been there, lying awake at 2 a.m., exhausted but buzzing, and dragging through the day like I hadn’t slept at all.
Mycotoxins essentially “confuse” your brain’s stress signals, leaving your system overreacting or shutting down.
Sex Hormones: Estrogen, Progesterone & Testosterone on a Rollercoaster
Sex hormone imbalances are incredibly common in mold-exposed patients. I’ve seen it in my own story and my practice – irregular cycles, low libido, mood swings, and hormone therapy that never quite works.
Mycotoxins are often the missing piece.
Certain mycotoxins, like zearalenone, mimic estrogen and can trigger estrogen dominance. (6) Others disrupt how your body makes hormones by damaging the mitochondria and slowing steroid hormone production. (7)
This is especially true for progesterone, which is already sensitive to stress and low energy availability.
In both men and women, mycotoxins can also interfere with testosterone and DHEA production, leading to fatigue, mood shifts, and reduced muscle tone. (8) And chronic inflammation makes things worse by blocking hormone receptors, even when your levels look “normal.”
The bottom line: if mycotoxins are clogging up the system, your hormones won’t find their rhythm, no matter how many supplements you try.
Insulin & Metabolic Function: Blood Sugar Chaos
If you’ve noticed blood sugar swings, stubborn weight gain, or fatigue after meals since your mold exposure, you’re not imagining things.
Mycotoxins can directly disrupt insulin sensitivity and glucose metabolism, setting the stage for metabolic dysfunction. (9)
Research indicates that certain mycotoxins, such as ochratoxin A and aflatoxin B1, can disrupt insulin signaling pathways and harm pancreatic beta cells, the cells responsible for producing insulin.
Over time, this increases your risk for insulin resistance, even if you’re eating well and staying active.
Add in chronic inflammation and mitochondrial dysfunction, and your cells become less efficient at using fuel.
This can lead to energy crashes, increased fat storage (especially around the midsection), and intense carb cravings, common in mold illness, but often misattributed to poor willpower or diet.
I often remind patients that mold doesn’t just affect your environment; it also affects how your body uses energy. Getting blood sugar back in balance often starts with addressing mycotoxin load, not just tweaking your macros.
When your hormones are disrupted on multiple levels, from their production to your body’s response, it’s no wonder the symptoms feel scattered and confusing.
Let’s take a closer look at how this shows up in real life.
Hormone Symptoms That Might Be Mold-Driven
Hormone symptoms often appear long before mold is ever identified as the root cause. Many of my patients (myself included) spent years chasing hormone fixes – progesterone creams, adrenal supplements, thyroid meds – without realizing their systems were reacting to something deeper.
Mycotoxins can throw off your body’s ability to regulate hormones, resulting in symptoms that shift from month to month or even day to day.
It’s one reason why mold-related hormone dysfunction can be so hard to pin down.
Here are some of the most common hormone-related signs I see in mold-exposed patients:
- Fatigue that doesn’t improve with rest
- PMS, heavy periods, or irregular cycles
- Hot flashes or night sweats (even in younger women)
- Low libido
- Weight gain, especially around the belly
- Crashes after meals or constant hunger
- Anxiety, irritability, or mood swings
- Difficulty sleeping or waking up wired at night
- Thyroid symptoms even with “normal” labs
If you’re checking several of these boxes and nothing else has worked, it may be time to look at mold more closely.
What You Can Do Right Now to Support Hormone Balance
If your hormones feel out of whack and mold is a concern, there are steps you can take right now to ease the pressure on your system and start moving in the right direction.
1. Lower Your Exposure
Reducing mycotoxin load begins with your environment.
If you suspect a moldy home or workspace, consider proper testing (ERMI is a reliable option) and take steps to limit your time in high-risk areas.
Simple shifts, like running a HEPA and carbon filter purifier or removing shoes at the door, can help lower your daily exposure.
2. Support Gentle Detox
Many mold illness patients eventually benefit from binders, liver support, bile flow nutrients, and antioxidants like glutathione, but this isn’t the place to start on your own.
Diving into heavy detox too soon can backfire if your body isn’t ready.
Instead, focus on gentle detox habits that prepare your system: stay well-hydrated, eat fiber-rich foods, and build in regular sweating through sauna sessions, gentle exercise, or Epsom salt baths.
Adding lymphatic drainage techniques, such as dry brushing or gentle massage, can also help support your body’s natural clearing pathways without overwhelming them.
These simple practices help your body gradually clear toxins without overwhelming it.
3. Balance Blood Sugar and Hormone Inputs
Blood sugar swings can make hormone imbalances worse.
Aim for regular meals that include protein, healthy fats, and slow-digesting carbohydrates to maintain steady energy and balanced hormones.
Specific nutrients are especially beneficial here: magnesium supports relaxation and insulin regulation, while B vitamins aid in energy production and the stress response. Additionally, adaptogenic herbs like ashwagandha or rhodiola can gently support your body’s ability to handle stress.
Together, these nutrients provide a foundation that helps stabilize your hormones and calm the adrenal system.
4. Care for Your Nervous System
Mold toxins can keep your body stuck in a constant “fight or flight” mode, which throws your hormone balance completely off. Helping your nervous system shift into a calmer state is key.
Simple practices, such as deep breathing exercises, gentle yoga, or spending time in nature, can signal safety to your brain and lower stress hormones.
Vagus nerve exercises, such as humming, splashing cold water on the face, or practicing slow, paced breathing, are especially effective at activating your body’s relaxation response.
Prioritizing restful sleep and setting aside quiet, screen-free time also gives your nervous system a much-needed break, helping your hormones find their natural rhythm again.
These strategies don’t replace a full mold recovery protocol, but they can lay a strong foundation. Supporting your body at this level makes everything else work better and helps you start feeling more like yourself again.
When to Get Help
If you’re still struggling with hormone symptoms despite lifestyle shifts, it’s a sign your body might need deeper mold support.
Mold-related hormone issues often won’t fully clear until the underlying mycotoxin load and immune challenges are addressed.
Don’t ignore odd or persistent symptoms just because they feel confusing or don’t fit a typical pattern. They’re your body’s way of asking for attention.
If you want a clearer roadmap to navigate the impact of mold on your hormones, my book offers practical guidance and real-world insights to help you move forward with confidence.
Connecting the Dots Between Hormones and Mycotoxins
If you’ve been chasing hormone symptoms without relief, it’s time to consider what’s underneath it all.
Mycotoxins don’t just affect your lungs or sinuses; they can throw off your thyroid, your stress response, your cycle, and your metabolism.
This is deeper than hormones “just being off.” This is your body reacting to an internal threat it hasn’t been able to escape.
You’re not imagining things. And you’re not alone.
I’ve walked this road too. And while the path can feel overwhelming at first, I want you to know: small steps matter. Every choice to reduce exposure, nourish your body, or calm your system is a step toward balance.
However, the real shift happens when we stop chasing symptoms and start targeting the root cause.
