Is It Midlife or Is It Mold?

My Story

I thought I was just adjusting to married life.

When the weight started creeping up after my husband and I got married, I told myself it made sense. I was cooking for two, eating more than I had when I was on my own, and life was fuller. What followed over the next several years felt like my body falling apart one piece at a time.

• Hypothyroidism

• Fibroids

• Insomnia

• Fatigue

• Anxiety

• Migraines

• Diziness

Every diagnosis came with its own explanation. But nobody ever connected the dots.

It took seven years to find out that the real problem was mold. We had water damage in our home that we did not recognize as a health threat, and the toxins mold produces were quietly disrupting nearly every system in my body.

My husband’s health was suffering too. In fact, it was his health struggle that uncovered my own. He had leukemia, fatigue, nerve pain, and brain fog that led us to a doctor who uncovered our health issues. (I wrote about his story and the toxin-weight connection in my last post if you missed it.)

A few years after we recovered, I developed POTS and mono while working at a medical office that also turned out to have a mold problem. Once you have lived through it, the pattern becomes much harder to miss.

I am sharing this because the symptoms I just described: weight gain, thyroid issues, fibroids, insomnia, anxiety, migraines, dizziness. Those are the things women are told are just part of midlife. And sometimes they are. But sometimes they’re mold. And the two can look remarkably alike.

If there is any chance this is you, I want you to have this information.

You can watch more about my story on the UnRX’d podcast and my blog post It’s causing your body to store fat but your doctor doesn’t know about it.

How Common Is This, Really?

Here is what most people do not realize about mold: it is not rare, and it is not just a problem for old or neglected buildings.

Research shows that 85% of buildings have a documented history of water damage, and 50% of all homes contain significant fungal growth.1

And here is the part that makes this even more complicated: about 25% of the population carries a genetic variation (HLA-DR) that makes it difficult for their body to clear mold toxins.1 .

Mold does not care if your home is new or old, dry or humid. Modern buildings are built airtight for energy efficiency, and that sealed environment is exactly where mold thrives.

You do not have to see it to be affected by it. You do not have to smell it. And you definitely do not have to know it is there.

Symptoms: Is Your Body Trying to Tell You Something?

This is where it gets important for midlife women specifically.

The symptoms of mold toxicity do not usually announce themselves as mold. They show up looking like everything else you have already been told is normal for your age.

In women, mold exposure commonly shows up as:

• Weight gain that will not respond to diet or exercise, especially around the belly

• thyroid dysfunction

• hormonal imbalances

• fibroids

• muscle loss combined with fat gain2

• insomnia

• anxiety

• depression

• chronic fatigue

• migraines

• dizziness

• racing heartbeat

• brain fog

• difficulty concentrating or finding words

• joint pain and morning stiffness

• skin rashes

• hair loss

• chronic sinus congestion or cough

• shortness of breath

• abdominal pain or bloating

Does that list look familiar? For a lot of women in midlife, it reads like a Tuesday.

In children, it looks like:

Behavioral changes, attention issues, bed-wetting that starts suddenly, sensory issues, frequent illness, and difficulty learning or retaining information.1,2 Children are often the first in a household to show symptoms because their bodies are smaller and still developing.

Medical Conditions Commonly Linked to Mold Exposure

Beyond individual symptoms, long-term mold exposure has been linked to a number of diagnosed medical conditions that are frequently treated in isolation without anyone asking what might be driving them.1,2

These include:

• autoimmune conditions

• chronic sinusitis

• Asthma, especially when it develops in adulthood

• irritable bowel syndrome

• chronic fatigue syndrome

• fibromyalgia

• anxiety disorders

• depression

• hypothyroidism

• insulin resistance and prediabetes

• neurological conditions affecting memory and cognition

Mold toxins interfere with the body's ability to produce proteins and enzymes, which affects everything from muscle repair to hormone production to how your cells generate energy.2 When those foundational processes are disrupted long enough, the body starts breaking down in ways that look like distinct diagnoses but may all share the same root cause.

This is why so many mold-affected patients end up with a growing list of diagnoses over time and a medicine cabinet full of prescriptions that manage symptoms but never resolve them. Mold illness is an emerging area of medicine, and most providers simply have not had training in it yet. That is not a criticism of your doctor. It is a gap in the curriculum that the functional medicine community is working hard to fill.

If you have several of the conditions on that list and have never had your environment evaluated, it may be worth taking a look.

What to Do If You Think It Might Be Mold

If you read through those symptoms and conditions and felt a knot in your stomach, here is what I want you to know: there are steps you can take, and having an answer, even a hard one, is always better than continuing to chase symptoms that never fully resolve.

There are two tracks to pursue:

• testing your body

• testing your environment.

Testing Your Body

A good place to start on your own is the Visual Contrast Sensitivity (VCS) test, a simple online screening tool that measures how well your eyes detect contrast. Because mold toxins affect neurological function, a failed VCS test can be an early indicator of mold exposure. The VCS has a 92% accuracy rate4 and is not a definitive diagnosis on its own, but it is not a bad place to start if you suspect mold and want an objective data point before pursuing further testing. It is also a useful tool for tracking your progress during recovery. You can take it at survivingmold.com

Dr Jill Crista also has a mold questionnaire and a helpful website

From there, a knowledgeable provider can order urine mycotoxin testing to look for evidence of mold toxins in your body. Mosaic Diagnostics is a lab that offers this testing.3 Standard bloodwork from a conventional appointment will not catch this. You need a provider who knows what to look for and what to do with the results.

Also, think beyond your home. Adults spend significant time at work, and children spend significant time at school. Any building where you or your family spend regular hours is worth considering as a potential exposure source, not just your house.

Testing Your Environment

For your home or any building you are concerned about, ERMI testing (Environmental Relative Moldiness Index) is the gold standard for identifying the types and levels of mold present.1,5 You can order a DIY ERMI test kit directly from Envirobiomics and collect the sample yourself, or have a professional collect it as part of a full inspection.11 When you order through Envirobiomics, your results will include a HERTSMI-2 score alongside the full ERMI data, giving you the clinical benchmark that matters most when mold illness is involved.

Ideally, you want both: the ERMI test for data and a physical inspection by someone who knows what they are looking for. Not every home inspector is equipped for this.

How to Find a Good Inspector

Not all mold inspectors are created equal, and choosing the wrong one can give you a false sense of security or an unnecessarily alarming report that is not interpreted correctly.

What you are looking for is someone referred to as a medically sound Indoor Environmental Professional, or IEP. This is a specialist who understands not just buildings but how indoor environments affect human health.5 They go beyond a visual check and look inside ductwork, walls, and other hidden areas where mold colonizes without ever being visible from the outside.

IEPs often use different testing methods, but when mold illness is involved the HERTSMI-2 score is particularly useful from a medical perspective. Research suggests that even the sickest patients can recover in a building when the HERTSMI-2 score is below 10, making it a meaningful benchmark for anyone dealing with mold-related health issues.1,4 A thorough IEP will incorporate this kind of testing into their process and interpret results in the context of your health symptoms.

One more important note: never hire an inspector who also does remediation. That conflict of interest means they have a financial incentive to find a problem, whether one exists or not. Your inspector and your remediator should always be two separate companies.

ISEAI at iseai.org/resources maintains a directory of qualified professionals and is the best place to start your search. They also offer a helpful resource on what to look for during the inspection process.

What Good Remediation Looks Like

If your testing and inspection confirm a mold problem, remediation is the next step. And just like with inspection, not all remediation is created equal.

The most important thing to understand is that mold must be physically removed. Fogging, spraying, or encapsulating mold does not solve the problem and can actually make things worse. 5 If a remediator leads with fogging or biocides as their primary solution, run!

Good remediation involves:

• correcting the root cause of water intrusion

• removal of damaged materials

• proper containment to prevent mold from spreading to other areas of the home during the process

• negative pressure systems that suck contaminated air out of the house

• post remediation testing, including a repeat ERMI and HERTSMI-2, and any additional tests your IEP recommends

All of this should be completed before you return to the space to confirm the environment is safe.5

ISEAI has published a thorough Mold Remediation 101 guide that walks through exactly what a proper remediation protocol looks like and the questions you should ask before hiring anyone. You can find it at iseai.org/resources.

What Recovery Looks Like

Recovery from mold illness is real, and it is possible. I am living proof of that. But it is important to go in with realistic expectations because it is not a quick fix, and it is not a straight line.

The first and most critical step is removing yourself from the exposure. Nothing else works until that happens. Your body cannot begin to clear toxins if it is still being exposed to them daily.

What most people do not know, and what I wish someone had told me, is that the nervous system needs to be addressed before almost anything else. Mold toxins are inhaled chemicals that directly trigger the limbic system and vagus nerve, putting the body into a chronic state of fight or flight that does not turn off even after the exposure ends. This is called the cell danger response, a state where the body locks into a protective mode that actively halts the healing process if it is not addressed directly.2,12 It is a physical response to a dangerous chemical, and it has to be recognized and treated as such.

Leading functional medicine practitioners recommend six to eight weeks of dedicated nervous system work before beginning any other treatments for highly sensitive patients.2 When the nervous system is stuck in survival mode, even gentle detox support can trigger a significant crash. Calming the system first is not optional. It is the foundation everything else is built on.

Tools that support nervous system recovery include:

Brain retraining programs such as the Dynamic Neural Retraining System (DNRS),6 the Gupta Program,7 and Primal Trust.8

Vagus nerve support through polyvagal strategies such as breathwork, humming, or singing. The CES Ultra device is an FDA-cleared cranial electrotherapy stimulator that applies low-frequency electrical impulses through ear electrodes to activate the vagus nerve, supporting relaxation, reducing anxiety, and improving sleep.9

Somatic / body informed therapies such as tapping (EFT), EMDR, and somatic experiencing.

Biofeedback tools like HeartMath can also help the body begin to feel safe enough to heal. 2

From there, recovery involves supporting the body's natural detox pathways, addressing the downstream effects mold has caused, whether that is thyroid dysfunction, hormonal imbalance, nervous system dysregulation, or metabolic issues, and working with a provider who understands the full picture.

Provider selection matters enormously. You want someone trained in environmentally acquired illness who follows evidence-based practices. Functional medicine practitioners, naturopathic doctors, and physicians trained in the Shoemaker Protocol are generally your best options.1,4 A provider who is not yet familiar with environmentally acquired illness will naturally treat each symptom as it presents, which is exactly what their training prepared them to do. Finding someone with additional training in environmentally acquired illness makes all the difference.

Recovery can take months to years, depending on the length and severity of exposure. But with the right support, the right environment, and the right provider, people do recover fully. I did. Twice.

How to Prevent Mold

You cannot control everything about the buildings you live and work in, but there are practical steps you can take to significantly reduce your risk.

At home, the most important things you can do are:

Keep indoor humidity below 50%. Mold thrives in moisture and struggles to grow when humidity is controlled. A simple hygrometer, available online for under twenty dollars, lets you monitor levels in your home.

Deal with leaks and water intrusion immediately. Drywall and insulation must be removed, and anything else that has been wet for more than 24-48 hours likely has fungal growth. When in doubt, consult a qualified IEP before making decisions about what to keep and what to remove.

Run exhaust fans in bathrooms and kitchens, check under sinks regularly for slow leaks, and have your HVAC system inspected and cleaned regularly, since it can be a primary distribution point for mold throughout your entire home.

If you are moving into a new home or starting a new job, it is worth asking questions about the history of water damage in the building before you commit. If possible, do an ERMI/HERTSMI test as well.

You Were Created to Thrive

If you read this entire post, something probably resonated. Maybe it was the symptom list. Maybe it was the medical conditions. Maybe it was just a quiet feeling that something has been off for a long time and nobody has been able to tell you why.

I learned the hard way. I made nearly every mistake in the book because I did not have the guidance I needed. It does not have to be that way for you.

If I had to sum up what I learned and what I most want you to walk away with, it is this:

• Mold is not something to be feared. It is something to be respected, because it has the power to damage our health in ways that conventional medicine is often not equipped to recognize or address

• If you suspect mold, test your body first, then your environment

• Before you inspect or remediate, educate yourself. The decisions you make in that process matter enormously for your health and your recovery

• If you don't know what you don’t know and you hire someone who doesn’t know what they don’t know, that’s a recipe for disaster

• Keep the humidity in your home below 50%

• Deal with leaks promptly.

Prevention is always easier than recovery.

Your body is not broken. It may be carrying a burden that has not been addressed, and there is a path forward.
