Our Approach to Mold Toxicity

A Root Cause of Chronic Illness You Cannot Ignore

At the Marty Ross MD Clinic in Seattle, WA, we see people every day who have been told their labs are “normal,” yet they continue to struggle with fatigue, brain fog, pain, insomnia, and a long list of unexplained symptoms.

We want you to know: we see you, and it’s not in your head.

One of the most overlooked drivers of these symptoms is mold toxin illness.

Mold toxicity is a leading cause of symptoms in chronic fatigue syndrome, fibromyalgia, and in people who are not improving despite appropriate treatment for Lyme disease and other tick-borne infections. In fact, in some individuals, mold toxicity is the primary reason they are ill, not infection or other previously diagnosed conditions.

What Is Mold Toxicity?

Mold toxicity develops when your body cannot effectively remove mycotoxins, poisonous substances produced by molds found in water-damaged buildings.

In most people, the immune system tags these toxins and removes them efficiently. But for 25% of the population, this system fails. Instead of being eliminated, toxins recirculate from the liver into the intestines and are reabsorbed again back into the bloodstream.

This ongoing recycling of toxins leads to a chronic inflammatory response driven by cytokines produced in white blood cells.

Cytokine excess causes fatigue, pain, cognitive dysfunction, hormone dysregulation, and sleep disturbance. These inflammatory chemicals are responsible for many of the symptoms people associate with Lyme disease, mold toxicity, fibromyalgia, and chronic fatigue syndrome.

This is why mold toxicity can look identical to Lyme disease, and why only treating infections can fail.

Mold Toxicity Blocks Recovery from Lyme Disease

In my experience, mold toxin illness can act as a “toxin trap” perpetuating disease.

As described in my approach to chronic Lyme disease, we must look beyond infections and identify root causes. Mold exposure is one of the most important of these. In some cases, addressing mold toxicity alone is enough to restore health, even when testing shows a presence of tick-borne infections.

How I Diagnose Mold Toxicity

Diagnosis begins with a careful clinical history. I look for:

• Exposure to water-damaged environments

• Onset of symptoms after moving into a new home or workplace

• Chronic symptoms that resemble Lyme disease or chronic fatigue

• Poor response to antimicrobial therapies

Testing can support the diagnosis, but no test is perfect.

Screening Test

The Visual Contrast Sensitivity (VCS) test is a useful first step. People with mold toxicity often have difficulty distinguishing contrast in black and white due to the neurological effects of toxins.

Direct Testing

The most useful test is a urine mycotoxin test from RealTime Labs and Mosaic Diagnostics which detects toxins currently in the body. To provoke release of toxins stored in the body, we may recommend a hot bath or sauna the evening before the urine collection. However, this test can miss cases if the body is not effectively excreting toxins via the kidneys.

Indirect Testing

We do not recommend indirect tests that do not directly measure toxin levels. Mycotoxin antibody tests from MyMycoLab, genetic markers, and inflammatory biomarkers can provide clues, but they do not prove the presence of mold toxins. Because of these limitations, diagnosis is often a combination of history, symptoms, and selective testing.

The Roadmap to Recovery

We apply a systems-based framework to mold toxicity. Recovery is not about any one treatment; it’s about restoring balance across the entire body.

1. Stabilizing the Internal Environment: Lifestyle & Support

Recovery cannot happen in a body that is constantly in “crisis mode.” We begin by addressing the foundational elements to restore balance, optimize function, and decrease inflammation.

• Sleep: Mold toxicity triggers inflammatory cytokines that disrupt sleep centers in the brain. Without 7–9 hours of restorative sleep, pain worsens and cytokines increase. The first step to correct sleep starts with good sleep hygiene and may include wearables (for more information, see The Ultimate Sleep Guide for Lyme, Tick-borne Diseases, and Mold Toxicity). At times, we use targeted supplements like L-Theanine or, when necessary, prescription options like Trazodone to restore this vital function.

• Diet & Microbiome: We emphasize a plant-forward, anti-inflammatory diet. This isn’t just about nutrition, it’s about protecting your “second brain,” the intestinal microbiome. We may recommend polyphenols, prebiotic fibers, and spore-forming probiotics to maintain a healthy gut, which decreases inflammation and improves the function of all body systems.

• Cytokine Inflammation Control: While cytokines are meant to fight toxicity, in mold toxin illness, they cause: brain fog, insomnia, pain, fatigue, and even muscle wasting. We use liposomal curcumin and other antioxidants to “turn down the volume” on this inflammation.

2. Addressing System Failures

• Hormonal & Mitochondrial Support: Chronic illness is an energy thief. We use adaptogens like Ashwagandha to support adrenal and thyroid function. We recommend essential micronutrients to repair the “mitochondrial power plants” in your cells. At times we may even recommend mitochondria resuscitation.

• Liver Detoxification: We support the liver, the master of detox, using liposomal glutathione to remove neurotoxins and repair damaged brain tissue.

3. Addressing Mold Toxicity

• Binders for Mold Toxins:The hallmark of mold illness is toxin recirculation. To break this cycle, we use binders: substances that attach to toxins in the intestines and carry them out of the body.

  Common options include:

  • Cholestyramine (prescription binder)

  • Activated charcoal

  • Bentonite clay

  • Soluble fibers like pectin

  • broad-spectrum combination binder products made up of charcoal, bentonite clay, humic acid, fulvic acid, and even pectin

  These binders prevent toxins from being reabsorbed and gradually lower the total toxic burden.

  It’s important to understand that symptoms may initially worsen. As toxins are mobilized, cytokine levels can temporarily rise. Managing inflammation during this phase is essential.

• Targeting Mold Colonization:In some individuals, mold is not just an exposure, rather it becomes a persistent infection in the body. Research and clinical experience suggest that mold can colonize the sinus passages and intestines, serving as a continuous source of toxins. When this occurs, binders alone are not enough.

  We may use:

  • Nasal antifungal sprays (such as nystatin or amphotericin B)

  • Oral antifungal medications (such as itraconazole)

  This phase of treatment can take months and requires persistence.

4. Brain Training

Sometimes an area of the brain called the limbic system gets stuck in an “on” position. When this happens, the brain signals the rest of the body to remain ill. Fortunately, there are good programs to retrain this area of your brain to let go. We work with The Gupta Method, Primal Trust, and Dynamic Neural Retraining System to fix this area of your brain so you can get back to life. University studies of the Gupta Method suggest symptoms can improve by 50% or more by brain training techniques.

A Collaborative Process

Healing from mold toxicity is not a quick fix. It is a process that requires time, persistence, and partnership.

When you work with us, you are not just a patient: you are part of the process. We combine clinical expertise with your experience to build a plan that fits your needs.

Over time, we “peel back the layers,” addressing one obstacle after another until your system can function normally again.

Your Path Forward

For many people, mold toxicity is the missing piece to recovery from chronic fatigue syndrome, fibromyalgia, or chronic Lyme disease. For others, it’s a diagnosis of its own.

If you have chronic fatigue, fibromyalgia, or Lyme disease that is not improving, it’s essential to consider mold as a potential root cause.

With the right strategy (stabilizing your system, removing toxins, treating colonization, and restoring balance), recovery is possible.

It may take months to see significant change, but with a structured roadmap and the right support, you can reclaim your health and your life.
