Mold Illness
Over the years, this condition has had many names. Let’s begin with a key point: mold illness is not an allergy.
It is an inflammatory illness, triggered when the immune system becomes dysregulated after exposure to mold and its toxins. For those also struggling with Lyme disease, mold and mycotoxins can overwhelm the immune system, making it far more difficult to recover from tick-borne infections.
What Is Mold Illness?
Mold illness results from exposure to mold spores and mold biotoxins. Biotoxins are toxic substances produced by biological organisms such as molds and bacteria.
The condition is a type of biotoxin illness known as Chronic Inflammatory Response Syndrome (CIRS), first defined by Dr. Ritchie Shoemaker in the late 1990s. Since then, our understanding of mold-related illness has grown significantly.
Though not yet universally accepted by all clinicians, there are a growing number of practitioners making a real difference in patients’ lives. This gives hope to anyone struggling with mold illness.
For further resources, see the International Society for Environmentally Acquired Illness (ISEAI), whose mission is to:
“Raise awareness of the environmental causes of inflammatory illnesses and to support the optimal health of individuals affected by these illnesses through the integration of clinical practice, education, and research.”

I am a member of ISEAI and participate in ongoing mentorship with mold experts Dr. Neil Nathan and Dr. Jill Crista. While there is still more to learn, we now know: living with mold toxicity and CIRS is not without solutions — people can and do recover.
Testing for Mold Toxicity
I use:
Real Time Laboratories urine testing
This test is often done following a glutathione challenge to better capture biotoxin load.
Symptoms of Mold Toxicity
Mold-related symptoms are commonly misdiagnosed and frequently overlap with tick-borne illness symptoms. A thorough exposure history combined with objective lab data is essential for accurate diagnosis.
For self-screening, patients can use the Crista Mold Questionnaire to assess the likelihood of mold-related illness.
