Mold illness is one of the most underdiagnosed and misunderstood chronic conditions in medicine. Functional medicine practitioners in Houston specialize in identifying mycotoxin exposure, testing for CIRS, and guiding patients through a structured path to recovery.

Houston is one of the highest-risk cities in the United States for mold exposure. The combination of high humidity, Gulf Coast weather patterns, frequent flooding events - including major hurricanes and tropical storms - and an enormous aging housing stock creates ideal conditions for mold growth inside homes, offices, and schools. Many Houston residents are living or working in mold-contaminated environments without knowing it.
What makes CIRS particularly difficult is that approximately 25% of the population carries a genetic variant (specific HLA-DR immune genes) that prevents their immune system from properly clearing biotoxins. For these individuals, mold exposure triggers a sustained inflammatory response that conventional medicine rarely identifies correctly - leading to years of misdiagnosis and ineffective treatment.
Mold illness affects virtually every system in the body. The Shoemaker symptom cluster - the diagnostic framework used by leading CIRS practitioners - includes:
If you have experienced a significant water damage event in your home or workplace - even years ago - and have struggled with unexplained multi-system symptoms since, mold illness should be seriously investigated.
The Shoemaker Protocol is the most evidence-based framework for diagnosing and treating CIRS. Functional medicine practitioners trained in this protocol use a specific sequence of lab testing, visual contrast sensitivity testing, and symptom cluster analysis to confirm diagnosis and guide treatment.
Urine mycotoxin testing identifies the specific toxins being produced by mold species in your environment and stored in your body. Different mycotoxins require different treatment approaches - making identification essential before treatment begins.
Treating mold illness while remaining in a moldy environment is not possible. Your practitioner guides you through the environmental assessment process - including ERMI testing, HERTSMI-2 scoring, and how to evaluate your living and working spaces.
CIRS drives a specific pattern of immune dysregulation that includes elevated inflammatory markers, complement activation, and dysregulated cytokine production. Functional medicine practitioners monitor and address this pattern systematically throughout treatment.
Mold toxins are particularly damaging to the nervous system and brain. Cognitive symptoms - brain fog, memory loss, word retrieval problems - are among the most debilitating features of CIRS. Treatment includes targeted neurological support and monitoring cognitive recovery over time.
Mold illness and Lyme disease frequently coexist and share many symptoms. A significant percentage of patients with one condition have the other. Experienced functional medicine practitioners assess and treat both simultaneously when present.

"After Hurricane Harvey my health fell apart completely. I saw 7 doctors in 2 years with no answers. My functional medicine practitioner in Houston identified CIRS within the first visit and I finally had a name for what was happening."
- Patricia G., Houston TX
"The cognitive symptoms were the worst part - I felt like I was losing my mind. My practitioner treated the mold illness and the neurological symptoms gradually lifted. I'm back to being myself for the first time in years."
