In this Made for Health minisode, Dr. Aaron Hartman continues exploring a question he hears frequently from patients: Why am I still sick? Why am I not getting better? What has been overlooked?
Sometimes you've seen multiple doctors, received diagnoses, tried medications, completed specialized testing, and even worked with functional medicine practitioners, yet your recovery eventually reaches a plateau.
According to Dr. Hartman, one potential piece worth investigating is mold exposure.
He explains that mold and other biotoxins can interact with the immune system in complicated ways. One aspect of this is Chronic Inflammatory Response Syndrome (CIRS), which Dr. Hartman describes in relation to activation of the innate immune system by biotoxins. He also discusses direct toxin exposure and how mold-related problems may intersect with autoimmune and inflammatory conditions.
The challenge is that mold exposure can be easy to dismiss precisely because it is so common. A water-damaged environment or mold around an HVAC system may look “normal” to someone who sees it every day, but Dr. Hartman argues that common does not necessarily mean harmless for every individual.
