Most people assume that once they leave a mold-exposed building, their body should recover. But I see this all the time in my clinic, the mold exposure ends, and the symptoms don't.

In this episode of Extend, I sit down with Dr. Scott McMahon, medical director at MoldCo, to ask why removing the source doesn't always mean removing the illness. We get into a switch inside the immune system, one that determines whether the body can actually call off an inflammatory response once a threat is gone, and what happens when that switch stops working. Understanding it changes how a long list of unexplained, lingering symptoms starts to make sense.

Dr. Scott McMahon spent eighteen years as a pediatrician before a case involving a group of sick high school students redirected the entire focus of his career. He went on to study under Dr. Richie Shoemaker, the physician who first identified Chronic Inflammatory Response Syndrome (CIRS), and has spent years treating patients, publishing research on the condition's diagnostic criteria, and co-authoring a book on CIRS medicine. As medical director of MoldCo, he now works at the intersection of testing, treatment, and education for a condition that affects an estimated one in four people genetically, making him one of the most credible voices in the country on this topic.

What's Discussed:

(3:43) The high school case that revealed how multi-system illness can hide behind symptoms doctors are trained to treat separately.

(6:55) The difference between a mold allergy and a full immune system malfunction, and why they are not the same thing.

(10:29) What determines whether one person's body can shut off inflammation and another person can't.

(12:34) The ten lab markers that can actually confirm what's happening, and why most physicians have never ordered them.

(17:41) Why a popular at-home mold test might be telling you less than you think.

(21:41) How to check your own home for the signs most people walk right past.

(35:17) The real number of people walking around with this genetic predisposition, and why it's higher than almost anyone expects.

If symptoms have stuck around well after leaving a mold-exposed space, this conversation breaks down why, and what's actually keeping the body in that state long after the exposure ended.
