Undiagnosed Infections Are Silently Causing Chronic Disease | Dr. Richard Horowitz

Author: Dr. Mark Hyman July 29, 2026 Duration: 1:19:57
Living with chronic illness can feel like collecting diagnoses without getting real answers. Symptoms are treated one at a time, but the underlying causes can easily be missed. What if asking a different question is the first step toward feeling better? In this episode, I’m joined by Dr. Richard Horowitz, an internationally recognized Lyme disease expert and author of the new book Ending Chronic Illness. After caring for thousands of patients over more than four decades, he explains why many seemingly unrelated conditions share common underlying drivers—and why thinking like a medical detective may help uncover them. We discuss: Why treating the diagnosis isn't always the same as treating the problem—and how to start looking deeper How hidden infections, environmental toxins, gut health, and other overlooked factors can quietly drive chronic illness What new research may reveal about the links between infection, inflammation, and brain health How to begin uncovering what's really driving persistent symptoms Our bodies are constantly communicating with us. The challenge isn't that they're silent—it's that we haven't always known how to listen. Sometimes finding better answers begins with asking different questions. Continue Exploring If you'd like to explore Dr. Horowitz's work further, here are two great places to start: Take his Symptom Assessment Quiz to better understand what may be contributing to your symptoms.
