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.
