White Coat Black Sheep

David has spent nine years building a following of more than half a million subscribers for his police accountability work in the San Joaquin Valley. Off camera, he's spent almost as long trying to figure out what's actually wrong with his gut. GERD as a kid. An acid reflux diagnosis in his twenties. A diverticulitis flare up that led to antibiotics one doctor now says he never needed. A proton pump inhibitor that sent him into a middle of the night crisis. And a phone call with his primary care doctor that ended with an offer of antidepressants and the suggestion that he stop Googling his symptoms.

In this episode, 
Dr. Civelli sits down with David to walk through his entire health history, symptom by symptom, and talk about what a real root cause workup actually looks like: stress, activity, food, and the testing most doctors never mention because insurance rarely covers it.
