Ep. 9: Is Histamine Causing Your Acid Reflux? | GERD, MCAS & Low Stomach Acid Explained

Think reflux is just about “too much acid”?

In this episode of Reflux Revolution, we sit down with Dr. Zachary Spiritos, a Duke-trained gastroenterologist and expert in neurogastroenterology, to explore what’s really behind chronic reflux, GERD, and LPR.
