Welcome to the blog of “The Digestion Coach,” Dr. Marcus Ettinger.

As a practicing doctor of 36+ years and GI health specialist, I have studied, written, and treated the human body for a long time. I created this blog to provide easy-to-understand information on complex topics and to help anchor everything I study. I hope the information on my blog increases your understanding of the body, disease, and health.
