Welcome to the blog of Dr. Marcus Ettinger "Medical Detective" and "Digestion Coach"

I have been writing about health and the human body for over 35+ years. I do this to provide easy-to-understand information on complex topics. I also do this to cement everything I’ve learned in my brain. I hope the information presented on my blog helps you increase your understanding of the body, disease, and health.

What would YOU DO if all of your pain and anxiety causing symptoms disappeared?

If you are experiencing a health challenge that no one has been able to address, please give me a call. I handle challenging cases, especially involving the stomach and GI tract. These include H. pylori, biofilm protocols, leaky gut, SIBO, Crohn’s, ulcerative colitis, and many other conditions. Click on the icon above or call me at 714-639-4360.
