Doctors always go the wrong way and advise completely the wrong thing for GERD and Reflux. Drug PPIs are a huge danger to both your intestines and your immune system.
GERD and Reflux aren't caused by high stomach acid -- it's caused by stomach acid that's way too low. Don't believe me? Then do a google search on "GERD low stomach acid" and see what that tells you.
Here's my cure for GERD, Reflux and Low Stmoch acid. See this link.
If you still don't believe that GERD is caused by low stomach then just ask your doc for a Heidelberg Test(google it). That will tell you whether you have too little or excessive stomach acid.
