Thanks, I wasn't worried about the gastritis or the hemorrhoids, it was the "thickening" that concerned me. Googling it resulted in colon cancer hits. I believe he said he took biopsies to check for microscopic colitis. I'm sure it's probably nothing to worry about.
As far as the gastritis goes I'm a little confused how to treat it. He really pushes PPI''s like prilosec etc, but I have read they can do more harm than good. Low acid can actually be the cause of gastritis. I tried supplementing with HCL for this reason but just one pill burned like crazy so I was afraid to try it again.
