I had Gastritis right during my episode of Crohn's prior to my diagnosis. The Endoscopy revealed pictures of my stomach lining that looked like a stewed Tomato.
I also was given a couple of different acid blockers, one which made it worse, and the other that did nothing.
I had three separate tests for H-Pylori, all were negative. I could not live with this much longer as it was giving me more trouble than my Crohn's.
Thanks to my skeptical nature about lab tests, I treated for H-Pylori anyway using an alternative treatment I have quite a bit of experience with. It killed the H-Pylori that I did have in my stomach and that was the last problem I ever had with it. The treatment I used only targeted the H-Pylori bacteria, and is not known to affect any other, so I am 99% certain that is what was killed.
In retrospect, this is what I believe happened. When I started getting my Crohn's symptoms, I was using a lot of antacids. Like two or three rolls of TUMS in a week.
I believe this weakened the stomach acid and allowed H-Pylori to move up into the normally hostile environment of my stomach. The acid blockers used later only made it even easier for the bacteria to multiply.
I am also fairly certain that the H-Pylori bacteria plays an important role in Crohn's Disease symptoms in general. It is one of the three that I think are involved.
