Gastritis Support Group
Gastritis is a medical term for inflammation of the lining of the stomach. It means that white blood cells move into the wall of the stomach as a response to some type of injury. Gastritis has many underlying causes, from infection with the bacterium H. pylori, bile reflux, or excessive consumption of alcohol or certain foods or drugs like aspirin.

Jim, I had an endoscopy Oct 2010 after treatment for H Pylori and they found erosion and mild gastritis. They also did biopsies and the it came back clean for HP and no sigh of cancer.
What were you taking and your dosage before this flare up?
A month or so after my endo, the symptoms mostly subsided, I still watched what I ate and had some acid once in awhile. If I had a mild flare, I just took omeprazole once a day for a few days and it got better. So, other than that I didn't take anything.
This last bout started I think with some mild food poisoning and it got a little better, then worse so here I am--again.
How are you, do you have yours under control?
When I had mine done (that's upper AND lower, btw, having the colonoscopy first), I had the option of being 'fully' awake or a heavier type of sedation. I had no interest in watching the screen, so I told them I want to be fully relaxed. They said no problem!
I don't even remember anything after they started the IV and told me to roll on my side! And the time went SO fast! I think most places are pretty accommodating to their patients if you tell them what you prefer.
Best of luck!
