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.
I would strongly advise you to see a gastro specialist and get a proper opinion. This is not a time to self-diagnose and find cures on the internet. Do that when you know what's going on, THEN research ways to address it. Right now you run a very high chance of just making yourself worse.
