I have chronic gastritis for some unknown reason. I know I have gallstones and wonder if that could cause the gastritis? FYI - If anyone here has gastritis I will share one med that made me feel alot better. It is a older medication called Cafercate. It really coats your stomach and protects it from stomach acids and bile, so it can heal. It acts like a bandage over inflamed areas in your stomach. They are large tablets you take with a little water. In addition, I am now taking Nexium twice a day. Hopefully I will be better soon. If anyone else has gastritis I would be interested to know how you treat it. Does it cause you to have a poor appetite?
