Gastritis, I think, means different things to different people. I had various symptoms, or ‘stomach’ issues. I read a book called The Keystone Aporoach and it led time to do two things, take coated peppermint pills (empty stomach only) and probiotics (I chose Pro-50) and my issues are 90% better. I am not recommending you do any of this but rather read the book if that sounds if interest and see if there is something that rings a bell.
Most importantly you may want to see a doctor if it persists. I hope this helps:)

I have terrible stomach problems! I have IBS and Diverticulitis. Lots of gas and diarrhea. No fun!!

And am in hospital admission

Ok thanks my dear.Its severe chronic gastrisis. Am currently using probiotics

Hi Tate, Please be careful with taking probiotics as with some people they can cause or make gastritis much worse. Depends on your symptoms, and I would urge you to be cautious just taking probiotics off the shelf. Maybe a better way to deal with it.
