Hi. Thanks for your query. Noted the history and understood your concerns. Since you are suffering from gastritis for such a long time with three endoscopy, medications but still have the problem means there is something beyond the regular investigations, causes to be found and thus I would advise you the following: CT scan of the whole abdomen , particularly for pancreas and upper abdomen to see for the tumors like gastrinoma, GIST and so on. Upper GI Endoscopy. Psychological evaluation and control of stress and anxiety. Continuation of medical management. Get treatment for any other medical problems if you have. Change of lifestyle to suit the calm and quiet life. Small frequent meals. Soft bland diet.
