I am suffering from chronic stomach pain. Some times I feel nauseated. 8 years ago I was treated for gastritis and H pylori bacterial infection. Can it reoccur? I pass lot of wind during evening n night after eating food. Bowel movement is ok but it takes long time for complete evacuation. I am a thyroid patient taking 125 mg thyronorm daily. My hysterectomy was done last year owing to fibroids in uterus. Please suggest.
