I'm really confused :( Iv gotten differing diagnoses & prescriptions since I was 15 for my stomach problems. ie; Heartburn, IBS, gastric reflux? I have constipation, pretty sure it's from the meds I take. My bowels dont move unless I take a laxative. I put myself on a bland diet avoiding spicy foods citrus fruits sugar caffeine alcohol not eating anything heavy after 7pm. I take Omeprazole, it works. Had an endoscopy recently, found a small errosion on esophagus (Barretts Syndrome) And once in a blue moon after a meal I start to burp a terrible smell like rotten eggs. Followed by nausea & vomiting then diarrhea.
