[/INST] Hi. Thanks for your query. Your symptoms complex of treated H-Pylori infection of the stomach yet the presence of rumbling in the abdomen, flatulence, passing of gases per anus, pain in upper abdomen and so on can be related to the single most cause of such symptoms called Irritable Bowel Syn Chat Doctor. But before we label you as suffering from IBS, you need to undergo some tests which should be normal.:viz.CT scan of the abdomen, Colonoscopy Enterocolitis. A course of an antibiotic, metronidazole. Once all these investigations are normal, you have to start treatment for IBS. Continue probiotic for a long time. </s>
