I have growling and loud popping noise gas/air. had took medicine for gerd but noise is still its been bout 3 wks what could it be. hope nothing bad?

Gas: We hope so too. I would ask the gastroenterologist if your digestion is working satisfactorily. Were you taking any antibiotics before this? Most cases are not anyting serious.

Consider: changing diet. if lactose or milk products make it worse avoid them or use lactaid , if foods with gluten try gluten free diet and avoid gaseous food and try OTC simethicon
