Oily stools: Oily stools can be seen in irritable bowel syndrome but also with malabsirption of fats caused by high fat ingestion, gall bladder,liver pancreatic disorders or gluten intolerance or sensitivity. Your gastroenterologist will be able to advise you and order appropriate testing. Foul smelling stools, in my opinion, is nonspecific.
