Hi I can understand your concern.... See let me know you after post cholecystectomy bile acid enter in intestine constantly in low amount....As reservoir for bile that is gall bladder not present.... So fatty food digestion not proper.... This is called bile acid diarrhea.... Sometime diarrhea can be by leakage of bile to adjacent structures like stomach , intestine.... Now for treatment of diarrhea in some pateint dietary modification is helpful.... Like take low fat foods.... Fruits more.... Heavy meal restricted.... If still no benefit then we can use bile acid sequestrant like cholestyramin and colestipol... Antispasmodic drug also can be used.... Besides this no other drug tried.... Consult gastroentetologist with keeping this in mind.... Take care. Dr.Parth
