How : How long have you had this problem? Is your stool loose or normal? If it is sudden then you may be dealing with an infectious cause, viral more likely than bacterial. If viral then your symptoms will likely resolve in a week or two. You could also be dealing with lactose intolerance, irritable bowel syndrome, or even a more serious inflammatory bowel disease like crohn's. Regardless, you need to be evaluated by your doctor for work up and treatment plan. Good luck.
