Hi and welcome to Healthcaremagic. Thank you for your query. I am Dr. Rommstein, I understand your concerns and I will try to help you as much as I can. First ,these symptoms may indicate some serious disorders such as inflammatory bowel diseases or even tumors so it should be evaluated first with colonoscopy. if there is no organic cause then you can use certain medications such as bismuth subsalicylate (Pepto-Bismol) or loperamide (Imodium).In cases of infectious diarrheas, you should do microbiologist testing of stool and see the exact microbe and then antibiotics can be used additionally. I hope I have answered you query. If you have any further questions you can contact us in every time.
