Hard 2 say: But there are many other non-blood causes of dark stools (meds, diet, etc) . Fortunately it is easy to tell by bringing a small sample to your md to test for blood. If blood is found a colonoscopy and upper endoscopy could be performed to rule out a source of bleeding. If no blood, may be dietary. See a doctor.
