Perhaps nothing: But there are many causes of dark stools (blood, 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, it may just be diet or other normal cause.
