A member asked:
Why do i have black poop after colonoscopy?
A doctor has provided 1 answer
Could be bleeding...: Black poop after colonoscopy may reflect blood in your stool, especially after having polyps removed during the procedure. Other causes could relate to your preparation used to clean out your colon, or entirely unrelated issues such as bismuth medication or even blood from your upper GI tract. This symptom should be reported to your surgeon promptly.
