[|Human|] I had a colonoscopy 2 days ago. The doctor removed a 7.5cm polyp (yes very large). Following the procedure I had 4 bowel movements (within 2 hours of returning home from the procedure) which were all blood. I have not had a bowel movement since. I feel that I have to go and am experiencing moderate abdominal pain. Is this normal?
[|AI|]  Hi. Thanks for your query and an elucidated history. When such a large polyp has been removed, you had 4 bowel movements containing blood only, this means there was a bleeding and may be still continuing or may be there is a hematoma in the wall of the colon. All these factors together can cause pain in abdomen after colonoscopy. You Need to get admitted for under-observation and if required a second-look colonoscopy with control of any condition which is causing the pains.
