Welcome to the gastroenterology community! I would not recommend researching "what can go wrong in a colonoscopy
." Yes, things do go wrong, but in over 99% of the cases, everything is fine. I (and most other people) will tell you that the worse part of a colonoscopy
is the prep because it tastes bad and because you have to spend all day having diarrhea. I had a colonoscopy
at 16 and I was totally fine. Do you know what type of sedation you are going to get?
