What are the common complications that arise from colonoscopy or endoscopy?
The common complication from these procedures is related to conscious sedation. Many patients feel sleepy and tired after the procedures. After colonoscopy, bloating and cramps is common. The more serious complications include bleeding or perforation. Bleeding may occur after a polyp is removed. With significant bleeding, you will see fresh, red blood in your stool. A perforation of your bowel will cause severe abdominal pain and fever. For these serious complications, it is important for you to be evaluated quickly in the MGH emergency department or a one closer to you.
