How risky is a colonoscopy?

A colonoscopy is generally a safe procedure, but like any medical procedure, it does carry some risks. The most common risks associated with a colonoscopy include:

* Bleeding. During the procedure, the colonoscope may cause small tears or abrasions in the colon, which can lead to bleeding. In most cases, this bleeding is minor and stops on its own. However, in some cases, more significant bleeding may occur, which may require treatment.

* Infection. The colonoscope can introduce bacteria into the colon, which can lead to infection. This is a rare complication, but it can be serious if it occurs. Symptoms of a colonoscopy-related infection may include fever, abdominal pain, and diarrhea.

* Perforation. The colonoscope can also cause a perforation, or hole, in the colon. This is a rare complication, but it can be life-threatening if it occurs. Symptoms of a perforation may include severe abdominal pain, fever, and vomiting.

* Colonoscopy-induced colitis. This is a rare condition that can occur after a colonoscopy. It is characterized by inflammation of the colon and can cause symptoms such as abdominal pain, diarrhea, and weight loss.

The overall risk of serious complications from a colonoscopy is low. However, it is important to be aware of the potential risks before undergoing the procedure.
