My doctor wants me to have a colonoscopy, but I'm afraid of the risks. What are the risks?

The most common risk associated with a colonoscopy is a small risk of bleeding or infection. Other potential risks include abdominal pain, nausea and vomiting, bloating, cramping, fatigue, headache, fever, and difficulty passing gas. In rare cases, a colonoscopy can cause damage to the large intestine, which could lead to serious health problems.
