My doctor wants me to get a colonoscopy. What is that, and what should I expect?

A colonoscopy is a procedure in which a doctor uses a thin, flexible tube with a camera at the end to look inside your colon. The doctor will insert the tube into your rectum and slowly move it through your colon, allowing the camera to take pictures of any polyps or other abnormalities. You may experience some discomfort during the procedure, but most people tolerate it well.
