I've heard that a colonoscopy is not a pleasant experience. What should I expect?

A colonoscopy is a procedure in which a doctor uses a thin, flexible tube called an endoscope to examine the inside of your large intestine. The doctor will insert the endoscope into your rectum and then slowly move it through your colon. During the examination, the doctor may take biopsies or remove polyps (growths) from your colon. This can be a painful process, but you will be given medication to help with any discomfort.
