My doctor wants to do a colonoscopy on me. What should I expect?

A colonoscopy is a procedure that involves the insertion of a long, thin tube into the rectum and colon for examination of the inside of the large intestine. The procedure can be uncomfortable but generally painless. You may be given medication to help with any discomfort. During the exam, the doctor will use an endoscope to view the inside of your colon. If needed, biopsies may be taken from the lining of your colon. After the exam, you will likely be asked to rest for several hours before being discharged.
