My doctor says I need to get a colonoscopy. What should I expect?

A colonoscopy is an examination of the large intestine and rectum using a thin, flexible tube called a colonoscope. During the procedure, the colonoscope is inserted through the rectum into the colon. The scope is then moved along the length of the colon, allowing the doctor to take pictures and remove any polyps that may be found. You will likely experience some discomfort during the procedure, but it should not last long. After the procedure, you can expect to have soreness for a few days and possibly mild cramping or bloating.
