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

A colonoscopy is an examination of the large intestine, which involves inserting a thin, flexible tube into the rectum and slowly advancing it through the entire length of the colon. The procedure usually takes about 30 minutes to complete and requires no sedation or anesthesia. During the exam, your doctor will look for any signs of polyps, cancerous growths, inflammation, or other abnormalities in the lining of the colon. If any are found, they can be removed during the procedure. After the procedure, you may experience cramping, bloating, gas, and mild discomfort, but these symptoms should pass quickly.
