A colonoscopy allows your doctor to view the entire colon using a device called an endoscope. As the scope moves into your colon, your doctor views the output on a monitor to check for growths or polyps. Also known as the large intestine, the colon is responsible for the final stages of the digestion. It absorbs remaining water and electrolytes from indigestible food, accepts and stores food remains that weren’t digested in the small intestine, and eliminates solid waste from the body.
