My doctor says I need to have a colonoscopy. What is it like?

A colonoscopy is a procedure in which a doctor uses an endoscope, a long, flexible tube with a camera on the end, to look inside your colon. The doctor will use the endoscope to examine the entire length of your colon, looking for any signs of disease or polyps. The doctor may also remove any polyps they find during the exam. After the exam, the doctor will clean out your colon and you will be given instructions about how to care for yourself after the procedure.
