My doctor wants me to get a colonoscopy. How does that work?

A colonoscopy is an examination of the large intestine using a thin, flexible tube with a camera at the end. It allows doctors to see the inside of your colon and rectum and can help diagnose certain diseases or conditions. The procedure involves inserting the tube through the rectum into the colon. You may be given sedatives for comfort during the procedure. After the procedure, you will need to rest for a few hours before returning home.
