A colonoscopy is a procedure used to inspect the colon (large bowel). A thin flexible tube with a camera called a colonoscope is used to examine the colon. It is usually done in an endoscopy centre or a hospital as a day procedure. A colonoscopy is used to detect inflammation, ulceration or abnormal growths such as polyps or colorectal cancer. It can be helpful to diagnose changes in bowel habits, abdominal pain, rectal bleeding or for screening for polyps or colorectal cancer.
In order to get the best possible view of the colon and to make the colonoscopy easier and safer, it is important that your colon is cleaned out.
