A colonoscopy is a procedure in which a thin tube with a camera is used to look inside the colon, which is the lowest portion of the gastrointestinal tract. The camera allows Dr. Noorbhai to see images of the colon on a screen and take samples to test for abnormalities.
You will be given instructions before this procedure to prepare. A colonoscopy is usually done while you are conscious with a sedative. You will be asked to lie on your side and bend your knees for the procedure. A thin flexible tube with a camera is inserted into the anus slowly. The tube is guided through the rectum and colon and carbon dioxide is used to inflate the colon so that Dr. Noorbhai may observe and accurately diagnose you. He may also take a sample of the colon to test for abnormalities. This procedure may be uncomfortable but only takes 40 minutes to complete.
A colonoscopy is recommended as it is able to screen for colon cancer and conditions such as unexplained changes in bowel habits, pain in the abdomen, unexplained constipation, diarrhoea or weight loss. Colonoscopies should be done once a year for those over the age of 50 to screen for colon cancer.
Most colonoscopies are done within 40 minutes while you are conscious with a sedative. You will be advised to have someone drive you home and look after you afterwards while the sedative wears off.
