Colonoscopy enables your Gastroenterologist to examine the lining of your colon (large intestine) for abnormalities by inserting a flexible tube into your rectum and slowly advancing it into the colon. You will be sedated to help you relax and better tolerate any discomfort. You will be lying on your left side while your doctor carefully advances the colonoscope through the large intestine. This test is usually preferred at 45 years of age. This is the “Gold” standard for cancer prevention. If polyps are seen they can be removed during the procedure. You might also have this test if you have a change in bowel pattern, blood in your stool, or lower abdominal pain. An inflamed area can be biopsied and a narrowed area can be dilated. The procedure takes about 15-20 minutes with 30-60 minutes additional recovery time. You will need a driver because of the sedation.
