A flexible sigmoidoscopy allows the physician to examine the bottom third of the colon, which includes the rectum, the sigmoid and the descending colon, by using a flexible endoscope. Flexible sigmoidoscopy can detect inflamed tissue, abnormal growths and ulcers. The procedure is used to look for early signs of cancer and can help doctors diagnose unexplained changes in bowel habits, abdominal pain, bleeding from the anus and weight loss.
How Should I Prepare for Flexible Sigmoidoscopy?
A laxative or an enema may be required before a flexible sigmoidoscopy. You should inform your doctor of all medical conditions, and any medications, vitamins or supplements you take regularly, including aspirin products, arthritis medications, blood thinners, diabetes medications and vitamins that contain iron.
