How Are Piles Diagnosed?

A thorough evaluation and proper diagnosis by the doctor is important any time bleeding from the rectum or blood in the stool lasts more than a couple of days. Bleeding may also be a symptom of other digestive diseases, including colorectal cancer. Closer evaluation of the rectum for piles requires an exam with proctoscopy.

To rule out other causes of gastrointestinal bleeding, the doctor may examine the rectum and lower colon (sigmoid) with sigmoidoscopy or the entire colon with colonoscopy.
