A thorough evaluation by your doctor is important any time bleeding from the rectum or blood in the stool lasts more than a couple of days. Your doctor may advise the following:
- Digital examination: Your doctor will examine the anus and rectum to look for swollen blood vessels that indicate hemorrhoids and will also perform a digital rectal exam with a gloved, lubricated finger to feel for abnormalities.
- Proctoscopy: Proctoscope is an instrument used to visualize the internal hemorrhoids and the whole rectum.
- Sigmoidoscopy: It is done to rule out other causes of bleeding (like cancer of rectum, anal fissure, Crohn’s disease).
- Colonoscopy: It is done to examine the entire colon (large intestine) and rule out other problems (pathologies) in colon which could be responsible for bleeding through the anal canal.
- Barium meal X-ray: It is done to see the entire inner part of colon to visualize any abnormality there.
