Approximately 1 in 20 people in the United States have hemorrhoids. They become much more common with age. Hemorrhoids occur inside the rectum the final part of the colon and around the outer area of the anus.

The blood from hemorrhoids is usually bright red. In certain cases, anal pain is due to a blood clot developing inside the hemorrhoid. This is known as a thrombosed hemorrhoid. Anal fissures , sometimes called anal ulcers, are small tears in the lining of the anus. These are autoimmune diseases , which cause your body to mistakenly attack itself. Your body sends white blood cells to parts of the digestive tract, where they release chemicals that cause damage, or inflammation , to the bowels.

These tests may include a rectal exam or fecal occult blood test to look for abnormalities or blood in your colon. The rectal exam is a physical exam which requires the doctor to touch you. The fecal occult blood test requires you to provide a stool sample. A doctor will first ask how much blood was visible in the bowel movement, and they may also order a test called a complete blood count to help determine the extent of the blood loss. The next steps depend on how much blood was lost.

If a person reports a large amount of blood loss and has a low blood count, the doctor may perform an urgent endoscopy. This involves inserting a thin, flexible tube with a camera at one end into the GI tract to look for the source of the bleeding. An upper endoscopy involves guiding the endoscope through the mouth and down into the upper GI tract.

A colonoscopy is a form of endoscopy that involves inserting the endoscope into the anus and through the lower GI tract.

Once the doctor has identified the source of the bleeding, they can insert tiny instruments through the endoscope and use them to repair the damaged tissue. If the doctor is unable to identify and resolve the bleed, they may recommend surgical removal of all or part of the damaged area.
