Gastrointestinal Bleed, Lower, Discharge Information

What is a lower gastrointestinal hemorrhage?

A lower gastrointestinal (GI) hemorrhage, also called lower GI bleeding or rectal bleeding, is abnormal blood loss from the colon, rectum, or anus (the opening of the rectum). It is usually seen as blood on or in a bowel movement, on the toilet tissue after wiping, or in the toilet bowl water. The blood may be easily seen or it may be hidden, requiring testing of the bowel movements to know it is there.

Common causes of rectal bleeding include tears in the skin of the anus or hemorrhoids. Bleeding may also be from small pockets (diverticula) that form in weak parts of the colon wall and stick out. These pockets or pouches can bleed and may not stop bleeding on their own. Other possible causes include infections of the intestine, inflammatory bowel disease, colon cancer, or bleeding in the upper digestive system.

How can I take care of myself when I go home?

How long it takes to get better depends on the cause of your lower GI bleed, your treatment, how well you recover, your overall health, and complications you may have. You may need to make lifestyle changes to improve your health and to help keep the lower intestine as healthy as possible, prevent GI irritation, or prevent another lower GI bleed. Some simple lifestyle changes can help the intestines work better, as well as prevent constipation, hemorrhoids, and diverticula.
