Rectal bleeding

Rectal bleeding: Introduction

Rectal bleeding is an abnormal condition in which there is bleeding from the rectum or blood that accompanies or is mixed in with feces. Rectal bleeding can be the result of a wide variety of conditions, such as hemorrhoids, diverticula, inflammatory bowel disease, rectal prolapse, colorectal cancer, rectal abscesses, intestinal infections, peptic ulcer, intestinal polyps, constipation, or anal fissures.

Rectal bleeding can indicate a mild condition, such as hemorrhoids, or it can accompany a serious, even life-threatening condition, such as esophageal varices.

Rectal bleeding can appear in a variety of forms. There may be small amounts of bright red blood that is mixed with stool or that shows up on toilet paper after wiping. Bright red blood can also be discharged from the rectum in small to massive amounts without an accompanying bowel movement. Blood clots can also be present with rectal bleeding.

Another type of rectal bleeding occurs when there is blacken blood mixed in with stool. Stools may appear black and tarry, or maroon in color. Blood in the stool may also be in such small quantities that it cannot be seen by the naked eye. This is called fecal occult blood, and may indicate a serious condition.

There are many symptoms that can accompany rectal bleeding, depending on the cause of the bleeding. Symptoms often involve the gastrointestinal system but can affect body systems as well. For more details about symptoms, see symptoms of rectal bleeding.

Diagnosing rectal bleeding and its cause begins with taking a thorough personal and family medical history, including symptoms, and completing a physical examination. A digital rectal examination and testing for fecal occult blood are generally performed at this time. A digital rectal examination involves inserting a finger into the rectum to feel for any abnormalities and obtain a sample of stool.

The stool sample is then tested for fecal occult blood, which can indicate invisible, hidden blood in the stool. Your health care provider may also examine the rectum using an anoscope, which is inserted a short way into the rectum to look for causes of rectal bleeding.

Making a diagnosis of rectal bleeding may also include performing special imaging tests to see a picture of the insides of the gastrointestinal tract. These may consist of some combination of tests, such as a barium X-ray, CT scan, MRI, and a variety of tests using video imaging technology. These include sigmoidoscopy or colonoscopy. These tests involve passing a small flexible tube fitted with a camera through the anus into the colon to look for abnormal areas and sites of bleeding. During this procedure, samples of tissue may be taken to be tested to confirm a diagnosis. The upper areas of the gastrointestinal tract can be examined in a similar way through the mouth and esophagus in an endoscopy procedure.

A diagnosis of rectal bleeding and its cause can easily be delayed or missed because tiny amounts of blood may not be noticeable. For information on misdiagnosis, refer to misdiagnosis of rectal bleeding.

Treatment of rectal bleeding varies greatly depending on the cause and a variety of other factors. Some conditions can be easily and successfully treated, while other may require intensive treatment. For more information on treatment, refer to treatment of rectal bleeding....more »
