Gastrointestinal bleeding: Introduction
Gastrointestinal bleeding is an abnormal condition in which there is blood or bleeding that appears with vomiting, from the throat, from the rectum, or blood that accompanies or is mixed in with feces.
Gastrointestinal bleeding is a symptom of a wide variety of conditions. They include peptic ulcer, intestinal polyps, diverticula, inflammatory bowel disease, gastrointestinal prolapse, colorectal cancer, gastrointestinal abscesses, intestinal infections, constipation, or anal fissures. Gastrointestinal bleeding can also be a side effect of certain medications, such as aspirin, heparin, Coumadin, and ibuprofen.
Gastrointestinal bleeding can indicate a mild condition, such as hemorrhoids, or it can accompany a serious, even life-threatening condition, such as esophageal varices.
Gastrointestinal bleeding can appear in a variety of forms. Bright red bleeding may occur during vomiting or blood may be mixed with material that is vomited up (vomitus). Blood in small amounts may also be hidden in vomitus and not be visible to the naked eyes. Blood in vomitus may also have a dark, black or coffee-ground appearance. This is often diagnosed as upper gastrointestinal bleeding. Blood clots can also be present with upper gastrointestinal bleeding.
Gastrointestinal bleeding can also appear in 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.
Another type of gastrointestinal 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 (fecal occult blood). Bleeding from the rectum or blood in the stool may be diagnosed as lower gastrointestinal bleeding or upper gastrointestinal bleeding, depending on the location in the gastrointestinal tract where bleeding occurs.
There are many complications and symptoms that can accompany gastrointestinal bleeding, depending on the underlying cause of the bleeding. Symptoms often involve the gastrointestinal system but can affect other body systems as well. For more details about symptoms and complications, see symptoms of gastrointestinal bleeding.
Diagnosing gastrointestinal bleeding and its underlying 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 in the office using an anoscope, which is inserted a short way into the rectum to look for causes of gastrointestinal bleeding, such as internal hemorrhoids.
Blood tests include a complete blood count (CBC), which can determine if there is significant enough bleeding to cause anemia. Blood clotting tests may also be done to evaluate how well the blood clots.
Making a diagnosis of gastrointestinal 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 gastrointestinal bleeding and its cause can easily be delayed or missed because tiny amounts of blood may not be visible to the naked eye. For information on misdiagnosis, refer to misdiagnosis of gastrointestinal bleeding.
Treatment of gastrointestinal bleeding varies greatly depending on the underlying 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 gastrointestinal bleeding. ...more »
