Feces or Rectal Bleeding

Buttock Rectum | Gastroenterology | Feces or Rectal Bleeding (Symptom)


Rectal bleeding refers to the removal of the blood (often mixed with remnants of the stool and / or blood clots) from the digestive tract through the rectum. It is called rectal bleeding because blood may come from the rectum but also from other parts of the gastrointestinal tract. The volume of the blood lost varies from case to case. It may be minimal - a situation in which patients lose a few drops of blood, faded - to severe bleeding which is quantitatively important.

Generally, mild rectal bleeding is evaluated and treated at the gastroenterologist office without the need for hospitalization or emergency diagnosis and treatment. Other times, rectal bleeding may be mild or severe. Patients with moderate bleeding will repeatedly show major leakage of blood, red or brown colour, often mixed with feces and / or blood clots. For people who have severe bleeding which may be increased during defecation is due to hard work. Regardless of type, moderate or marked, rectal bleeding may affect the overall health of any person, involving symptoms such as the decreased blood pressure, orthostatic hypotension (low blood when the patient suddenly stand up after lying or sitting ), dizziness, weakness or fainting.

Rarely, the volume of the removed blood is so important that the patient may determine entry into shock. However patients who lose a significant amount of blood could require emergency hospitalization and blood transfusion.


Many diseases and conditions can cause rectal bleeding. These most commonly are found: anal fissures; hemorrhoids; rectal cancer or polyps or colon; diverticulosis; abnormal blood vessels; ulcerative colitis; ulcerative proctitis; crohns colitis; infectious colitis; ischemic colitis; meckel diverticula.

Diagnosis and Treatment

Most cases can be diagnosed with rectal endoscopy, bowel endoscopy or barium exam. It may be need to make a stool culture and a stool examination. If the diagnosis is uncertain, we recommend a visit to a gastroenterologist for a colonoscopy and other tests. Endoscopy made by a gastroenterologist may require angiography for small intestines, and it is studied with radioisotopes.
