Description
Rectal bleeding refers to the passage of red blood from the anus, and the severity varies considerably. Most rectal bleeding originates in the colon, rectum, or anus. The color of the blood usually depends upon the location of the bleeding.
Most episodes stop on their own, and mild rectal bleeding can often be treated in the doctor's office without hospitalization.
Moderate rectal bleeding will repeatedly pass quantities of bright or dark red blood, often mixed with stools or blood clots. Severe bleeding will contain a large amount of blood. Moderate or severe bleeding can lead to symptoms of weakness, dizziness, fainting, or low blood pressure results from the depletion of blood in the patient's body.
A black, "tarry" (sticky) and foul smelling stool usually indicates bleeding in the stomach, where the blood is in the intestines for a longer period of time before it exits the body.
