blood in stool

The presence of visible or clinically detectable hemoglobin in feces. Bright red blood in stool is known as hematochezia. It may be produced by anorectal disorders, such as hemorrhoids, or by bleeding from diverticuli, cancers, some forms of dysentery, or angiodysplasia of the bowel (among other causes). It sometimes results from massive bleeding from the upper gastrointestinal tract.
