Bleeding from the lower gastrointestinal tract represents a significant source of
morbidity and mortality. The colon represents the vast majority of the location of
bleeding with only a much smaller incidence occurring in the small intestine. The
major causes of lower gastrointestinal bleeding (LGIB) are from diverticulosis, vascular
malformations, and cancer. We discuss the incidence and causes of LGIB.
