This document discusses lower gastrointestinal bleeding, which occurs distal to the ligament of Treitz. It notes that lower GI bleeding is one of the most common symptoms encountered in outpatient departments, accounting for about 20% of cases of gastrointestinal bleeding, with the colon most often involved and the small intestine accounting for only 5% of cases. It also mentions that lower GI bleeding has a male predominance and increases in incidence with the age of the patient.
