  • Summary

    Upper gastrointestinal bleeding (UGIB) is bleeding proximal to the ligament of Treitz (esophageal, gastric or duodenal source). More common than lower gastrointestinal bleeding (LGIB; approximately 70% of GIB). Most common cause is peptic ulcer disease. LGIB is bleeding distal to the ligament of Treitz. Lower gastrointestinal bleeding is less common than UGIB (approximately 30% of GIB). LGIB has lower mortality rate than UGIB. The most common cause is diverticular disease.
