Acute gastrointestinal (GI) hemorrhage frequently occurs because of bleeding duodenal ulcer. However, clients who are predisposed to having GI bleed or hemorrhage may be caused by their underlying conditions, like previous major surgery, renal failure, chronic liver damage secondary to alcohol abuse or hepatitis, myocardial infarction, and chronic pain conditions requiring NSAIDs as treatment.
It can be classified into two: upper GI bleeding and lower GI bleeding. It is classified according to what had precipitated the hemorrhage. Causes for upper GI bleeding may involve peptic ulcer disease, ruptured esophageal varices and gastritis. While a carcinoma or neoplasm, Crohn’s disease, ulcerative colitis, polyps, haemorrhoids and diverticulitis are some of the reasons for lower GI bleeding. It is considered to be an upper GI bleed if it affects the esophagus, stomach and duodenum but it is known to be otherwise if the bleeding occurs below the Treitz ligament.
