Upper gastrointestinal bleeding (UGIB) is gastrointestinal bleeding in the upper gastrointestinal tract, commonly defined as bleeding arising from the esophagus, stomach, or duodenum. Blood may be observed in vomit or in altered form as black stool. Depending on the amount of the blood loss, symptoms may include shock.
An upper GI bleed is more common than lower GI bleed. [2] An upper GI bleed occurs in 50 to 150 per 100,000 adults per year. [8] A lower GI bleed is estimated to occur in 20 to 30 per 100,000 per year. [2] It results in about 300,000 hospital admissions a year in the United States. [1] Risk of death from a GI bleed is between 5% and 30%.

It may be caused by ulcers, tumors of the stomach or esophagus, varices, prolonged and vigorous retching, gastroenteritis, ingested blood (from bleeding in the mouth, nose, or throat), or certain drugs.

When present, symptoms usually relate to painless bleeding, with vomiting blood (hematemesis) and/or black stools . [3] Less often, Dieulafoy's lesions may cause rectal bleeding (hematochezia), or rarely, iron deficiency anemia. Usually, there are no gastrointestinal symptoms that precede the bleeding (abdominal pain, nausea, etc.).
The Glasgow-Blatchford bleeding score (GBS) is a screening tool to assess the likelihood that a person with an acute upper gastrointestinal bleeding (UGIB) will need to have medical intervention such as a blood transfusion or endoscopic intervention. [1] The tool may be able to identify people who do not need to be admitted to hospital after a ...
