A2 - Loscalzo, Joseph PY - 2018 T2 - Harrison's Principles of Internal Medicine, 20e AB - Gastrointestinal bleeding (GIB) is the most common gastrointestinal condition leading to hospitalization in the United States, accounting for over 507,000 admissions and $4.85 billion in direct costs annually. Upper GIB (UGIB) incidence has decreased in recent decades, primarily due to decreases in GIB from ulcers. The ratio of UGIB to lower GIB (LGIB) among GIB admissions from U.S. emergency rooms is ~1.3. The case fatality of patients hospitalized with GIB has also decreased and is <3% in the United States. Patients generally die from decompensation of other underlying illnesses rather than exsanguination.
