[Gastrointestinal bleeding in old age].

Gastrointestinal bleeding is a frequent symptom, with increasing age as a risk factor. Upper, middle and lower gastrointestinal bleeding are differentiated depending on the location, whereby only upper and lower gastrointestinal bleeding are elucidated in this article. The symptomatology varies depending on the localization of the bleeding. German and international clinical guidelines currently exist for the preclinical and clinical management of gastrointestinal bleeding. The main focus of the article is on pre-endoscopic management of upper gastrointestinal nonvariceal and variceal bleeding, including the risk stratification, transfusion and coagulation management as well as the initial pharmacological treatment. In addition, current developments in endoscopic and interventional treatment of gastrointestinal bleeding are highlighted.
