It is bleeding in the upper part of the digestive tract, which runs from the oesophagus to the first portion of the small intestine (duodenum).
The most common causes are gastric or duodenal ulcers.
It manifests with vomiting of blood and/or tar-coloured, pasty stools. It may be accompanied by skin pallor, tachycardia, hypotension and a significant feeling of tiredness.
It is diagnosed by a complete medical history, physical examination, blood tests and digestive endoscopy.
The first objective of hospital treatment is to stabilise blood pressure by administering blood and/or saline. Any alteration of the blood coagulation components must be corrected. If delayed, digestive endoscopy should be performed to directly treat the site of bleeding.
