hematemesis
Sign in to saveAlso known as haematemesis, vomiting of blood, spit blood
Hematemesis is the vomiting of blood. It can be confused with hemoptysis (coughing up blood) or epistaxis (nosebleed), which are more common. The source is generally the upper gastrointestinal tract, typically above the suspensory muscle of duodenum. 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. However, this is not found in stomach viruses (norovirus, rotovirus, etc.)

Hematemesis is the vomiting of blood. It can be confused with hemoptysis (coughing up blood) or epistaxis (nosebleed), which are more common. The source is generally the upper gastrointestinal tract, typically above the suspensory muscle of duodenum. 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. However, this is not found in stomach viruses (norovirus, rotovirus, etc.)
Hematemesis is treated as a medical emergency, with treatments based on the amount of blood loss. Investigations include endoscopy. Any blood loss may be corrected with intravenous fluids and blood transfusions. Patients may need to avoid taking anything by mouth.
