Vomit is dark brown may be due to erosive hemorrhagic gastritis, peptic ulcer, esophageal cardia mucosal tear syndrome and other causes.
1. Erosive hemorrhagic gastritis: it is an acute gastritis mainly characterized by erosion and bleeding of the gastric mucosa, which is one of the important causes of gastrointestinal bleeding, and the blood itself is bright red, but under the action of gastric acid, it will become dark brown.
2. Peptic ulcer: when the patient has a large amount of bleeding from the ulcerated surface of the stomach, he may vomit dark brown material, but the ball ulcer vomits less dark brown material, and the clinical manifestation is mainly in the form of black stool.
3. Esophageal cardia mucosal tear syndrome: Due to severe and frequent nausea or vomiting, the intra-abdominal pressure increases suddenly, causing the mucous membrane or submucous layer of the distal esophagus or cardia to be torn, resulting in upper gastrointestinal bleeding, and the symptom of dark brown vomit will appear.
Vomit is dark brown may also be caused by other reasons, if the vomit is dark brown, should go to the hospital in time to see a doctor, clear the cause and give standardized treatment.
