Gastric and duodenal hemorrhage, blood through a few meters long intestine, various chemical changes, and gradually become black, therefore, these places bleeding, the amount is not very large, the stool should be black. In patients with upper gastrointestinal bleeding, about half of the bleeding due to ulcer disease, most of which is duodenal ulcer bleeding. In addition to ulcer disease, gastritis, cirrhosis with esophageal or gastric varices rupture, gastric cancer, is also a common cause of upper gastrointestinal bleeding.
