大面积胃出血，最好用术语“腐蚀”表示，是由于表面黏膜腐蚀脱落引起的。病理过程术语为胃病, 描述胃黏膜损害并不伴有明显的炎症。图示急性侵蚀性胃炎，当然也有其它类型。各种胃病的病因包括：酒精，药物，例如NSAIDS（非类固醇类抗炎药），应激，尿毒症，胆汁逆流，门脉高压症，放射线，和化疗。
Here are some larger areas of gastric hemorrhage that could best be termed "erosions" because the superficial mucosa is eroded away. Such erosions are typical for the pathologic process termed gastropathy, which describes gastric mucosal injury without significant inflammation. The findings here fit with acute erosive gastropathy, but there are other patterns. Etiologies for the various gastropathies can include: alcohol, drugs such as NSAIDS, stress, uremia, bile reflux, portal hypertension, radiation, and chemotherapy.
