gastric erosion gastric erosion gastric erosion occurs when the mucous membrane lining the stomach becomes inflamed. specifically, the term "erosion," in this context means damage that is limited to the mucosa (which consists of three distinct layers: the epithelium (in the case of a healthy stomach, this is non-ciliated simple columnar epithelium), basement membrane, and lamina propria). an erosion is different from an ulcer. an "ulcer" is an area of damage to the gastrointestinal wall (in this case the gastric wall) that extends deeper through the wall than an erosion (an ulcer can extend anywhere from beyond the lamina propria to right through the wall, potentially causing a perforation). see gastrointestinal wall. some drugs, as tablets, can irritate this mucous membrane, especially drugs taken for arthritis and muscular disorders, steroids, and aspirin. a gastric erosion may also occur because of emotional stress, or as a side effect of burns or stomach injuries. see acute gastritis. symptoms there is basically one symptom of gastric erosion: bleeding from the area where the stomach lesion is. bowel movements may contain blood. vomit may be bloody as well, but a gastric erosion may not cause vomiting. blood may be black because it will be partially digested. loss of blood may cause one to develop anemia. risks anemia and other problems related to blood loss may occur. sometimes a person with a gastric erosion will experience severe bleeding all at once; red (bloody) vomiting and/or black bowel movements may occur. sources "gastric erosion." encyclopædia britannica, micropaedia. encyclopædia britannica inc., 1998 ed. this article is issued from wikipedia. the text is licensed under creative commons - attribution - sharealike. additional terms may apply for the media files.
