What is 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 , basement membrane, and lamina propria]. An erosion is different from an ulcer. An "ulcer" is an area of damage to the gastrointestinal wall that extends deeper through the wall than an erosion. 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.
