From Libre Pathology. Reactive gastropathy, abbreviated RG, a relatively common pathology of the stomach. It is also known as chemical gastropathy, and incorrectly referred to as chemical gastritis (see below). NSAID gastropathy redirects to here.
Gastritis is an inflammation or irritation of the stomach lining and is associated with a variety of conditions. It develops when the stomach's powerful protective layer - the mucous-bicarbonate barrier - is overwhelmed and the stomach lining is exposed to the caustic gastric acids the body uses to break down food.
