Chronic non-atrophic gastritis with erosions is defined as chronic non-atrophic gastritis with scattered mucosal erosions, which are seen as scattered punctate erosions or strips of erosions of the mucosa under the electrogastroscope. Chronic non-atrophic gastritis, also known as chronic superficial gastritis, is mostly caused by Helicobacter pylori infection of the stomach. It can be treated like chronic gastritis with acid suppressants, combined with gastric mucosal protectors, or with rehabilitation fluids to promote the repair of the eroded mucosa. If H. pylori infection is clearly present, H. pylori eradication therapy needs to be given under the guidance of a gastroenterologist, as appropriate. The current recommendation is quadruple therapy, which is PPI plus bismuth plus two antibiotics. If chronic gastritis with erosion is clearly present and not treated, there is a risk that the erosion may worsen, leading to ulcers, etc., so it must be taken seriously.
