Non-atrophic erosion should refer to non-atrophic gastritis with erosion, which is a type of chronic gastritis. Chronic non-atrophic gastritis is actually the former chronic superficial gastritis, which means that the mucosal epithelium of the gastric glands is not atrophic, which means that the gastritis is relatively mild. The acute inflammation of the gastric mucosa is referred to as erosion, which means that the surface of the gastric mucosa is broken, but the breakage is not very serious without the formation of ulcers. The cause is often related to the consumption of irritating food, H. pylori infection, taking non-steroidal anti-inflammatory drugs such as aspirin enteric tablets, etc. Its treatment is curable and generally not cancerous. For non-atrophic gastritis with erosion caused by H. pylori infection, anti-H. pylori treatment can be used. For non-atrophic gastritis with erosion caused by taking drugs that damage the gastric mucosa, it can be completely relieved and cured after stopping the drugs or taking gastric mucosal protection treatment. Patients should pay attention to their diet and lifestyle habits, and timely and regular treatment can lead to a cure.
