Overall, gastritis is not considered a serious disease, but the severity of the disease is relative. There are many types of gastritis, and in general there are two main types: chronic non-atrophic gastritis and chronic atrophic gastritis. When chronic non-atrophic gastritis can be accompanied by erosion and reflux, it is relatively easy to treat. If it gets to the point of atrophy, it can be very troublesome to treat. The reason is that atrophic gastritis itself is precancerous, and there are no specific drugs in western medicine, so it is usually treated symptomatically. The malignancy rate of atrophic gastritis is relatively low, but if combined with heterogeneous hyperplasia, the malignancy rate will be very high; the malignancy rate is proportional to the degree of atrophy and heterogeneous hyperplasia, that is, the more severe the atrophy and the heavier the degree of heterogeneous hyperplasia, the higher the malignancy rate will be, which is very dangerous and can be easily transformed into gastric cancer.
