Chronic gastritis can be divided into two main categories: chronic non-atrophic gastritis, which was previously referred to as chronic superficial gastritis, and chronic atrophic gastritis. The primary cause of chronic gastritis is generally considered to be Helicobacter pylori infection, which has a very high infection rate in our country, exceeding 50%. Moreover, inappropriate diet can also cause chronic gastritis, such as stimulation from smoking and drinking, irregular eating habits, overeating, as well as excessive consumption of raw, greasy, spicy, and other irritating foods. Additionally, emotional factors are closely related to chronic gastritis.
