Chronic gastritis is not atrophic gastritis, and our country categorizes chronic gastritis into chronic non-atrophic gastritis, chronic atrophic gastritis, and special types of gastritis. Chronic non-atrophic gastritis, i.e., chronic superficial gastritis, is the early stage of chronic gastritis, which is usually manifested as chronic atrophic gastritis in the later stage. It should be noted that if chronic gastritis occurs, life, diet is still not pay attention to, then the condition will continue to develop, chronic atrophic gastritis may occur, and chronic atrophic gastritis, if not treated in time, may occur in the intestinal epithelium of metaplasia, for a kind of pre-cancerous lesions, and if not intervened in time, it will eventually develop into gastric cancer.
