Chronic superficial gastritis can be categorized into mild, moderate and severe chronic superficial gastritis according to the depth of inflammatory cell infiltration. Chronic superficial gastritis is defined as chronic gastritis not accompanied by atrophic changes in the gastric mucosa, chronic superficial gastritis accounts for about 70% of chronic gastritis. Its pathogenesis is mainly related to Helicobacter pylori infection, aspirin, indomethacin and other non-steroidal anti-inflammatory drugs, bile, pancreatic fluid, intestinal fluid and other digestive fluids stimulation, alcohol, tobacco stimulation and so on. Clinically, according to the depth of infiltration of inflammatory cells into the mucosal layer can be divided into mild, moderate, and severe. Mild refers to inflammation infiltration to within 1/3 of the superficial mucosal layer, moderate refers to inflammation infiltration depth of 2/3, and severe refers to inflammation infiltration depth of more than 2/3 or the whole layer with cellular densification. Chronic superficial gastritis patients diet should avoid spicy stimulation, too cold and too hot food, moderate rest, work and rest, if necessary, medication, treatment under the guidance of a doctor.
