Chronic non-atrophic gastritis, commonly referred to as superficial gastritis, is persistent and can flare up acutely under certain triggers. Patients may experience nausea and vomiting, abdominal discomfort after eating, acid reflux and flatulence, etc., which can improve with symptomatic treatment. For young patients with non-atrophic gastritis, gastroscopy can be performed at the onset of gastric symptoms. However, clinically, for chronic non-atrophic gastritis over the age of 45, especially for people with high risk of gastric cancer such as combined Helicobacter pylori infection, family history of gastric cancer, high salt diet and smoking, it is recommended to review gastroscopy once in 1-2 years or so.
