Gastritis is probably the most common among all digestive system diseases, including chronic non-atrophic gastritis and chronic atrophic gastritis. The treatment for gastritis mainly depends on the cause and specific symptoms. First, it is necessary to determine the treatment plan based on whether there is a Helicobacter pylori infection. If there is a Helicobacter pylori infection, the general treatment is quadruple therapy, which is an antibacterial treatment. If there is no Helicobacter pylori infection, treatment usually focuses on symptomatic relief such as suppressing stomach acid, protecting the gastric mucosa, and enhancing gastric motility, among others. Gastritis caused by other factors, such as inappropriate diet, emotional issues, or medications, etc., can usually be alleviated by adjusting the diet, relaxing, and discontinuing the relevant medications. (Medication use should be conducted under the guidance of a professional doctor.)
