Gastroscopy can be done once every 1-3 years for non-atrophic gastritis. Non-atrophic gastritis is a relatively common stomach disease. The inflammation of this disease is relatively superficial, so the damage to the patient is relatively mild, and most patients do not have the possibility of cancer, and the condition can be improved with medication. After gastroscopy, patients with non-atrophic gastritis can continue to undergo gastroscopy for about 3 years as long as the environment in the stomach is relatively good and no erosion exists, but some patients’ stomachs are not particularly good and there is erosion, so the frequency of examination for these people should be shortened and it is best to go to the hospital every year. After the discovery of non-atrophic gastritis, the disease should be treated as early as possible. Common therapeutic drugs include ranitidine and colloidal bismuth pectin.
