Atrophic gastritis is a condition where the mucous membrane of the stomach atrophies, associated with poor neural nutrition and excessive gastric acid secretion, leading to a reduction in the barrier function of the gastric mucosa. To first alleviate pain, proton pump inhibitors can be used to reduce the secretion of gastric acid, and at the same time, gastric mucosal protectants should be used. If there is an infection with Helicobacter pylori, active use of triple or quadruple therapy should be employed to eradicate Helicobacter pylori. It is important to adjust one's diet, eat regularly, and avoid overeating. Greasy and spicy foods should be consumed less, and more bland, soft, and easily digestible foods should be eaten. (Please use medication under the guidance of a doctor.)
