Atrophic gastritis is a common type of benign chronic inflammatory disease. There are three major classes of drugs commonly used to treat atrophic gastritis: the first class, antibiotic drugs, commonly used are clarithromycin and amoxicillin. The second category, acid-suppressing drugs, commonly used are omeprazole and ranitidine. The third category, drugs to protect the gastric mucosa, is represented by membrane Gustar. Treatment by combining these three types of drugs needs to be accompanied by regular dietary treatment. No spicy and irritating food, no boiling hot food, no overeating, and easy-to-digest food should be eaten, and the best treatment effect can be achieved by combining with medication.
