For patients with atrophic gastritis, it is recommended to adjust the diet, avoid spicy and stimulating foods, avoid overeating, and eat more fresh high-protein foods, which can significantly improve the atrophy of the gastric mucosa cells. The use of folic acid, gastric fuchsin, celecoxib or moroxydine is also recommended to improve the atrophy of the gastric mucosa and intestinal metaplasia.
