Patients with atrophic gastritis should be highly attentive if they experience significant weight loss and should receive standardized traditional treatments. Additionally, dietary habits also require careful attention; it is important to quit smoking and drinking alcohol, and to avoid using medications that damage the gastric mucosa, such as nonsteroidal anti-inflammatory drugs and steroids. Furthermore, eating habits should be regular, avoiding binge eating and foods that are too salty, spicy, or that are fried or deep-fried. Active treatment should also be directed against Helicobacter pylori, utilizing medications that protect the gastric mucosa, enhance its resistance to gastric acid, and improve the regenerative ability of gastric mucosal cells. Medications that inhibit bile reflux and improve gastric motility can also be employed.
