Chronic gastritis is generally difficult to cure completely. The current treatment principle is to eliminate the cause, alleviate symptoms, and prevent or reduce the recurrence of the disease. Treatment mainly focuses on protecting the gastric mucosa, suppressing gastric acid secretion, and eradicating Helicobacter pylori infections. Post-treatment care is also very important. It is advisable to eat a diet that is light, soft, and easy to digest, avoid spicy, stimulating, and greasy foods, and steer clear of strong tea, coffee, and alcoholic beverages. Engaging in appropriate outdoor exercises and managing emotions also play a positive role in the treatment of chronic gastritis.
