Gastritis is generally divided into two main categories: chronic non-atrophic gastritis and chronic atrophic gastritis. It is usually diagnosed by gastroscopy, and the treatment plan is determined based on the presence or absence of Helicobacter pylori infection. Also, it is necessary to develop good eating habits. It is important to eat on a regular schedule with controlled portions or small, frequent meals, and chew slowly and thoroughly. Try to avoid binge eating or extreme hunger or fullness. For staple foods, soft rice or noodles are generally recommended, accompanied by fresh vegetables, etc. As for meat, it should be prepared in a light and easy-to-digest manner during cooking, and it is best to avoid too raw, greasy, spicy, or stimulating foods. Additionally, maintaining a good mood can also be helpful.
