Chronic gastritis includes two types: chronic non-atrophic gastritis and chronic atrophic gastritis. Chronic atrophic gastritis is generally more severe than chronic non-atrophic gastritis and usually accompanies intestinal metaplasia, which some refer to as a precancerous lesion. If chronic atrophic gastritis is present, formal medical treatment is necessary. Initially, it is advisable to check for Helicobacter pylori infection. If an Helicobacter pylori infection is found, timely eradication therapy is recommended, typically using quadruple therapy, which consists of a proton pump inhibitor, two types of antibiotics, and a bismuth agent. If there is no Helicobacter pylori infection, treatment generally focuses on symptomatic relief, such as protecting the gastric mucosa and enhancing gastric motility. Additionally, traditional Chinese medicine has shown satisfactory effects in treating chronic atrophic gastritis. It is also important to maintain good dietary and living habits, prefer light and easily digestible foods, and avoid raw, greasy, spicy, and irritating foods to help maintain a positive state of mind. Regular gastroscopy check-ups are necessary. (Medication should be taken under the guidance of a doctor.)
