Chronic atrophic gastritis, compared to chronic non-atrophic gastritis, is relatively more severe. It is usually due to the atrophy of the gastric mucosal glands that this condition occurs. Under gastroscopy, the gastric mucosa can be seen to become pale, and the submucosal blood vessels are easily exposed. Sometimes, the gastric mucosal cells are replaced by intestinal epithelial cells, which is what we refer to as intestinal metaplasia. Some believe that this condition is a precancerous lesion, so it must be given sufficient attention. Firstly, it is necessary to check for Helicobacter pylori infection; if present, comprehensive antibiotic treatment is required. Some believe that if Helicobacter pylori is completely eradicated, partial reversal of gastric mucosal atrophy can happen, and in some cases, it may even return to normal, making the eradication of Helicobacter pylori particularly important. If there is no Helicobacter pylori infection, symptomatic treatment is advocated, such as protecting the gastric mucosa, etc. Additionally, traditional Chinese medicine has relatively better effects in treating atrophic gastritis compared to Western medicine, and further diagnosis and treatment in a traditional Chinese medicine department can be considered. (Note: The use of medications should be under the guidance of a professional doctor.)
