The main cause of chronic atrophic gastritis with moderate intestinal metaplasia is the atrophy of the mucosal epithelium and glands, which leads to the thinning of the mucosa and the thickening of the mucosal muscle layer, so that the metaplasia of the intestinal epithelium appears. For atrophic gastritis with intestinal metaplasia, it is recommended to pay attention to the diet, which must be reasonably diversified, and to consume more fresh foods with high protein, which can promote the change and recovery of the atrophic cells. In terms of treatment, you can mainly give folic acid, gastric rejuvenation, celecoxib or Morodan, etc. However, the treatment course for chronic atrophic gastritis with moderate intestinal metaplasia is usually longer, and you also need to pay attention to regular review of gastroscopy and H. pylori, if H. pylori positive, you need to actively anti-H. pylori treatment.
