The term “celiac gastritis” refers to chronic gastritis in which the gastric mucosa undergoes celiac changes. The term “grade 3” may refer to the wide range of gastric mucosal erosion, and most hospitals do not grade celiac gastritis, and it is possible that grade 3 is the internal division of some hospitals. In the case of erosive gastritis, the inflammatory lesion is limited to the gastric mucosa and does not reach the muscular layer, so erosive gastritis is not considered a serious disease. If it is a more widespread foci of gastric mucosal erosion, it is called erosive gastritis, and if it is a scattered foci of erosion, such as punctate foci of erosion, it is called chronic gastritis with erosion. For the treatment of erosive gastritis, the main thing is to give acid suppressants combined with drugs that promote mucosal repair, such as oral omeprazole or lansoprazole and other proton pump inhibitors, combined with bismuth or rehabilitative new liquid, etc. The treatment effect is more ideal. For patients with erosive gastritis it is recommended to review the electronic gastroscopy at the end of the treatment to clarify whether the gastric mucosal erosion is completely cured, and if necessary, the course of treatment should be extended appropriately.
