Mild atrophic gastritis has a chance of being completely cured after standardized treatment, while moderate to severe atrophic gastritis cannot be completely cured. Atrophic gastritis belongs to one of the categories of chronic gastritis, and is most commonly caused by Helicobacter pylori infection, so once found to be positive for Helicobacter pylori need to carry out a four-pronged program of eradication, such as omeprazole + Clarithromycin + Amoxicillin + Bismuth Potassium Citrate. If atrophic gastritis is mild and there is no intestinal epithelial hyperplasia or heteroplasia, there is a possibility of complete cure after standardized treatment. If the gastritis has reached middle or severe atrophic gastritis, it is difficult to be cured completely, in which the degree of gastric mucous membrane atrophy is more serious, and may be accompanied by intestinal epithelial growths and heteroplasia, which is difficult to be reversed to achieve the state of complete cure. The use of medication should be carried out under the guidance of a doctor, and should not be used without authorization.
