Atrophic gastritis and atrophic gastric erosion do not mean the same thing; atrophic gastric erosion refers to the presence of gastric mucosal erosion based on atrophic gastritis. When atrophic gastritis is accompanied by gastric erosion, it is crucial to actively check for Helicobacter pylori infection. If the Helicobacter pylori infection tests positive, the treatment involves a two-week quadruple therapy that includes bismuth to eradicate Helicobacter pylori, along with medications to protect the gastric mucosa, such as magnesium carbonate, sucralfate, etc., and also some digestive aids. (Please take medication under the guidance of a doctor.)
