Chronic atrophic gastritis with intestinal metaplasia often arises from untreated chronic superficial gastritis, primarily due to Helicobacter pylori infection. Therefore, it is essential to first check for Helicobacter pylori infection. If an infection is present, quadruple therapy is generally used to eradicate the bacteria, which may improve the atrophy. If there is no Helicobacter pylori infection, treatment mainly involves protecting the gastric mucosa. While there are no specific Western medicines for this, traditional Chinese medicine and a differential diagnosis approach often yield good results. Regular follow-ups are also important. (Specific medications should be used under the guidance of a doctor.)
