Non-atrophic gastritis with erosive lesions, primarily diagnosed through gastroscopic examination that revealed erosive and other changes in the gastric mucosa.

If erosion is detected, doctors generally perform a biopsy under gastroscopy to ascertain the nature of the erosion. If the erosion is inflammatory, it can be treated with oral medications, including acid-suppressing and stomach-protective drugs, promoting gastric motility, and protecting the gastric mucosa. If the erosion involves intestinal metaplasia or atypical hyperplasia, it requires endoscopic APC treatment or endoscopic submucosal dissection (ESD) to eliminate the erosive areas, thereby addressing the erosion fundamentally. Additionally, attention should be paid to a light and easily digestible diet.
