The main symptoms of atrophic gastritis include upper abdominal pain, belching, acid reflux, poor appetite, nausea, vomiting, indigestion, etc., which are not specific compared to the symptoms of chronic superficial gastritis. Therefore, it is not possible to determine whether it is atrophic gastritis or superficial gastritis based solely on symptoms; a gastroscopy is necessary for a definitive diagnosis. If the gastroscopy reveals thinning of the gastric mucosa and atrophy of the gastric glands, atrophic gastritis can be confirmed. Additionally, if atrophic gastritis is suspected, a biopsy and pathological examination are also needed for a clear diagnosis. Regarding treatment, atrophic gastritis requires therapies such as anti-Helicobacter pylori treatment, acid suppression, promoting gastric motility, and protecting the gastric mucosa. Furthermore, it is recommended to combine traditional Chinese medicine differentiation-based treatment for better effects when used alongside Western medicine.
