Chronic non-atrophic gastritis is also known as chronic superficial gastritis. It is a classification of chronic gastritis, which also includes chronic atrophic gastritis and special types of gastritis as other classifications. Chronic non-atrophic gastritis refers to a condition where the glands in the gastric mucosa do not show atrophy, thus it is called chronic non-atrophic gastritis. Generally, the endoscopic appearance of the gastric mucosa being hyperemic, edematous, or eroded can lead to a diagnosis of chronic non-atrophic gastritis. Treatment mainly focuses on acid suppression, protecting the stomach, promoting gastric motility, and protecting the gastric mucosa. If there is a positive Helicobacter pylori infection, eradication treatment for Helicobacter pylori is required. Patients with chronic non-atrophic gastritis should primarily consume a light and easy-to-digest diet.
