Atrophic gastritis negative generally means there's no major issue. A negative result for atrophic gastritis indicates that the patient is unlikely to have atrophic gastritis. In such cases, it may be considered that there is chronic superficial gastritis. If the patient has symptoms such as acid reflux, belching, heartburn, nausea, vomiting, etc., the use of proton pump inhibitors can be considered to suppress the secretion of stomach acid, and products such as aluminum magnesium carbonate and sucralfate to protect the gastric mucosa. Treatment to promote gastric motility such as Itopride or Mosapride can also be considered. Additionally, it is necessary to conduct a Carbon-13 urea breath test or Carbon-14 urea breath test to check for Helicobacter pylori infection.
