Common symptoms of chronic non-atrophic gastritis with erosion include upper abdominal bloating, belching, acid reflux, nausea, vomiting, poor appetite, indigestion, heartburn, etc. A gastroscopy can reveal symptoms like hyperemia, edema, and erosion on the gastric mucosa to diagnose chronic non-atrophic gastritis with erosion. It is also recommended to perform a Carbon-14 breath test to determine if there is an infection of Helicobacter pylori. If the infection is positive, a 14-day treatment for Helicobacter pylori is required, using a regimen of a proton pump inhibitor, two antibiotics, and a bismuth agent, with the course lasting 14 days. Additionally, treatment for chronic non-atrophic gastritis with erosion should include acid suppression, gastric protection, promoting gastric motility, and protecting the gastric mucosa, which typically requires about six weeks. With the above treatments, the disease can be cured.
