Common symptoms of chronic atrophic gastritis include upper abdominal distension, belching, acid reflux, nausea, vomiting, postprandial fullness, heartburn, and indigestion. Gastroscopy can reveal atrophy of the gastric glands in the mucosa, and a definitive diagnosis of chronic atrophic gastritis can be made through biopsy and histopathological examination. In terms of treatment, the first step involves eradicating Helicobacter pylori, using a regimen that includes a proton pump inhibitor, two antibiotics, and a bismuth agent, over a 14-day treatment period. Additionally, treatments aimed at acid suppression, gastric motility enhancement, and gastric mucosal protection are also necessary. Traditional Chinese medicine can also be effective in treating atrophic gastritis. A combined approach utilizing both Western and Chinese medicine can yield better outcomes for the treatment of atrophic gastritis.
