Patients with atrophic gastritis primarily exhibit symptoms such as dull pain, bloating, and burning pain in the upper abdomen, along with belching, acid reflux, weight loss, anemia, and more. If the pain from atrophic gastritis does not follow a clear pattern and is accompanied by progressive weight loss and refractory anemia, the possibility of cancerous changes in atrophic gastritis should be considered. It is advisable to promptly complete an endoscopy to confirm the diagnosis and rule out malignancy, and, if necessary, undertake a biopsy. In terms of treatment, it is first essential to test for Helicobacter pylori infection and then use medications to protect the gastric mucosa.
