Whether hospitalization is needed for chronic gastritis depends on the specific condition of the patient. If symptoms are mild, without proliferative ulcers, and clinical manifestations are not severe, symptoms can be improved through dietary adjustments and oral medications that inhibit gastric acid secretion and protect the gastric mucosa; these cases generally do not require hospitalization. However, if there is a confirmed Helicobacter pylori infection accompanied by nausea, stomach pain, and other digestive discomforts, and gastroscopic examination reveals atypical hyperplasia or intestinal metaplasia of the gastric mucosa, these situations necessitate active treatment in a hospital setting. (Medication should be used under the guidance of a doctor according to specific circumstances.)
