Chronic gastritis does not have specific symptoms, and the severity of the symptoms does not necessarily correspond to the severity of the disease. Common symptoms include pain in the upper middle abdomen, belching, acid reflux, nausea, vomiting, heartburn, a feeling of fullness after eating, poor appetite, and indigestion. In severe cases of atrophic gastritis, patients may experience symptoms such as anemia and weight loss. Some patients may also experience psychological symptoms such as anxiety and depression. If a patient experiences the above symptoms, it is recommended to promptly conduct a gastroscopy to confirm the diagnosis. It is also advisable to conduct a carbon-14 breath test to determine the presence of Helicobacter pylori infection, as this infection is a major cause of chronic gastritis. After confirming the diagnosis, appropriate treatment should be administered.
