Chronic gastritis has many symptoms in clinical practice, but there is no specificity. Most patients present with symptoms of indigestion such as pain in the upper abdomen, nausea, and acid reflux, which are related to the severity of chronic gastritis. In cases of atrophic gastritis, there is also abdominal pain. If the gastritis is caused by Helicobacter pylori infection, there may not be specific symptoms, just a feeling of fullness in the abdomen after eating. For chronic gastritis, gastroscopy and gastrointestinal barium meal examination can be performed, and treatment can be administered according to the type of gastritis.
