Chronic gastritis is relatively common in clinical settings and generally responds well to standardized treatment, so there is no need for excessive worry. As the name implies, chronic gastritis is caused by various factors that lead to inflammatory changes in the stomach, which may manifest as congestion and edema of the gastric mucosa, erosion, and even the formation of multiple superficial ulcers. Common symptoms of chronic gastritis include abdominal pain, bloating, nausea, and belching, usually with a long history. The abdominal pain typically occurs in the upper abdomen and is related to food intake, which may improve after eating. Nausea and vomiting generally involve gastric contents, sometimes including blood. Patients undergo gastroscopy and biopsy to further confirm chronic gastritis, and tests for Helicobacter pylori are commonly performed. If the treatment involves Helicobacter pylori and results are positive, treatment to protect the stomach and eradicate Helicobacter pylori is recommended.
