Upper abdominal pain caused by gastritis is usually due to excessive secretion of gastric acid, which irritates the gastric mucosa. In such cases, acid-suppressing medications are preferred, commonly including H2 receptor antagonists and proton pump inhibitors, with proton pump inhibitors being the first choice. Treatment plans should also be determined based on underlying diseases and the presence of Helicobacter pylori infection. If Helicobacter pylori infection is present, formal quadruple therapy should be initiated to eradicate the bacteria. If there is no infection, symptomatic treatment with proton pump inhibitors as the first choice is sufficient. Some patients may experience upper abdominal pain due to episodic gastric spasms. In such cases, antispasmodic pain relievers such as scopolamine butylbromide or anisodamine can be used for symptomatic treatment. It is also important to eat a light, easily digestible diet and to avoid exposure to cold. (Note: Please use medication under the guidance of a clinical doctor and based on specific circumstances.)
