What department should I register for a stomach examination?

When a stomach examination is required, you can register at the following departments: 1. **Gastroenterology**: This department primarily deals with diseases of the digestive organs, such as the esophagus, stomach, and duodenum, including conditions like gastritis and gastric ulcers. Gastroenterology offers various diagnostic tests, such as gastroscopy and Helicobacter pylori detection, to confirm diagnoses. 2. **Gastrointestinal Surgery**: If the stomach condition requires surgical treatment, such as gastric tumors or gastric perforation, you should visit the Gastrointestinal Surgery department. 3. **General Internal Medicine**: In hospitals where the medical specialties are not highly细分 or where there are no dedicated gastroenterology or gastrointestinal surgery departments, you can opt for gastric-related examinations at the General Internal Medicine department.
