Gastric ulcers refer to ulcerative lesions on the gastric mucosa and are very common in gastroenterology. Typical symptoms include pain in the upper abdomen, often presenting as dull pain or a burning sensation in the early stages. Particularly after eating, pain in the upper abdomen occurs within an hour and gradually eases after two hours. As the condition progresses, complications such as gastric bleeding and gastric perforation may occur. Diagnosis can be confirmed clinically through a barium meal examination and gastroscopy. Currently, with the development of internal medicine drugs, most gastric ulcers can be treated with medication.
