Gastric ulcers and duodenal ulcers are collectively known as peptic ulcers, formed under the self-digestion action of gastric acid and pepsin. Gastric ulcers are more common in middle-aged and elderly people, generally occurring at the lesser curvature of the stomach body. The pain of a gastric ulcer typically appears within an hour after eating, also known as postprandial pain, which gradually eases after one to two hours of digestion and absorption; gastric ulcers can easily lead to bleeding and perforation. Duodenal ulcers are more common in young and middle-aged adults, frequently occurring in the duodenal bulb. Typical symptoms include postprandial pain and midnight pain, which can be alleviated by using antacids. The treatment methods for gastric and duodenal ulcers are similar. Additionally, it is important to pay attention to diet in daily life, eat less spicy, greasy, and irritating food, and consume more soft, easily digestible food.
