Gastric ulcers are a common peptic ulcer disease caused by an imbalance of aggressive factors and gastric defense factors. Gastric ulcers can occur clinically in any part of the stomach, but are more likely to occur in the gastric horn and the lesser curvature of the gastric sinus. The main site of gastric ulcer is at the junction of the pyloric gland area and the gastric secretion gland area, close to the pyloric gland area, while the junction of the pyloric gland area and the secretion gland area will move up in the elderly, so the site of gastric ulcer is relatively higher in the elderly, and this is the location characteristic of gastric ulcer in the elderly.
