Where are ulcers more commonly located in the stomach?

Ulcers are more commonly located along the lesser curvature of the stomach. This area is particularly susceptible due to the presence of acid secretion and the proximity to the gastric outlet, which affects gastric motility and may contribute to ulcer formation. The lesser curvature has a unique blood supply and mucosal defenses, making it a favorable site for the development of ulcers, especially in the context of Helicobacter pylori infection and the use of nonsteroidal anti-inflammatory drugs (NSAIDs).

While ulcers can occur in other regions of the stomach, such as the body or pylorus, the lesser curvature consistently shows a higher prevalence in clinical studies. The greater curvature, although it can develop ulcers, generally has a lower incidence compared to the lesser curvature due to differences in anatomical and physiological factors. Understanding these locations helps in diagnosing and managing gastric ulcers effectively.
