Duodenal ulcers are more common than which type of ulcers?

Duodenal ulcers are indeed more common than gastric ulcers. Both types of ulcers occur in the upper gastrointestinal tract, but they differ in their locations and causes. Duodenal ulcers are located in the first part of the small intestine, whereas gastric ulcers occur in the lining of the stomach.

Research and clinical observations have shown that duodenal ulcers are influenced by factors such as the presence of Helicobacter pylori infection and the secretion of gastric acid. The incidence of duodenal ulcers has been found to be higher due to these factors and the fact that the environment of the duodenum often allows an ulcer to develop more readily than in the stomach.

In contrast to gastric ulcers, which may be affected by existing stomach conditions such as chronic gastritis, the prevalence of duodenal ulcers is more significant in the general population, particularly among individuals with a history of peptic ulcers. This contextual understanding helps establish why duodenal ulcers are highlighted in comparison to gastric ulcers.
