More than 90 percent of duodenal ulcers are caused by the bacterium Helicobacter pylori and about two-thirds of the world’s population are infected with this. However, most of those infected do not show symptoms.
The absolute incidence of duodenal ulcers is not known, but the most recent estimates suggest that around 10 percent of a population will have evidence of this type of ulcer at some time in their lives.
The peak incidence of gastric ulcer is in the 60s, around 10 years later than for duodenal ulcer. They are slightly more common in men.
