Overview
A peptic ulcer is a sore in the lining of your stomach or upper part of your small intestine (duodenum). When the peptic ulcer is located in your stomach, it is called a gastric ulcer. For many years it was thought that stress or certain foods caused ulcers. It is now known that most ulcers are caused by a bacterium called Helicobacter pylori (H. pylori).
It is estimated 8 to 10 million people are infected with H. pylori. About 10-15% of infected adults will develop ulcers. In First Nation communities, approximately 75% of the people are infected.
