• Overview

    A peptic ulcer is a sore in the lining of the bowel in the stomach or the upper part of the small intestine (duodenum). The ulcer causes pain and can be quite debilitating.

    It is estimated 8 to 10 million people are infected with H. pylori. The proportion of people with this infection increases considerably with age. About 10-20% of infected adults will develop ulcers. In First Nation communities, approximately 75% of the people are infected. H. pylori infection is considered to be a carcinogen by the World Health Organization (WHO) as it is associated with the development of stomach cancer.

    A peptic ulcer is a sore in the lining of your stomach or upper part of your small intestine (duodenum). 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).
