What is an H. pylori infection?

ANSWER

A common kind of bacteria called Helicobacter pylori, or H. pylori, can cause an infection in your stomach that sometimes leads to ulcers. It also can raise your risk of stomach cancer. At least half the people in the world get it at some point, usually in childhood. Doctors aren't sure why it affects some people differently than others.
