HELICOBACTER PYLORI OVERVIEW
Helicobacter pylori, also known as H. pylori, is a bacterium that is commonly found in the stomach. It is present in approximately one-half of the world's population.
The vast majority of people infected with H. pylori infection have no symptoms and will never develop problems. However, H. pylori is capable of causing a number of digestive problems, including ulcers, and, much less commonly, stomach cancer. It is not clear why some people with H. pylori get these conditions and others do not.
This article discusses the symptoms, testing, and treatment of H. pylori infections. Stomach ulcers, also known as peptic ulcers, are discussed separately.
