Helicobacter pylori (H. pylori) is a bacterium (germ) that lives in the inner lining of the stomach. It produces a number of chemicals that damage the lining of the stomach. Once the infection is present, it persists for many years, if not for life.
About 40% of persons over 60 years of age have Helicobacter pylori. Most people are infected in childhood and in Australia the risk of becoming infected is now much less than in the past. There is no difference in infection rate between men and women. H. pylori is more common in older people and in certain ethnic populations (e.g. Middle Eastern, Asian and eastern European).
