It’s one of the most common chronic infections in the world according to the CDC—and most people living with it don’t even know they have it. Helicobacter pylori (H. pylori) is a helix-shaped bacterium that lives in the mucus lining of the stomach and small intestine. It can cause peptic ulcer disease and is associated with mucosa-associated lymphoma and gastric adenocarcinoma. Though the infection is likely present in more than half of the population, the majority never show symptoms.
Patients that do present with signs and symptoms will require testing for presence of an active H. pylori infection.
