Also known as: Helicobacter Pylori
Helicobacter pylori (H. pylori) is a type of bacteria that infects the digestive system. Many people with H. pylori will never have symptoms of infection. But for others, the bacteria can cause a variety of digestive disorders. These include gastritis (inflammation of the stomach), peptic ulcers (sores in the stomach, small intestine, or esophagus), and certain types of stomach cancer.
