What is the connection between Helicobacter pylori bacteria and gastritis?
Gastritis is often caused by Helicobacter pylori bacteria, or H. pylori for short. More than 30% of the world's population is infected with H. pylori, making it one of the most common bacterial infections. These bacteria live deep in the mucus that coats the stomach lining. However, although long-term infection is known to cause gastritis in some people, it is also possible for others to carry H. pylori without ever developing symptoms. For this reason, other factors are also thought to play a role in making certain people more sensitive to developing H. pylori-related gastritis.
