Gastritis is inflammation (irritation) of the stomach lining.

Common causes include infection, anti-inflammatory medication and alcohol.

Treatment options include avoiding exposure to known irritants and medication to reduce the amount of gastric juices.

Helicobacter pylori (H. pylori) is a bacterium (germ) that can infect the human stomach. The bacterium lives in the lining of the stomach, and the chemicals it makes inflame the stomach lining. Infection seems to be lifelong unless it is treated with medication to remove the bacterium. There are often no symptoms of the infection, but treating it lowers your risk of other more severe health problems.
