Bacterial infection of the gastrointestinal system, commonly that of H. Pylori can also cause gastritis. H. pylori bacteria are the most common causes of gastritis. It accounts roughly to 90% of cases. This bacterium infects the stomach lining. The infection is also passed from one person to the other and also to the persons through contaminated food or water. If this occurs in childhood and continues to cause problems in adulthood, the bacterium becomes the chief cause of chronic gastritis also.
