Chronic gastritis is a chronic inflammation of the gastric mucosa.



Since 1992, chronic gastritis lesions are classified according to the Sydney system.[2]

Chronic H. pylori-associated gastritis[edit]

This is the most common form of chronic gastritis. Involvement tends to occur in either an antral-predominant or multifocal atrophic pattern. H. pylori infection is also associated with development of peptic ulcer disease, gastric adenocarcinoma, and gastric mucosa-associated lymphoid tissue (MALT) lymphomas.[3]


Many people who have chronic gastritis do not experience any noticeable symptoms. Those who do claim to experience one or several of the following: upper abdominal pain, indigestion, bloating, nausea, vomiting, belching, loss of appetite, and weight loss. Stomach bleeding or black stool has been reported in extreme cases.[4]
