Etiology
Classification
Since 1992, chronic gastritis lesions are classified according to the Sydney system.
Chronic H. pylori-associated gastritis
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.
Symptoms
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.
