Chronic gastritis

Chronic gastritis
Classification and external resources
[]

Chronic gastritis is a chronic inflammation of the gastric mucosa.

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.

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.

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