non-atrophic gastritis
(non-ay-TROH-fik gas-TRY-tis)
A condition marked by inflammation of the inner lining of the stomach. It is usually caused by an infection with the bacterium H. pylori that continues or worsens over a long period of time. Non-atrophic gastritis can lead to atrophic gastritis (thinning of the lining of the stomach caused by long-term inflammation) and certain types of stomach cancer.
