Overview

Gastritis may be classified according to chronicity, into two categories: acute and chronic. Gastritis may also be classified by pathology/pathophysiology into subtypes by proposed classification systems such as the updated Sydney system [*REF] or the Operative Link for Gastritis Assessment [OLGA] staging system [*REF].

Classification

  • Classification and grading of Gastritis based on the Updated Sydney System. [1]
Classification and grading of Gastritis: Updated Sydney System
Type of Gastritis Etiology Gastritis synonyms

  • Diffuse antral gastritis (DAG)
  • Chronic antral gastritis (CAG)
  • Interstitial - follicular
  • Hypersecretory
  • Type B*
