Chronic gastritis

Contributor(s): Ed Hall, Philip K Nicholls, Kenneth Simpson

Introduction

  • Chronic inflammatory changes in gastric mucosa with concurrent signs of gastric disease.
  • Cause: damage to gastric mucosal barrier allows back-diffusion of acid leading to further mucosal damage.
  • Signs: vomiting.
  • Diagnosis: histopathology (gastric mucosa).
  • Treatment: eliminate underlying cause, dietary manipulation, H2 antagonists, anti-emetics.
  • Prognosis: good if underlying cause treated.

Pathogenesis

Etiology

Pathophysiology

  • Damage to gastric mucosal barrier   →   allows back-diffusion of gastric acid and pepsin   →   local inflammation extending deeper   →   degranulation of enterochromaffin-like cells in submucosa and lamina propria   →   histamine stimulates further production of hydrochloric acid   →   further mucosal damage.

Timecourse
