Gastritis: Pathophysiology and Clinical Manifestations
This medical illustration contrasts normal gastric anatomy with pathological changes observed in gastritis. The diagram emphasizes structural alterations affecting various layers of the stomach wall and associated complications.
Anatomical Structures and Pathological Changes
Esophagus Muscular tube lined with stratified squamous epithelium. Contains lower esophageal sphincter maintaining pressure of 15-25 mmHg.
Stomach Secretes HCl (pH 1-2) and pepsinogen through parietal and chief cells. Produces 2-3L gastric juice daily.
Duodenum First portion of small intestine receiving pancreatic enzymes and bile. Maintains pH 6-7 through bicarbonate secretion.
Ulcer Mucosal defect extending through muscularis mucosa. Often associated with H. pylori infection (CLO test sensitivity 90-95%).
Serosa Outer peritoneal layer containing lymphatics and blood vessels. Provides structural support and inflammatory response.
Damaged Stomach Lining Inflammation affects surface mucous cells and gastric glands. Reduced prostaglandin E2 synthesis compromises mucosal defense.
Clinical Management of Gastritis
H. pylori eradication requires triple therapy (PPI + two antibiotics). Success rates >90% with 14-day regimen.
Gastric acid suppression achieved through PPI therapy. Maintains intragastric pH >4 for optimal healing.
Endoscopic surveillance necessary for intestinal metaplasia. Sydney system guides biopsy sampling protocol.
Biomarkers include pepsinogen I/II ratio and gastrin-17. Serological testing aids risk stratification.

Modern gastritis management integrates molecular diagnostics with targeted therapies. This approach optimizes treatment outcomes and reduces complications.
Evidence-based protocols continue evolving with improved understanding of gastric pathophysiology. Early intervention prevents progression to more severe conditions.
