Overview

Gastritis must be differentiated from peptic ulcer disease, gastric cancer, gastroesophageal reflux disease (GERD), gastroenteritis, crohn's disease, gastrinoma, gastric adenocarcinoma and primary gastric lymphoma.

Differentiating Gastritis from other Diseases

Differentiating gastritis from other Diseases:
