There is no staging system for H pylori infection, but the following steps in the disease process are well described:

  • Chronic gastritis

  • Atrophic gastritis

  • Intestinal metaplasia: May evolve into dysplasia

  • Gastric adenocarcinoma: Consider ultrasonography and esophagogastroduodenoscopy (EGD) in patients with gastric MALTomas (mucosa-associated lymphatic tissue lymphomas) for more precise staging of the disease
