Patients with H pylori–associated gastritis may have antral-predominant inflammation or corpus-predominant gastritis. Corpus-predominant gastritis leads to hypochlorhydria (low levels of stomach acid) and predisposes individuals to gastric ulceration and adenocarcinoma. Antral-predominant inflammation leads to increased acid production from the uninflamed corpus and predisposes individuals to duodenal ulceration.

Gastritis caused by H pylori decreases somatostatin levels, which negatively affects gastrin secretion.

H pylori is the leading cause of chronic gastritis and the principal etiologic agent for gastric cancer and peptic ulcer disease.
