Abstract
Helicobacter pylori infection exerts diverse effects on gastric physiology. It may increase gastric acid secretion, reduce it or result in no overall change in acid output1. The disturbance in acid secretion is related to the pattern of gastritis induced by the infection (Figure 1). In subjects with an antral-predominant non-atrophic H. pylori gastritis, acid secretion is normal or increased. This is the pattern of gastritis seen in patients who develop duodenal ulceration. In other subjects it produces an atrophic pangastritis or body-predominant gastritis. This results in markedly reduced acid secretion or achlorhydria and is seen in patients who develop non-cardia gastric cancer.
