What is Helicobacter pylori (H. pylori)？
Named for its spiral shape, Helicobacter pylori (H. pylori) is a kind of bacteria that can live in the stomach. By secreting enzymes that neutralise the acidity of gastric acid, H. Pylori can survive in highly acidic environments while parasitising on the surface of the human gastric mucosal layer or in the duodenum without getting killed. Some of the substances secreted by H. pylori will further damage the protective function of the gastric mucosa and stimulate more gastric acid secretion in the stomach, thereby inducing gastritis, gastric ulcer, duodenal ulcer, and even gastric cancer. The International Cancer Research Agency has also listed H. pylori as a Class I carcinogen.
