 What Is Helicobacter pylori (H. pylori)?

H. pylori is a bacterium that can infect the stomach lining. It secretes a substance that neutralizes acid, thereby making the stomach a more hospitable place for the bacteria to grow. The infection increases the risk for gastric ulcers and ulcers in the small intestine. Years long inflammation may result in atrophic gastritis. Inflammation, ulcers and atrophic gastritis may predispose you to developing stomach cancer. A blood, stool or breath test can help diagnose H. pylori. People who currently have ulcers or who have a prior history of ulcers should be tested for the bacteria. Those who have a first-degree relative with gastric cancer should also be tested. The good news is that the infection responds to treatment with antibiotics.
