Complications associated with H. pylori infection include:

  • Ulcers. H. pylori can damage the protective lining of your stomach and small intestine. This can allow stomach acid to create an open sore (ulcer).
  • Inflammation of the stomach lining. H. pylori infection can irritate your stomach, causing inflammation (gastritis).
  • Stomach cancer. H. pylori infection is a strong risk factor for certain types of stomach cancer.
