Complications
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). About 10% of people with H. pylori will develop an 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.
