Information and Treatment

What is H. Pylori?

Helicobacter pylori – or H. pylori is a type of bacteria that causes a chronic infection of the stomach – usually during childhood. A common cause of stomach and duodenal ulcers, H. pylori infection may be present in more than 50% of people – though most people don’t realize they have the infection, because they never get sick from it. If you develop signs and symptoms of a peptic ulcer, your doctor will test you for H. pylori infection with a breath test or upper endoscopy/EGD. H. pylori is a carcinogen and contributes to the development of stomach cancer.


Symptoms of H. pylori infection include:

  • Ache or burning pain in your abdomen
  • Abdominal pain on an empty stomach
  • Nausea
  • Loss of appetite
  • Unintentional weight loss
  • Dark stools
  • Anemia
