If you or someone you know is diagnosed with Helicobacter pylori, you're not alone. Consumer Reports Health can help with the best research about H. pylori, and expert evidence and advice about treatment options.

Key points for people with H. pylori
  • H. pylori, one of the many types of bacteria that can live in your body, is very common, but most people who have it don't get any symptoms.
  • If you have H. pylori, you're more likely to get indigestion or an ulcer.
  • H. pylori is just one cause of indigestion. Other causes of indigestion include spicy food, stress, overeating, hiatal hernia, aspirin, and alcohol.
  • Most people who have indigestion don't have an ulcer. But they may have painful swelling in their stomach or duodenum (the part of your gut just under your stomach).
  • If you have H. pylori, you're more likely to get stomach cancer, although this disease is rare.
  • Most people who have H. pylori got it when he or she was a child, but better living standards today mean that fewer children now catch the bug.
  • Treating H. pylori gets rid of the bug in about 9 in 10 people.
  • If an ulcer causes your indigestion, getting rid of H. pylori will usually cure your indigestion.
H. pylori is common in the United States. About one-half of Americans over the age of 60 have it, and about 1 in 5 under the age of 40 have it. Doctors discovered Helicobacter pylori about 20 years ago, and they are still learning how H. pylori is linked to digestion problems.

Today's treatments for H. pylori work very well and get rid of the bug in about 9 in 10 people. If you have a stomach ulcer or a duodenal ulcer and you're infected with H. pylori, getting rid of the bug should heal your ulcer and reduce the chances of it returning.
