How do you know if you have an H. pylori infection?

ANSWER

If your doctor thinks you may have an H. pylori  infection, they may do one or more of these:

  • The best way to test for H. pylori infection is to check your stomach lining. Your doctor will give you medicine to relax you, then send a long, thin tube with a camera on the end down your throat and into your stomach. They'll look for signs of infection and take a small sample of tissue to be tested in a lab.
  • A blood test can show signs of H. pylori.
  • Your doctor can test your poop for signs of H. pylori.
