In the United States alone, one-third of the population is infected with H. pylori. There are 3.7 million cases of peptic ulcer disease (PUD) in the US annually. One in 10 Americans are at risk of developing PUD. The direct and indirect cost of PUD is estimated at $9.5 billion in the US.5,6

  • Most H. pylori bacteria are acquired during childhood and persist throughout life, if left untreated
  • The highest infection rates (3%-10%) are known to occur in developing countries. H. pylori transmission is more likely to happen within families and can possibly occur when the bacterium passes through vomit or stool
  • 80%-90% of all ulcers are caused by or associated with H. pylori 5
  • H. pylori  infection is associated with 70% of all gastric ulcers7
