Who is affected by gastroesophageal reflux disease (GERD)

It's hard to know how many people have GERD because so many people treat their symptoms at home without ever seeing a doctor. But heartburn is very common.1

  • About 4 out of 10 adults in the United States have heartburn at least once a month. About 2 out of 10 adults in the United States have heartburn at least once a week.1 Most of these people treat themselves and do not have complications.
  • Less than 1 out of 10 adults have heartburn and/or reflux on most days.2
  • Up to 80% of pregnant women have heartburn nearly every day.1 This heartburn usually goes away after the baby is born.
