What percentage of people get a hiatal hernia?

Hiatal hernias are relatively common, especially as people age. It is estimated that about 60% of people over the age of 60 may have a hiatal hernia, though many of these cases are asymptomatic (meaning they don’t cause noticeable symptoms).

In the general population, the overall prevalence is estimated to be around 10-20%, but this can vary depending on factors such as age, obesity, and other health conditions like gastroesophageal reflux disease (GERD).

Key points about hiatal hernias:

  • Prevalence increases with age: The condition is more common in older adults.
  • Asymptomatic cases: Many people with a hiatal hernia may not experience symptoms, and the hernia may go unnoticed unless it causes complications.
  • Risk factors: Obesity, frequent coughing, heavy lifting, and pregnancy can increase the risk of developing a hiatal hernia.

Although the condition is common, not everyone with a hiatal hernia experiences symptoms, and many can manage the condition through lifestyle changes and medication if necessary.
