The exact prevalence of hiatus hernia is unclear due to the differences in diagnostic criteria (1).

  • thought to be uncommon in the far East
  • in the adult population in North America, the prevalence rate varies between 10% to 80%
  • however it is believed to be similar to the prevalence of obesity
  • prevalence is also thought to be increasing with age
    • 30% of the population over 50 yrs are thought to have a hiatus hernia. (1,2,3)

Frequency of hiatus hernia is reported to be higher in Western population e.g. – in Norway 16.6% of 670 subjects, in USA 22% of 293 subjects, and in Sweden 14.5% of 1000 subjects who underwent upper gastro intestinal endoscopy were found to have hiatus hernia (3)

90% of patients with marked oesophagitis have a hiatus hernia.
