Overview
Hiatus hernias affect around 1 to 20% of the population. out of this 9 % are symptomatic, depending on the ability of the lower esophageal sphincter (LES). 95% of these categorize under "sliding" hiatus hernias, in which the lower esophageal sphincter protrudes above the diaphragm along with the stomach, and only 5% is the "rolling" type (paraesophageal), in which the LES remains stationary but the stomach protrudes above the diaphragm. A hiatus hernia is more common in older people.
Epidemiology and Demographics
Prevalence
- The prevalence of type I hiatus hernia in the adult population in North America is approximately 10 to 80 percent.[1]
- It is estimated that greater than 95 percent of hiatus hernias are type I (sliding) hiatus hernia.
- Approximately 5 percent of the haital hernias are with type II, III, and IV (paraesophageal) hernias.
Mortality rate
Age
- Hiatus hernias commonly affects individuals older than 50 years of age.
Race
- There is no racial predilection to hiatus hernia.
Gender
- women are more commonly affected by Hiatus hernias than men.
