Overview
Hiatus hernias affect around 1 to 20% of the population. out of these 9% are symptomatic, depending on the ability of the lower esophageal sphincter (LES). 95% of these categorise under "sliding" hiatus hernias, in which the lower esophageal sphincter protrudes above the diaphragm along with the stomach, and only 5% are the "rolling" type (paraesophageal), in which the LES remains stationary but the stomach protrudes above the diaphragm. 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]
Case-fatality rate/Mortality rate
- In [year], the incidence of [disease name] is approximately [number range] per 100,000 individuals with a case-fatality rate/mortality rate of [number range]%.
- The mortality rate of elective paraesophageal hernia repair is approximately 1.4 percent.[2]
Age
- Patients of all age groups may develop [disease name].
- The incidence of [disease name] increases with age; the median age at diagnosis is [#] years.
- [Disease name] commonly affects individuals younger than/older than [number of years] years of age.
- [Chronic disease name] is usually first diagnosed among [age group].
- [Acute disease name] commonly affects [age group].
Race
- There is no racial predilection to [disease name].
- [Disease name] usually affects individuals of the [race 1] race. [Race 2] individuals are less likely to develop [disease name].
Gender
- [Disease name] affects men and women equally.
- [Gender 1] are more commonly affected by [disease name] than [gender 2]. The [gender 1] to [gender 2] ratio is approximately [number > 1] to 1.
Region
- The majority of [disease name] cases are reported in [geographical region].
- [Disease name] is a common/rare disease that tends to affect [patient population 1] and [patient population 2].
