Overview

Achalasia is an esophageal motility disorder characterized by incomplete lower esophageal sphincter relaxation.

Epidemiology and Demographics

Incidence and Prevalence

  • Achalasia is a rare disease, with an incidence of ~ 1 case per 100,000 per year in adults and a prevalence of 8-10 case per 100,000.[1][2][3]

Age

  • Onset can be at any age, however it is rare to be seen before adolescence, and is most commonly seen in people between 25 and 60 years old, mean age of diagnosis being > 50 years.[4]

Gender

  • Achalasia has no predilection to any age.[4][3]
