The overall prevalence of EGJOO is unclear. The prevalence of EGJOO among all patients undergoing high resolution manometry was up to 10 percent. The diagnostic criteria were later adjusted to distinguish relevant (symptomatic) EGJOO from isolated manometric findings of EGJOO without symptoms. Individuals diagnosed with EGJOO based on Chicago 3.0 classification have an average age of 56–57 years. EGJOO more commonly affects women (51-88%). The average BMI is between 25 and 30.
