Overview

• Barrett's esophagus can be seen in younger patients, but is most commonly diagnosed in patients ~ 55 years old.

Epidemiology and Demographics

• This can be seen on EGD (esophago-gastroduodenoscopy) in ~ 1 % of all patients, but in up to 20 % of those with symptoms of GERD (Gastroesophageal Reflux Disease). Although the diagnosis can be presumed during the EGD, it needs to be confirmed by biopsy.
• It is more common in caucasians, than blacks or Asians. The prevalence in hispanic population is unclear, some studies compare it to caucasian prevalence and other studies show a lower prevalence.
• It is an acquired condition, seen in children but rarely in younger than age of five.
• More common in male, with a male to female ratio of 2:1.
