Causes of Barrett's Esophagus
Age and Gender
The average age at diagnosis is 60, but it is usually difficult to determine when the problem started. It is about twice as common in men as in women, and much more common in white men than in men of other races. Barrett's esophagus is uncommon in children.
There appears to be an increased risk for Barrett's in people that are overweight or obese. There also appears to be an increased risk for obese people developing esophageal adenocarcinoma, which is the relatively rare, but often deadly, type of esophageal cancer seen in a small number of people with Barrett's esophagus.
As researchers continue to search for causes of Barrett's esophagus, it is important to keep in mind that risk factors are not the same thing as causes. There are people without risk factors who develop Barrett's, and many people with these risk factors will not develop Barrett's esophagus.
