Registration Number
NCT02776982
Lead Sponsor
Mayo Clinic
Brief Summary

This study is being done to help understand why some people with an increased amount of central obesity, without gastroesophageal reflux, develop changes to the lining of their esophagus that can potentially lead to esophageal adenocarcinoma (cancer).
