Primary Outcome Measures:
- Failure to lose and maintain loss of > or equal to 50% of excess body weight will be considered failure of the bariatric surgery. [ Time Frame: 10 or more years after surgery ]
Secondary Outcome Measures:
- The need for additional surgical or other intervention for treatment of morbid obesity following bariatric surgery will be considered failure of the surgery. [ Time Frame: 10 or more years after surgery ]
The purpose of this study is to obtain long-term follow-up results for bariatric patients who underwent medical management or surgery for treatment of morbid obesity by Ohio State University Medical Center (OSUMC) surgeons during the late 1970s, 1980s, and 1990s. Our hypothesis is that surgical intervention for treatment of morbid obesity leads to sustained weight loss and decreased obesity-related morbidity and mortality.
