Body Mass Index (BMI) is a metric commonly used to assess body composition, inform clinical diagnoses, and predict risk for developing various chronic illnesses. In bariatric surgery, a patient’s BMI is relied upon to determine surgical eligibility, and reductions in BMI are commonly reported as a postoperative outcome. Using three clinically significant classifications of obesity, we sought to investigate whether preoperative differences in BMI influence weight loss, biochemical risk factors, and metabolic characteristics following bariatric surgery.
