What body mass index (BMI or weight(kg)/height [m2]) definition of obesity serves as the standard indication for bariatric surgery when medical therapy has failed and com or bid conditions exist?
A. Overweight (BMI 25.0-29.9)A 1991 NIH Consensus Conference recommended that bariatric surgery was indicated for a body mass index (BMI) of 35.0-39.9 when medical therapy has failed and comorbid conditions exist. When no comorbid conditions exist, a BMI of 40 or greater is required. This standard continues to be used by insurers, although recent studies have shown benefit in lower BMI groups.
