More Weight Loss from Bariatric Surgery than Standard Care in Severe Obesity

A recent review of clinical data on bariatric surgery compared to standard care has revealed higher average difference in body mass index (BMI) levels for bariatric surgery, reflecting more weight loss in patients with severe obesity.  The review, published in the August 2011 issue of Obesity Reviews (see abstract), was performed by researchers at the University of Alberta (Edmonton, Canada) examining clinical literature through February 2009 on 2,619 patients with a mean body mass index (BMI) between 42 to 58 kg/m².

Severe obesity is associated with increased risk of mortality, with the risk being higher for women than men having a BMI of 35 kg/m2 or greater.  This is illustrated in a separate study in the International Journal of Obesity. See below:
