IFSO Position Statement on Bariatric Surgery in Class I Obesity

I am glad to send you the link to the “IFSO Position Statement on Bariatric Surgery in Class I Obesity (BMI 30-35)” published on the April issue of our official journal Obesity Surgery.

The Position Statement has been written by a working group formed by Luca Busetto, Maurizio De Luca, John Dixon, Walter Pories, Scott Shikora and myself and it has been discussed and approved by the Executive Board of IFSO.

After a careful review of available data about safety and efficacy of bariatric surgery in patients with class I obesity, this panel reached a consensus on ten clinical recommendations.

Class I obesity conveys an increased risk of co-morbidities, impairs physical and mental health-related quality of life, and it is associated to an increased psychosocial burden, particularly in women. The need for effective and safe therapies for class I obesity is great and not yet met by nonsurgical approaches. Eligibility to bariatric surgery has been largely based on body mass index (BMI) cut points and limited to patients with more severe obesity levels. However, obese patients belonging to the same BMI class may have very different levels of health, risk, and impact of obesity on quality of life. Individual patients in class I obesity may have a co-morbidity burden similar to, or greater than, patients with more severe obesity. Therefore, the denial of bariatric surgery to a patient with class I obesity suffering from a significant obesity-related health burden and not achieving weight control with nonsurgical therapy simply on the basis of the BMI level does not appear to be clinically justified. A clinical decision should be based on a more comprehensive evaluation of the patient’s current global health and on a more reliable prediction of future morbidity and mortality.

I am glad to share with you this important step in the development of Bariatric Surgery and I hope this document will be useful for your clinical reality to be able to accept such patients and finally open the way to bariatric and metabolic surgery in Class I obesity.
