[Statement about the medical and surgical treatment of overweight and obesity].

This is an updated review of the available treatments for obesity, which can be used when lifestyles modifications fail. Using the available information and the experience of the members of this advisory group, a recommendation is given about the most useful treatments, according to the severity of obesity and its complications. With regards to pharmacological treatments, only sibutramine and orlistat are approved on a worldwide basis for the treatment of obesity. These medications achieve a 10% higher weight reduction than lifestyles modification. A third medication, rimonobant, is also more effective than lifestyles modifications, but it was withdrawn due to psychological safety issues. The indications for surgical treatment and a brief description of the available techniques, success rates and complications are outlined. Finally, the need to have followed up protocols for patients and the formation of multidisciplinary treatment teams is underscored.
