Evolving directions in obesity management.

Over the past decade, treatment for obesity has been limited because of an incomplete understanding of the pathophysiology of obesity, lack of recognition of it as a disease, and limited efficacy of treatment options. Safety concerns related to medical and surgical approaches for obesity have also been a major barrier. The challenging nature of obesity management is reflected in a survey of primary care physicians which indicated that treating patients with obesity can be as difficult as treating patients with nicotine or alcohol dependence.
