Managing severe obesity: understanding and improving treatment adherence in bariatric surgery.

Severe obesity (body mass index ≥40 kg/m) is a chronic disease that is associated with significantly increased risk of serious and chronic health problems as well as impaired quality of life. For those with severe obesity, bariatric surgery is the most effective treatment for significant and long-term weight loss and resolution of comorbid medical conditions, particularly diabetes. Long-term success is thought to depend to some degree on the patient's ability to adhere to a complex set of behaviors, including regular attendance at follow up appointments and following stringent dietary, exercise, and vitamin recommendations. Here, we summarize the current research on behavioral adherence in patients with severe obesity presenting for bariatric surgery and we highlight challenges and make recommendations for improved self-management before and after surgery.
