Aspiration Therapy for Obesity.

Aspiration therapy is a weight loss therapy in the United States for patients with a body mass index between 35 kg/m2 and 55 kg/m2. Aspiration therapy allows patients to remove up to one-third of calories consumed at a meal and causes patients to eat fewer calories than prior to starting treatment. Studies demonstrate 14.2% to 21.5% total body weight loss in participants who complete 1 year of treatment and maintenance of weight loss in patients treated for 2 years. Aspiration therapy is a safe and effective new treatment of obesity.
