    The AspireAssist® is a new, FDA-approved weight loss solution for people with obesity. Unlike many other weight loss procedures, it’s non-surgical and reversible. Placing the device is an outpatient procedure. Patients can often return home within one to two hours, and be back at work quickly. The AspireAssist works by reducing the calories absorbed by the body, while helping you make gradual, healthy changes to your lifestyle.
