The Effect of Obesity Medications on the Healthcare System

Patrick O’Neil, PhD, has been working in the delivery and development of obesity treatments since the 1970’s, and in that time he’s seen the approach to this chronic, pervasive condition go from that of a neglected, scorned behavioral difficulty to a major global health problem and the subject of accelerating medical research. It’s not been a smooth or easy course, and he will highlight some of the many stumbles along the way, especially the checkered history of weight loss drugs.

But now that effective obesity medications are here, with many more prospects on the horizon, what are the impacts on the healthcare system? How effective are these drugs, and who should use them? What are the side effects? How affordable are they? Can the healthcare system handle the potential demand for treatments possibly needed by a third or more of the population? And are drugs alone enough?
