Life Expectancy after Bariatric Surgery – The Swedish Obese Subjects Study with Dr. Clifford J. Rosen

Published

Obesity is a major cause of morbidity in the United States and many other high-income countries. Its association with diabetes, hypertension, cardiovascular disease, and ultimately reduced life expectancy is well known. A healthy diet and regular exercise can prevent obesity as well as help achieve weight loss in obese individuals. However, for some individuals with severe obesity, these lifestyle changes alone are not enough. Bariatric surgery can be key in helping such patients lose weight and maintain weight loss, thereby reducing their risk of harmful obesity associated outcomes.

In this episode of Curbside Consults, I am joined by Dr. Clifford J. Rosen −− Associate Editor at the New England Journal of Medicine (NEJM) and Endocrinologist and Professor of Medicine at Tufts University School of Medicine −− to discuss a recent study published in NEJM entitled “Life Expectancy after Bariatric Surgery in the Swedish Obese Subjects Study.”
