Bariatric Surgery Associated with 3-Year Increase in Life Expectancy for Obese Patients – Endocrinology Network



An analysis of data from an ongoing study in Switzerland is shedding light on the impact bariatric surgery can have on life expectancy compared to standard obesity care.

While neither group of patients achieved the life expectancy of the general population, results of the study suggest patients undergoing bariatric surgery lived a median of 3 years longer than their counterparts in the study’s control group.

“Our study shows that bariatric surgery prolongs (life expectancy) by three years. But even after surgery, patients still have a shorter life expectancy than the general population. That’s why it’s very important for bariatric patients to be offered adequate postoperative monitoring and follow-up,” noted Lena Carlsson Ekander, MD, PhD, Professor of Clinical Metabolic Research at Sahlgrenska Academy, in a statement.

To learn more about the effects of treatment course on mortality in obese patients, Carlsson Ekander and a group of colleagues designed an analysis of the ongoing Swedish Obese Subjects (SOS) study. The SOS study, which recruited participants from September 1, 1987 through January 31, 2001, provided investigators with information related to 4047 obese patients and 1135 patients from the general population, which were used as a reference cohort.

Of the 4047, 2007 underwent surgery and 2040 were used as a control group. When the investigators performed their analysis on December 31, 2018, the median duration of follow-up was 24 (IQR, 22-27) years for patients in the surgery group, 22 (IQR, 21-27) years for patients in the control group, and 20 (IQR, 19-21) for patients
