Surgery for severe obesity saves lives




An extensive swedish study from the Sahlgrenska Academy has established that surgery reduces premature death in patients with severe obesity. A long-term follow up has shown that mortality is significantly lower among patients who undergo surgery than among those who do not.

The results are published recently in The New England Journal (NEJM).

We show for the first time that surgery against obesity not only leads to long-term loss of weight, it also significantly reduces mortality", says Lars Sjstrm, professor emeritus at the Sahlgrenska Academy, located in Gteborg in Sweden.

Over 4,000 severely obese patients were included in the study, which Lars Sjstrm started as long ago as 1987. Half of these patients underwent stomach surgery (bariatric surgery) intended to give weight loss. The remaining patients received advice concerning lifestyle changes, also intended to give weight loss. Some of these patients also received medicines for weight loss, but even so, the conventional therapy was considerably less effective than the surgical procedure.

The group receiving conventional therapy had even increased somewhat in weight after 10 years, while patients who had undergone surgery decreased in weight by 16%, on average. Bariatric surgery is the only therapy for severe obesity for which there is scientific evidence that it reduces mortality", says Lena Carlsson, professor at the Sahlgrenska Academy.

A long-term follow up for between 5 and 18 years of the patients who had undergone surgery showed that mortality among these patients was 29% lower than it was among the other patients.

The mechanisms behind the lower mortality are not clear. It seems that the reduction in risk depends less upon the actual loss of weight itself than on the fact that the patients have undergone surgery against obesity. This observation opens new possibilities for discovering previously unknown mechanisms behind the increase in risk linked to obesity, and thus opens the possibility of developing new therapys", says Lars Sjstrm.

The scientists also considered the effects of a number of biochemical and other variables in the analysis, including smoking, stress and prior medical history.
