Surgery for severe obesity saves lives
August 24, 2007An 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 today in The New England Journal of Medicine.
"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 Sjöström, professor emeritus at the Sahlgrenska Academy, located in Göteborg in Sweden.
Over 4,000 severely obese patients were included in the study, which Lars Sjöström 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 changes in lifestyle, also intended to give weight loss. Some of these patients also received medicines for weight loss, but even so, the conventional treatment was considerably less effective than the surgical procedure.
"The group receiving conventional treatment 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 treatment 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 associated with obesity, and thus opens the possibility of developing new treatments", says Lars Sjöström.
The researchers also considered the effects of many biochemical and other variables in the analysis, including smoking, stress and previous medical history.

Fat Politics: The Real Story behind America's Obesity Epidemic by J. Eric Oliver (Author) It seems almost daily we read newspaper articles and watch news reports exposing the growing epidemic of obesity in America. Our government tells us we are experiencing a major health crisis, with sixty percent of Americans classified as overweight, and one in four as obese. But how valid are these claims? In Fat Politics, J. Eric Oliver shows how a handful of doctors, government bureaucrats, and health researchers, with financial backing from the drug and weight-loss industries, have campaigned to create standards that mislead the public. They mislabel more than sixty million Americans as "overweight," inflate the health risks of being fat, and promote the idea that obesity is a killer disease. In reviewing the scientific evidence, Oliver shows there is little proof that obesity... |

The Obesity Epidemic: Science, Morality and Ideology by Michael Gard (Author) The Obesity Epidemic adds a much-needed voice of skepticism to the increasingly alarmist debate about weight and health. Gard and Wright show that "obesity" is above all a deeply problematic cultural and political concept, making clear that the social meaning of fat is determined largely by moral and ideological agendas -- agendas that are all the more powerful because they cloak themselves in the mantle of objective science and public health. Indeed, this book demonstrates how and why concepts such as "science" and "health" are themselves far more problematic than those who invoke them like to admit. THE OBESITY EPIDEMIC is a superb contribution to the sociology of knowledge, and an essential text for anyone who wants to understand the current moral panic over fat. |

The Evolution of Obesity by Michael L. Power (Author), Jay Schulkin (Author) In this sweeping exploration of the relatively recent obesity epidemic, Michael L. Power and Jay Schulkin probe evolutionary biology, history, physiology, and medical science to uncover the causes of our growing girth. The unexpected answer? Our own evolutionary success. For most of the past few million years, our evolutionary ancestors' survival depended on being able to consume as much as possible when food was available and to store the excess energy for periods when it was scarce. In the developed world today, high-calorie foods are readily obtainable, yet the propensity to store fat is part of our species' heritage, leaving an increasing number of the world's people vulnerable to obesity. In an environment of abundant food, we are anatomically, physiologically,... |

Cognitive-Behavioral Treatment of Obesity: A Clinician's Guide by Zafra Cooper DPhil DipPsych (Author), Dr. Christopher G. Fairburn DM FMedSci FRCPsych (Author), Deborah M. Hawker PhD DClinPsy (Author) The first cognitive-behavioral treatment manual for obesity, this volume presents an innovative therapeutic model currently being evaluated in controlled research at Oxford University. From leading clinical researchers, the approach is specifically designed to overcome a major weakness of existing therapies: posttreatment weight regain. The book details powerful ways to help patients not only to achieve weight loss, but also to modify the problematic cognitions that undermine long-term weight control. Drawing on strategies proven effective with such problems as binge eating, the manual contains everything needed to implement the treatment: intervention guidelines, case examples, and reproducible handouts and forms. |
