Bariatric Surgery Best for Long-Term Weight Loss

05/09/2016

Bariatric Surgery Best for Long-Term Weight LossThe benefits of weight loss surgery for obese and overweight individuals have been known for a long time. However, a new study now shows that the results of bariatric surgery are not just short-term, and much of the weight appears to stay off for at least 10 years.

In fact, the study goes on to state that bariatric surgery is more effective than other surgical procedures and non-surgical techniques when it comes to weight loss and long-term weight management.

Published in the journal JAMA Surgery, the findings are notable because they include the results of a decade-long follow-up, in addition to two separate areas of study.

Lead author of the study Matt Maciejewski, who is a professor of medicine at Duke University School of Medicine, in Durham, N.C., said: “This study suggests that patients interested in bariatric surgery, especially gastric bypass surgery, should be able to lose a significant amount of weight and keep that weight off for a very long time."

For the study, the researchers first compared thousands of veterans who had received bariatric surgery to another group that hadn't. After a year, the bariatric surgery group had lost 31% of their starting weight, while the other group had lost just 1%.

After 10 years, the bariatric surgery group had managed to maintain a nearly 21% greater weight loss than their non-surgical counterparts, highlighting the long-term benefits that weight loss surgery can have.

The researchers then looked into how effective different types of weight loss surgery are. They found that after four years, patients who had undergone a gastric bypass had lost nearly 28% of their starting weight, while those who a had sleeve gastrectomy lost about 18% and those with gastric banding lost about 11%.
