Weight-Loss Surgery Seems to Beat Diet and Exercise

For people who have a lot of weight to lose, weight-loss surgery appears more effective than diet and exercise, a new review suggests.

The one caveat to this study, however, is that the results only include two years of data, so the long-term outcomes are still unknown. This type of study, called a meta-analysis, attempts to uncover a common thread in a number of previous studies.

"Individuals allocated to bariatric surgery lost more body weight -- on average 26 kilograms [57.3 pounds] -- compared with nonsurgical treatment, and had higher remission rates of type 2 diabetes and metabolic syndrome," said study author Viktoria Gloy, a scientist at the Basel Institute for Clinical Epidemiology and Biostatistics at University Hospital Basel in Switzerland. Metabolic syndrome is a group of symptoms that increase the risk for type 2 diabetes and heart disease.

"After surgery, patients also reported greater improvements in quality-of-life measures, and had greater reduction in medication use than nonsurgical patients," Gloy added.

Gloy and colleagues published the findings online Oct. 22 in the BMJ.  http://www.nlm.nih.gov/medlineplus/news/fullstory_141789.html
