That may change with BOLD, the Bariatric Outcomes Longitudinal Database, the first repository of patient information and outcomes related to bariatric surgery - procedures that include gastric bypass, in which the bulk of the stomach is tied off and food is rerouted directly to the bottom half of the intestine, and gastric banding, in which the stomach is simply squeezed into a smaller size with a rubber-band-like device. In the first phase of results released by BOLD at the annual meeting of the American Society for Metabolic and Bariatric Surgery (ASMBS), researchers reported safety data indicating that bariatric surgery...
...data support what other studies have been documenting in recent years - that although bariatric surgery, like any surgery, is invasive and risky, it's becoming safer. In 2004, a study in the Journal of the American Medical Association found that the risk of death from gastric bypass was 0.5% (the risk of dying within 90 days after a hip replacement is about 0.3%), and a government analysis revealed that complication rates, particularly infections, from bariatric surgery had declined 21% between...
...several studies have documented the benefits of surgery. In a 2007 trial published in the New England Journal of Medicine, researchers found that obese patients undergoing gastric bypass reduced their risk of death over a period of seven years by 40% and cut their chance of heart disease over the same time period by 56%, compared with people who did not have the surgery. That study was a retrospective analysis of surgery outcomes, however, meaning that doctors could not be sure whether other medical issues may have influenced the study's results...
...Proceedings of the National Academy of Sciences, researchers at Arizona State University's Biodesign Institute, the University of Arizona and the Mayo Clinic in Arizona report a very small study of nine individuals - three of normal weight, three who were morbidly obese and three who underwent gastric-bypass surgery. The team found that each group harbored a different intestinal zoo of microbes and that following their surgery, the gastric-bypass patients' gut bugs ended up looking much more similar to those of the normal-weight patients. (See the Year in Health, from...
...least, not yet. More studies are needed to follow the same people as they lose weight through diet and exercise, to see if the composition of their gut flora changes - as it did with the gastric-bypass patients. What's more, notwithstanding the seeming cause-and-effect link between gut flora and weight, that relationship can be deceiving; a third factor entirely may be causing both - a diet of highly processed foods, for instance, suggests Dr. David Katz, director of the Yale Prevention Research Center. What's more, says Katz, "regardless of the variation of gut flora in the population...
