Weight loss surgery effective, but risk remains

Bariatric surgery is effective at helping patients lose weight and improve obesity-related conditions such as diabetes, high blood pressure and sleep apnea, according to a review of published studies. Complications are possible following these procedures, but death rates generally are low, according to School of Medicine researchers who performed the analysis.

Weight-loss surgery provides benefit to high-risk, severely obese patients

Among surgeries for obesity, a newer, increasingly popular procedure called sleeve gastrectomy provides more weight loss to high-risk severely obese patients than adjustable gastric banding, a new study by Esteban Varela, MD, suggests. Two years after surgery, patients in both groups had lost substantial weight, but those who had had a sleeve gastrectomy shed an average of 16 additional pounds.

Weight-loss surgery cost-effective for all obese

Bariatric surgery is not only cost-effective for treating people who are severely obese, but also for those who are mildly obese, according to a new study from Washington University School of Medicine in St. Louis. The findings support making bariatric surgery available to all obese people, the researchers say.
