Two studies report decrease in mortality from bariatric surgery.[1][2] In the Swedish randomized controlled trial, patients with a body mass index of 34 or more for men and 38 or more for women underwent various types of bariatric surgery and were followed for a mean of 11 years. Surgery patients had 5.0% mortality while control patients had 6.3% mortality. This means 75 patients must be treated to avoid one death after 11 years (number needed to treat is 77).[1] In a Utah retrospective cohort study that followed patients for a mean of 7 years after various types of gastric bypass, surgery patients had 0.4% mortality while control patients had 0.6% mortality.[2]
