Bariatric surgery reduces long-term all-cause mortality and the incidence of type 2 diabetes in obese adults.
Bariatric surgery offers a significant long-term survival advantage for severely obese individuals, reducing the risk of death by nearly 30% over 16 years compared to non-surgical care. This benefit extends to a drastic reduction in the development of type 2 diabetes.
GoodSupportsHIGH confidence
At 16 years’ follow-up, surgery was associated with a 29% lower risk of death from any cause (0.71, 0.54 to 0.92; P=0.01) compared with usual care.
Why this rating
Based on large prospective observational studies (SOS, Utah) with long follow-up.
