Bariatric surgery significantly reduces all-cause mortality and mortality from specific chronic diseases (diabetes, CAD, cancer) compared to non-surgical management.
Bariatric surgery not only helps you lose weight but significantly extends your life expectancy by reducing the risk of death from heart disease, diabetes, and cancer. This mortality benefit is unique to surgical weight loss and is not seen with lifestyle-induced weight loss.
StrongSupportsHIGH confidence
Unlike weight loss secondary to intensive lifestyle intervention, weight loss secondary to bariatric surgery has been shown to be associated with decreased mortality.
Why this rating
Based on the Swedish Obesity Subjects (SOS) study, a large prospective case-controlled study.
