Does gastric bypass surgery reduce long-term total mortality compared to a control group?
Gastric bypass surgery is associated with a significant reduction in long-term mortality from major diseases, including heart disease, despite an increase in non-disease related deaths.
Long-term total mortality after gastric bypass surgery was significantly reduced, particularly deaths from diabetes, heart disease, and cancer. However, the rate of death from causes other than disease was higher in the surgery group than in the control group.
Adams et al. (Wed,) studied this question.
