Bariatric surgery significantly reduces all-cause mortality, cardiovascular mortality, and major adverse cardiovascular events (MACE) compared to medical therapy in patients with severe obesity and Type 2 Diabetes.

For severe obesity and Type 2 Diabetes, bariatric surgery is the most effective treatment for reducing heart disease risk and death. It significantly lowers the risk of heart attack, stroke, and heart failure compared to medical therapy alone. Discuss surgical options with a specialist if lifestyle changes and medications are insufficient.

GoodSupportsHIGH confidence
Bariatric surgery has been shown to be associated with reduction in all-cause mortality (HR 0.55), CV mortality (HR 0.59), incidence of heart failure (HR 0.5), myocardial infarction (HR 0.58) and stroke (HR 0.64, p <0.001 vs control for all interactions)... The results from the two most recent large observational studies... demonstrated significant probability of reduction in major adverse cardiovascular events (MACE)
