Bariatric surgery significantly reduces the incidence of new-onset type 2 diabetes, hypertension, and dyslipidemia in severely obese individuals compared to no intervention.
For severely obese individuals, bariatric surgery is a highly effective preventive measure against developing type 2 diabetes, high blood pressure, and high cholesterol. The study shows that surgery reduces the risk of developing these conditions by 55-94% compared to no treatment. This should be a key factor in treatment decisions for severe obesity, especially in regions with high metabolic disease rates.
The relative risk reductions associated with bariatric surgery were 94, 93, and 55% for the development of T2DM, HTN, and dyslipidemia, respectively.
