Large, intentional weight loss induced by bariatric surgery significantly reduces the 2-year incidence of hypertension, diabetes, hyperinsulinemia, and lipid disturbances in severely obese individuals compared to matched controls.
For severely obese individuals, bariatric surgery is a highly effective intervention for preventing the onset of type 2 diabetes, hypertension, and lipid disorders over a 2-year period. The key is achieving large, sustained weight loss, which surgery facilitates more reliably than conventional treatments.
Intentional weight loss in the obese causes a marked reduction in the 2-year incidence of hypertension, diabetes and some lipid disturbances.
Why this rating
Large prospective controlled intervention study (SOS) with matched controls, though non-randomized.
