Klinefelter syndrome is associated with a significantly increased risk of metabolic syndrome, type 2 diabetes, and abdominal adiposity, independent of some socioeconomic factors.

Men with Klinefelter syndrome have a much higher risk of metabolic syndrome and diabetes than the general population. Regular screening for blood sugar, lipids, and waist circumference is essential, even if weight appears normal, due to the tendency for abdominal fat accumulation.

Almost half of the KS patients fulfilled criteria for the metabolic syndrome, whereas it was true for only 10% of the control group... Type 2 diabetes is frequent in hypogonadal patients... hypogonadism is also more prevalent among type 2 diabetics
