Urinary sodium-to-potassium ratio and serum asymmetric dimethylarginine levels in patients with type 2 diabetes.

Obesity modifies the association between sodium and potassium intake and blood pressure. However, the impact of obesity on the relationship between the sodium-potassium balance and cardiovascular risk in type 2 diabetes (T2DM) patients remains unclear. We investigated the relationship between the 24-h urinary sodium-to-potassium ratio and serum asymmetric dimethylarginine (ADMA) level, which is a cardiovascular risk factor, in Japanese T2D patients with or without obesity.
