Understanding Proteinuria in the Context of Diabetes

Proteinuria in diabetes is not t a single entity but a progressive spectrum. In thee arlieste stage, called microalbuminuria, the kidneys leak slall contributs of albumin - between 30 and300 mg per day - into thee urine. This stage is often asymptomatic but prepresents a critical window for intervention. Withound thet tremement, microalbuminuria can advance to macroalbuminuria (exceining 300 mg / day), at which point kid ney mone mone and hare.
