Renal complications of type 2 diabetes
Raised blood glucose levels and related microvascular disease are associated with progressive damage to the kidneys. This damage becomes detectable when protein (primarily albumin) is excreted in the urine in higher concentrations than normal. As the severity of the damage increases, the quantity of protein in the urine also increases. When the level of albumin in the urine is fairly low, the condition is known as microalbuminuria or incipient nephropathy; higher albumin excretion is described as proteinuria. Eventually the condition can lead to renal failure.2
Epidemiological studies report prevalence rates of microalbuminuria in patients with type 2 diabetes ranging from 8% to 32% with most estimates being around 25%.415 Prevalence
