Diagnose diabetic nephropathy

Diabetic glomerular sclerosis in diabetes-induced kidney damage, mainly in clinical edema, proteinuria, hypertension, and this case, patients timely treatment, it is likely to be diabetic nephropathy . So, how do we diagnose diabetic nephropathy?
1, the diagnosis of diabetic nephropathy depends on kidney damage: the early renal damage mainly to the increase in glomerular filtration rate and microalbuminuria, the last several years. Further, there may be asymptomatic proteinuria began to intermittently later, compared with last. Persistent proteinuria prompted the breadth and severity of renal disease. Severe glomerulosclerosis with massive proteinuria and hypoproteinemia, nephrotic syndrome, often accompanied by hypertension and creatinine clearance rate of decline. More than 90% of patients with diabetic retinopathy.
2, the diagnosis of diabetic nephropathy depends on renal manifestations: a typical case how polyuria, polydipsia, polyphagia, weight loss of "a little" symptoms. The light may be asymptomatic. The disease develops slowly, the progression of the disease involving other organs, such as atherosclerosis, coronary heart disease, retinopathy, cataracts, peripheral neuropathy, etc. in addition to involving the renal acceptable.
