The diagnosis of diabetic nephropathy includes proteinuria and the presence of diabetic fundopathy in combination.
Diabetic nephropathy should be suspected when persistent microalbuminuria occurs 5 years after the onset of type 1 diabetes and at the time of diagnosis of type 2 diabetes. Diabetic nephropathy should be considered if the duration of the disease is longer, with gradual clinical proteinuria, or even large amounts of proteinuria or nephrotic syndrome, and in combination with other complications of diabetes, such as diabetic fundopathy.
If the following conditions occur: no diabetic retinopathy; acute kidney injury; significant increase in proteinuria in a short period of time; no hypertension; glomerulonephritic hematuria; diabetes mellitus should be considered in combination with other chronic kidney diseases, and renal biopsy is recommended to confirm the diagnosis.
Diabetic nephropathy should go to the hospital in time and be treated under the guidance of specialized physicians.
