It is characterized by proteinuria, decline in glomerular filtration, hypertension, and high risk of cardiovascular morbidity and mortality. Deterioration of renal function in diabetic nephropathy develops through five clinical stages characterized by the respective histologic description. Genetic susceptibility, hyperglycemia, high blood pressure and duration of diabetes mellitus definitely play a role in the pathogenetic sequence. Early diagnosis, appropriate patient follow up and treatment are essential to improve the outcomes. Interdisciplinary approach and close collaboration of nephrologists and diabetologists are essential for timely detection of disease progression. Tight glycemic control under the supervision of diabetologists, screening of patients, and once a year report of albuminuria and glomerular filtration allow for detection of renal damage in the early stages and timely referral to a nephrologist. The points of interest given in this overview are description of clinical staging in relation to pathologic classification, repetition of basic causal features, and brief analysis of treatment.
