The peak incidence of diabetic nephropathy is typically found in individuals who have had diabetes for 10-20 years; after 20 years, the rate steadily declines. Individuals who have no proteinuria after 20-25 years have a risk of developing overt renal disease of only about 1% per year.
Among patients with T1DM, diabetic nephropathy rarely develops before 10 years' duration of the disease.
Among newly diagnosed patients with T2DM, only approximately 3% have overt nephropathy.
