DIABETIC NEPHROPATHY – MAGNITUDE OF THE PROBLEM Most important cause of morbidity and mortality in Type 1 diabetes – progression is faster 50% with clinical nephropathy reach ESRD by 10 years 75% with clinical nephropathy reach ESRD by 20 years In Type 2 diabetes mellitus progression is slower – 20% reach ESRD About 25 – 50% of all cases of ESRD is due to diabetes ? Racial factors ? Indians / Blacks more susceptible High economic burden on society
