How long does it take to progress from Stage 3 CKD to Stage 4 CKD?

The length of time it takes to progress from Stage 3 chronic kidney disease (CKD) to Stage 4 CKD depends on various factors, including age, gender and ethnicity – and especially the cause (diagnosis) of CKD.

However one study found that the average length of time a person spends in Stages 3A and 3B CKD is 12.7 years (Ku E, Johansen KL, McCulloch CE. Time-centered approach to understanding risk factors for the progression of ckd. Clin J Am Soc Nephrol. 2018; 13(5): 693-701).

Note. Not all people progress (worsen) from CKD3 to CKD4. Some stabilise, a few get better completely.
