5 Stages of CKD: An Overview
A dignosis of Chronic Kidney Disease (CKD) means that kidney failure is NOT immediate; instead, it is a gradual progression. The five stages of this progression are as follows:
- Stage One: Your kidneys are beginning to lose function but are still filtering at approximately 90% capacity
- Stage Two: Kidney filtration function falls to between 60-89% and you may start requiring medications and/or diet and exercise modifications
- Stage Three: At the beginning of stage three (3A), your kidneys are functioning at 45-60% — by the end of stage three, they are functioning between 30-45%
- 3A: More regular testing may be required and secondary conditions (such as hypertension) may need more monitoring and care
- 3B: More serious/noticeable symptoms may appear and medication regimen is likely to increase
- Stage Four: Kidney function is between 15-30% and referral to transplantation services or dialysis is likely
- Stage Five: End-Stage Renal Disease (ESRD) — kidney filtration is under 15% and serious medical intervention (i.e., dialysis or transplant) is required for survival
