CKD basics
CKD has been a worldwide worrisome health problem in recent years. CKD is defined as either kidney damages or decreased GFR of less than 60 mL/min/1.73 m2 over 3 month (The Kidney Disease Outcomes Quality Initiative (K/DOQI) of the National Kidney Foundation).
CKD can be categorized to 5 stages, ranging from nearly normal kidney function to renal failure, which denotes the total or near-total loss of your kidney function and requires dialysis or kidney transplant.
According to the definition from the Renal Association, CKD can be divided into 5 stages:
Stage 1: normal or increased GFR﹥90 mL/min/1.73 m2 with protein in the urine
Stage 2: mild reduced kidney function (GFR: 60-83 mL/min/1.73 m2)
Stage 3: moderate reduction of kidney function (GFR: 30-59 mL/min/1.73 m2)
Stage 4: severely reduced kidney function (GFR: 15-29 mL/min/1.73 m2)
Stage 5: end-stage renal failure (GFR < 15 mL/min/1.73 m2 or on dialysis)
* All GFR values are normalized to an average surface area (size) of 1.73m2.
Stage 1: normal or increased GFR﹥90 mL/min/1.73 m2 with protein in the urine
