Chronic kidney disease

eGFR< 15, Stage V;

eGFR< 30, Stage IV;

eGFR< 60, Stage III.

There are an array of pathological change causing CKD related outcome that need to be followed up by nephrologist: chronic anemia, secondary hyperparathyroidism, hyperphosphatemia, mineral bone disease, hypocalcemia, hypertension, hyperlipidemia, cardiovascular risk, proteinuria, and etc, to name a few.

If eGFR is lower than 60 ml/min/1.73m2, or persistent proteinuria without clear etiology, or uncontrolled hypertension with multiple anti-hypertensives (very early or very late onset hypertension: < 15 yo or > 50 yo), you will need to see a nephrologist, who usually takes care of Nephrology and Hypertension.
