Blood calcium above the normal range - in CKD usually from over-suppressed PTH, excess calcium binders, or tertiary hyperparathyroidism.
In advanced CKD and dialysis, hypercalcemia typically reflects disordered mineral metabolism: over-treatment with calcium-based binders and active vitamin D, low bone turnover (adynamic bone disease), or tertiary hyperparathyroidism. Persistent hypercalcemia contributes to vascular calcification, calciphylaxis risk, and suppresses PTH further. Management: reduce calcium load (switch to non-calcium binders), adjust vitamin D and calcimimetics, and correct underlying PTH status. The calcium-phosphorus product is tracked together because both drive calcification.
Overactive parathyroid glands caused by kidney failure — driven by low vitamin D, high phosphate, and low calcium — damaging bones and vessels if untreated.
Bone disease caused by chronic kidney disease — abnormal bone turnover from calcium, phosphate, vitamin D, and PTH disturbances.
A progressive condition characterized by gradual loss of kidney function over months or years, classified into 5 stages based on eGFR.
