Common complications in CKD include secondary hyperparathyroidism, characterized by high-turnover renal osteodystrophy, with increased bone turnover leading to bone fragility and an increased risk of fractures, involving disturbances in calcium, phosphorus, PTH, vitamin D, and FGF23 levels (Brandenburg and Ketteler, 2022). Here, FGF23 is linked to secondary hyperparathyroidism.
