Renal pathophysiology · Physiology

Secondary hyperparathyroidism in CKD is mainly due to:

  1. Increased renal vitamin D synthesis
  2. Persistent hypercalcemia
  3. Phosphate retention and low calcium
  4. Elevated calcitonin secretion from the thyroid
Show answer and explanation

Correct answer: Phosphate retention and low calcium

Phosphate retention and reduced vitamin D activation lower serum calcium. This stimulates parathyroid hormone secretion.
