Deficiency of which of the following mineral(s) can lead to hypocalcemia by impairing the ability of the parathyroid gland to secrete parathyroid hormone? 1. Phosphate 2. Magnesium 3. Sodium 4. Potassium Select the correct answer using the code given below:
2 only
Severe hypomagnesemia impairs PTH secretion from the parathyroid gland (and causes end-organ PTH resistance), leading to functional hypoparathyroidism and hypocalcemia. Phosphate, sodium, and potassium deficiencies do not act through this PTH-secretion mechanism.
