What do you suggest if my wife has normal calcium(9.4) but high pth?

Secondary hyperpara: Hi. Normal serum and ionized calcium in the setting of elevated PTH is called secondary hyperparathyroidism (2-HPT). 2-HPT is NOT a disease of the parathyroids, but is a response of the parathyroids to the threat of low blood calcium. The most common cause is low vitamin D, but other causes such as intestinal malabsorption or a primary renal calcium leak may also cause 2-HPT. See endocrinologist.
