Primary Hyperparathyroidism, often caused by a parathyroid gland having an adenoma on it, increases the release of the parathyroid hormone (PTH) in the body. This causes the excess release of calcium from bones into the blood, and the weakening of said bones. A low Vitamin D level often accompanies hyperparathyroidism (or perhaps is a result of?) and while most calcium is excreted then through urine, some of it forms into kidney stones.
Recently, some studies show, and consequently some doctors now recommend, a course of vitamin-D to re-absorb the calcium that had been released.
Given a patient with low vitamin D, a calcium level of 2.9 mmol/L and PTH level of 12.9 mg/dl, what would be the expected impact of a course of Vitamin D at 50,000 IU/week ?
Would the effects of hyperparathyroidism be fully mitigated while on the course, or if not, to what degree would they be?
