Question: What causes high calcium in the body? My parathyroid test is good.
Dr. Hibberd's Answer:
A high level of calcium in the blood is called hypercalcemia. Overactivity of the parathyroid gland is the most likely cause. Since your parathyroid test is normal, I would advise you to consult your primary care physician as early as possible since there could be other likely causes of hypercalcemia that are best ruled out or treated promptly.
Other causes could be the presence of certain types of cancers (lung/breast/multiple myeloma) or inflammatory lung diseases (tuberculosis/sarcoidosis). In addition, sometimes dehydration, high intake of calcium, or side effects of certain medications can also raise blood calcium levels.
