Primary hyperparathyroidism may be cured by removing the adenoma or overactive parathyroid glands.[1][2] In those without symptoms, mildly increased blood calcium levels, normal kidneys, and normal bone density monitoring may be all that is required.[2] The medication cinacalcet may also be used to decrease PTH levels.[2] In those with very high blood calcium levels treatment may include large amounts of intravenous normal saline.[1] Low vitamin D levels should be corrected.[2]
