Treatment depends on the type of<unk>  encountered. Primary People with primary<unk>  who are symptomatic benefit from parathyroidectomy—surgery to remove the parathyroid tumor (parathyroid adenoma). Indications for surgery are: * Symptomatic<unk>  * Asymptomatic<unk>  with any of the following: * 24-hour urinary calcium > 400 mg (see footnote, below) * serum calcium > 1 mg/dl above upper limit of normal * Creatinine clearance > 30% below normal for patient's age * Bone density > 2.5 standard deviations below peak (i.e., T-score of -2.5) * People age < 50 Surgery can rarely result in hypoparathyroidism. Secondary In people with secondary<unk> , the high PTH levels are an appropriate response to low calcium and treatment must be directed at the underlying cause of this (usually vitamin D deficiency or chronic kidney failure). If this is successful, PTH levels return to normal levels, unless PTH secretion has become autonomous (tertiary<unk> . Calcimimetics A calcimimetic (such as cinacalcet) is a potential therapy for some people with severe hypercalcemia and primary<unk>  who are unable to undergo parathyroidectomy, and for secondary<unk>  on dialysis. Treatment of secondary<unk>  with a calcimimetic in those on dialysis for CKD does not alter the risk of early death; however, it does decrease the likelihood of needing a parathyroidectomy. Treatment carries the risk of low blood calcium levels and vomiting.
