text_1: 60-year-old man.  Low calcium on screening labs.  History of thyroidectomy for hyperthyroidism.  I followed up the low calcium with parathyroid hormone, phosphorus, and vitamin D levels which confirmed hypoparathyroidism.  Patient was totally asymptomatic.  Why do I need to treat?  Can it be left alone until he develops symptomatic hypocalcemia?
