What happens if high calcium goes untreated?

If left untreated, hypercalcemia can lead to serious complications. For example, if the bones continue to release calcium into the blood, osteoporosis, a bone-thinning disease, can result. If urine contains too much calcium, crystals may form in the kidneys. Over time, these crystals may combine to form kidney stones.

Can hypercalcemia be cured?

Treatment is aimed at the cause of hypercalcemia whenever possible. People with primary hyperparathyroidism (PHPT) may need surgery to remove the abnormal parathyroid gland. This will cure the hypercalcemia. People with mild hypercalcemia may be able to monitor the condition closely over time without treatment.
