The parathyroid glands regulate calcium in your body by making more or less of a hormone called parathyroid hormone (PTH). The parathyroid glands constantly measure calcium levels in your blood. If the calcium level gets too high, the normal glands sense this and stop production of PTH.This lowers the calcium in your body and returns your calcium levels to normal. Abnormal glands cannot regulate calcium balance.he parathyroid glands constantly measure calcium levels in your blood.
