    ### Instruction:
    What to do for Primary Hyperparathyroidism ?
    ### Response:
    - Primary hyperparathyroidism is a disorder of the parathyroid glands, in which one or more of the parathyroid glands are overactive. As a result, the gland releases too much parathyroid hormone (PTH).  - High PTH levels trigger the bones to release increased calcium into the blood, causing blood calcium levels to rise above normal.
