<unk>  is a disorder in which the parathyroid glands do not produce enough parathyroid hormone (PTH). This kind of hormone plays an important role in regulating and maintaining a balance of calcium and phosphorus. Studies demonstrate that conditions such as damage to the parathyroid glands after a neck or head surgery, radiation therapy for tumor on the face or neck, low levels of magnesium and family histories may be associated with the cause of<unk> . The low production of parathyroid hormone in<unk>  may lead to symptoms such as paresthesias, muscle aches or cramps, twitching or spasms, even seizure, anxiety or nervousness and headaches. Tests on levels of blood calcium, blood magnesium, blood phosphorus and parathyroid hormone can help diagnose<unk> . Treatments for<unk>  include taking  calcium carbonate and vitamin D supplements to normalize blood levels of calcium and phosphorus.
