What is hypoparathyroidism? What's the treatment to this? How is it connected to hypokalemic periodic paralysis and renal disease? Please answer.

Low parathyroid horm. Parathyroid glands make a hormone that regulates calcium in the blood. Damage from thyroid surgery or autoimmune disease are main causes. Severe muscle spasm is the chief symptom. High doses of calcium & vit D+ magnesium, is the treatment. No hormone replacement is yet available. Not connected to periodic paralysis. Rx. can cause kidney stones and could lead to renal failure, not common.
