Hypoparathyroidism is a common cause of<unk> . Calcium is tightly regulated by the parathyroid hormone (PTH). In response to low calcium levels, PTH levels rise, and conversely if there are high calcium levels then PTH secretion declines. However, in the setting of absent, decreased, or ineffective PTH hormone, the body loses this regulatory function, and<unk>  ensues. Hypoparathyroidism is commonly due to surgical destruction of the parathyroid glands. Hypoparathyroidism may also be due to autoimmune problem. Some causes of<unk>  are as follows:
Hypocalcemia
Hypernatremia
Hyponatremia
Hypouricemia
Hypophosphatemia
Hypercalcaemia
Hyperaemia
Hyperammonemia
