Overview
Common causes of hypocalcemia include [cause1], [cause2], and [cause3].
Causes
Common Causes
Hypocalcemia can be the consequence of multiple disease processes, some of which will be mentioned in the following discussion. The most common cause is the inability to mobilize calcium from bone which is primarily induced by decreased levels of the parathyroid hormone (PTH) due to derangement of the parathyroid gland function (ie, the gland responsible of calcium homeostasis) or vitamin D deficiency.
- Hypoparathyroidism: It signifies diminished activity of the parathyroid gland due to multiple reasons: autoimmune destruction (included in the polyglandular autoimmune syndrome type I), resection of the glands as a possible complication of total thyroidectomy or genetic diseases affecting the gland's function. A second entity that should be mentioned is pseudohypoparathyroidism which is characterized by normal gland function but inability of the PTH-target organs (bone and kidney) to respond to PTH. Patients present with hypocalcemia but high PTH levels.
