Calcium is important for healthy bones and teeth, as well as for normal muscle and nerve function. Normal blood calcium levels are maintained through the actions of parathyroid hormone (PTH), kidneys and intestines. Hypocalcaemia is an electrolyte imbalance and is indicated by a low level of calcium in the blood. Hypercalcemia is a condition associated with high calcium.
Causes include Vitamin D abnormalities, PTH (parathyroid hormone) level disorders, kidney failure, Magnesium deficiency, Alcoholism, Certain types of medications may also cause calcium imbalance. There are genetic conditions that can lead to this disorder as well.
Treatment involves identification of underlying cause for calcium imbalance and tackling the problem accordingly.
