A few words of thanks would be greatly appreciated.

Calcium deficiency - Definition


A calcium deficiency is the lack or absence of calcium in the body. Calcium has, among other functions, that of assuring good bone and dental health. It is also involved in muscle contraction. The most common cause is a vitamin D deficiency that affects calcium metabolism. A calcium deficiency appears through muscle cramps, tremors, or in cases of severe deficiency, an increased risk of cardiac arrhythmias. In the long term, it leads to bone problems (osteoporosis), especially among the elderly and women. A diet rich in dairy products is recommended if a calcium deficiency is found, as well as supplements if a vitamin D deficiency is responsible.
