Will lack of calcium stunt growth?
When such a deficiency does develop, parathyroid hormone acts to transfer calcium from the bones in order to maintain the mineral’s all-important presence in the bloodstream. This of course strips your bones of their calcium and in turn weakens your bones, making them more brittle and subject to breaking. The result of a mild insufficiency of calcium over the long term may be thinning bones, termed osteoporosis or the softening of bony tissue, called osteomalacia. The faulty metabolism of calcium during childhood may result in a condition called rickets. Recent research even points to calcium deficiency as being a possible cause of hypertension (high blood pressure) and of colon cancer. Severe calcium deficiency, which is defined as a reduction of calcium levels in the bloodstream below a certain normal range, has its own clinical manifestations. The main syndrome is tetany, which involves sensations of numbness and tingling around the mouth and fingertips and painful aches and spasms
