When the absorption of calcium is less than the excretion of calcium, it is a negative calcium balance.
People enter the old age, due to the loss of tissue and organ function in the body, and the acceleration of bone calcium loss, absorption of calcium can not compensate calcium excretion, the body is easily in a negative calcium balance. At this time, in order to ensure the normal function of physiological functions, it is necessary to use calcium in the bone bank to maintain the balance of ionized calcium in the body.
Although the daily use of bone calcium is insignificant, but slowly and continuously use of bone calcium will eventually cause bone calcium deficiency, osteoporosis, fractures and other pathological changes.
