Usually in the work often encounter patients ask a question that is, long bone spurs to supplement calcium, my point of view is this, calcium in the human body is divided into blood calcium and bone calcium, the two transformed into each other to maintain a dynamic balance, due to a variety of reasons lead to the loss of calcium is first manifested as a decrease in blood calcium, the body in order to maintain life, so we must be from the bone in the intake of calcium to ensure that the blood calcium level of stability, so that after a period of time, there is a lack of calcium in the bone, which is the osteoporosis. After a period of time, there is a lack of calcium in the bone, which is called osteoporosis. After osteoporosis, if the body has calcium intake again, the calcium in the blood will be deposited to the bone, not evenly deposited to the surface of the bone, but first deposited to the joints where the force is more concentrated and the activity is more, so that osteophytes are formed in the joints or in the stress areas, that is, the bone spurs that we say. Therefore, patients with osteophytes should supplement calcium to avoid the occurrence of the process of “calcium into the blood —- bone redeposition”, which can prevent the occurrence of osteophytes.
