They are used to prevent or treat several conditions that may cause hypocalcemia (not enough calcium in the blood). The body needs calcium to make strong bones. Calcium is also needed for the heart, muscles, and nervous system to work properly. The bones serve as a storage site for the body's calcium. They are continuously giving up calcium to the bloodstream and then replacing it as the body's need for calcium changes from day to day. When there is not enough calcium in the blood to be used by the heart and other organs, your body will take the needed calcium from the bones. When you eat foods rich in calcium, the calcium will be restored to the bones and the balance between your blood and bones will be maintained. Pregnant women, nursing mothers, children, and adolescents may need more calcium than they normally get from eating calcium-rich foods. Adult women may take calcium supplements to help prevent a bone disease called osteoporosis. Osteoporosis, which causes thin, porous, easily broken bones, may occur in women after menopause, but may sometimes occur in elderly men also. Osteoporosis in women past menopause is thought to be caused by a reduced amount of ovarian estrogen (a female hormone). However, a diet low in calcium for many years, especially in the younger adult years, may add to the risk of developing it. Other bone diseases in children and adults are also treated with calcium supplements. Calcium supplements may also be used for other conditions as determined by your health care professional. Injectable calcium is administered only by or under the supervision of your health care professional. Other forms of calcium are available without a prescription.
