Osteoporosis occurs when the body fails to form enough new bone or when too much old bones are reabsorbed by the body or both. In normal healthy bone, remodeling occurs when osteoclasts eaten away at the bone tissues and osteoblasts come in and refill the holes with new bone. As part of this process, the body uses calcium and phosphate to produce strong bone during youth. If calcium intake is not sufficient or the body did not absorb enough calcium from diet, bone production and bone tissues may suffer. The bone becomes less dense and more susceptible to breakage. In fact, in people with osteoporosis, bone fractures often occur with very little stress. Osteoporosis occurs gradually during aging and it is more prevalent in women.
