The loss of bone occurs silently and progressively. Often there are no symptoms until the first fracture occurs. As we age some of our bone cells begin to dissolve bone matrix (resorption), while new bone cells deposit osteoid (formation). This process is known as remodeling. For people with osteoporosis, bone loss outpaces the growth of new bone. Bones become porous, brittle and prone to fracture. Around the world, 1 in 3 women and 1 in 5 men are at risk of an osteoporotic fracture. In fact, an osteoporotic fracture is estimated to occur every 3 seconds.
