In many cases, people do not develop symptoms of osteoporosis in the early stage, giving it the name the Silent Disease. Often, the first indication of the disease is discomfort, especially in the back. Other times the first signs of osteoporosis are compression fractures or collapsed vertebra that can happen without an injury. Pain may come on suddenly or intensify slowly over time. These fractures also result in a loss of height – in some people as much as six inches – and the curved spine and stooped posture known as dowager’s hump (kyphosis).
