According to the National Institutes of Health (NIH), about 34 million Americans have osteoporosis. Another 18 million have low bone mass and are at an increased risk for the disease. Osteoporosis is common among the elderly, but the disease can strike at any age. Although it is more common in older women, men can also develop osteoporosis. One of every 2 women and 1 in every 4 men older than 50 years of age will have an osteoporosis-related fracture in their lifetime.
Osteoporosis causes bones to become weak and brittle â so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine. Bone is living tissue that is constantly being broken down and replaced. Osteoporosis occurs when the creation of new bone doesn't keep up with the removal of old bone. Osteoporosis affects men and women of all races. But white and Asian women â especially older women who are past menopause â are at highest risk.
