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.
In the United States, 10 million people have osteoporosis (80% of those are women), and 34 million are at risk for developing the disease due to low bone density. Osteoporosis is a public health issue because the disease contributes to 1.5 million fractures (broken bones), including 350,000 hip fractures annually. Osteoporosis is a disorder of the bones in which the bones become brittle, weak, and easily damaged or broken. 2  Bone mass (bone density) reaches its peak around age 25, and decreases after age 35 years and decreases more rapidly in women after menopause.
