Osteoporosis is characterized by deterioration in the strength and density of bones, causing them to become fragile. It happens when a person loses too much bone tissue and/or their body isn't able to make enough to maintain bone health. According to the National Osteoporosis Foundation, 54 million Americans have osteoporosis -- or low bone density -- that places them at risk, and about one in two women and one in four men over age 50 will break a bone due to osteoporosis. Given those statistics, knowing about prevention is essential, as is learning about osteoporosis treatment for those who are affected by the disease.
