Osteoporosis is a disease of the bone characterized by a decrease in bone mass and density which causes the bones to become fragile and prone to fracture. According to the World Health Organization the definition of Osteoporosis is a bone mineral density 2.5 standard deviations below the normal young adult mean. The young adult mean is defined as a healthy 30 years old. Those with bone density at 2.5 standard deviations below the mean are at increased risk for fractures, particularly of the hip, spine and wrist. Osteoporosis has recently been acknowledged as one of the most common and serious problems facing postmenopausal women and aging women and men alike.
