Osteoporosis

Osteoporosis, which means "porous bones," is a condition of excessive skeletal fragility resulting in weakened bones that break easily. A combination of genetic, dietary, hormonal, age-related, and lifestyle factors all contribute to this condition. Osteoporosis usually progresses painlessly until a fracture occurs, which is usually in the hip, spine, or wrist.

Overall, approximately eight million American women and 2 million men have osteoporosis. Women are four times more likely than men to develop osteoporosis because of the loss of estrogen at menopause. (Estrogen blocks or slows down bone loss.) Over half of all women over the age of 65 have osteoporosis. Even though osteoporosis is often thought of as a disease that only affects older people, it can strike at any age.

Osteoporosis leads to 1.5 million fractures, or breaks, per year, mostly in the hip, spine and wrist, and costs $14 billion annually. One in two women over the age of 50 will suffer an osteoporosis-related fracture.
