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 two million men have osteoporosis. Women are four times more likely than men to develop osteoporosis because of the loss of estrogen at menopause. (Estrogen slows down bone loss.) Over half of all women over the age of 65 have causes of osteoporosis.
