Chapter 25 OSTEOPOROSIS
Primary osteoporosis results from deterioration of bone mass that is related to aging and decreased gonadal function but is not associated with any chronic illness. Because primary osteoporosis results from decreased gonadal function, early menopause or premenopausal estrogen deficiency may hasten the development of osteoporosis in women. Other risk factors for primary osteoporosis include female gender in general, white or Asian ancestry, sedentary lifestyle, tobacco use, low calcium intake, and low body weight.
