For many years it has been standard practice for doctors to recommend bone density evaluation (with “DEXA” scans, or dual-energy X-ray absorptiometry, a special type of X-ray) around menopause because estrogen is a potent bone-builder, and estrogen begins to wane at menopause, or even before menopause.According to the National Osteoporosis Foundation, 30 million American women (and 14 million American men) have osteoporosis today. This is a preventable disease, and if not prevented can seriously compromise quality of life, and, ultimately, longevity also.The DEXA scans measure bone density at several sites and give a standardized “score” to the bone density (called the T-score). A T-score of zero (0) is perfect.Anything below zero represents bone loss.A T-score of minus 1.5 (-1.5) means osteopenia (bone loss) and a T-score...
