回复：中年女性进入更年期的症状:

Ming Gu,

have been reading your blog and articles, learned a lot from you. Thanks.

got a quick question:

is it possible for a woman to have NORMAL bone density , yet have ABNORMAL Vitamin D level? got a friend, who has all the osteoporosis symptoms, (pre-menopausal), had undergone bone density test, it was -1.1, the doctor she is fine,  but the doctor refused to order vitamin D level. The doctor said if your bone density is normal, logically your D level is normal, thus there is no need to do Vitamin D check. she is not taking calcium. Her last year physical shows normal calcium level.

is it true?
