I just had my first bone density screening 2 days ago. It was at a local health fair given by the local hospital and health dept. They used small portable ultrasound machine. One lady tried 5 times to get a reading on my wrist bone and it kept aborting. Another lady tried and got the same, so she then did it on my finger. The reading was T score - 5.5 Z score -5.0 They told me to see my doctor. I did a little research and see this is a bad number, and I'm wondering how bad? I am 56, female, postmenopausal, slim built. I had and was successfully treated for Breast Cancer 5 years ago. My diet has been low in calcium, and up until now I had not been taking calcium supplements, although I have been taking One a Day for women 50+ for the last 2 years ( contains some calcium). I am also taking triamterene/HCTZ for blood pressure control. Non smoker. I exercise at least 30 minutes 3 to 5 days a week, and am an avid power walker.View Thread
