Have you gone through menopause? For women, this is the big determining factor with bone health.
If you have not, there is no formal diagnosis. That doesn't mean you don't have low bone density, just no diagnosis is given premenopausal women. Also you can expect what bone you do have now to decrease as you go through menopause and your body stops producing estrogen.
I'm assuming your T-score is a -2.8 and not a 2.8? Also, what bone(s) have you broken? Severe osteoporosis is not used in clinical diagnoses anymore, but at one time was determined by a score of -2.5 or lower
combined with the presence of a non traumatic fracture. So, if you're postmenopausal and have not fractured a bone, you have osteoporosis.
There are a lot of reasons why this could be happening.
1. You might not have ever built up your peak bone mass and when you went/go through menopause, it decreases rapidly
2. It could be genetic
3. You could have a calcium absorption problem
4. You could be Vitamin D deficient
5. You could have a problem with your parathyroid
That's a start. I'd make an appt with an endocrinologist to have some tests run to see if it's a hormonal problem.
I'd also go to the National Osteoporosis Foundation website (
www.nof.org ) and get their booklet "Boning Up on Osteoporosis" for a ton of good information. We use it in our osteo rehab classes as a teaching tool.
If you do have osteoporosis and you are through menopause, I'd suggest two things. One, you ask for a referral for Physical Therapy for postural exercises and ADL's (Activities of Daily Living). Then, I'd talk to the doctor about medications. At your age and this stage of bone loss, you'll need an RX to get you back on track. Nothing natural will do it and you're way too young to suffer a life changing fracture.
