I understand your concern and fear. This diagnosis is a hard one. Bone loss generally first occurs in the spine, followed by loss in the hip so the progression is natural as we age. Some bloodwork should be ordered to determine if there is a cause other than age/genetics. A PTH test will show whether excessive parathyroid hormone is the cause. I would also suggest testing TSH as if you are hyperthyroid, that can cause osteoporosis. The other test you can consider is a calcium urine test to see if you are excreting too much calcium. And lastly, you might want to test your Vitamin D levels to make sure they are optimal (much debate on what optimal is but they should at least be adequate).
You might consider finding an endocrinologist or rheumatologist to work with. Both of these specialties will have knowledge on managing osteoporosis.
