The Impact of Severe Vitamin D Deficiency and Its Correction on Bone Mineral Density (BMD) in Postmenopausal Women (Vitamin D)
It is well known that postmenopausal women are at risk for osteoporosis. The study hypothesis is that vitamin D deficiency (≤17.5nmol/L) is frequently associated with osteomalacia and will cause low BMD estimation in DXA scan due to insufficient bone mineralization.
We assume that among these postmenopausal women, Vitamin D treatment will improve bone mineralization and will cause a rapid increase in BMD. According to the results, bisphosphonates therapy may be an unnecessary treatment.
The objective of this study is to evaluate the impact of severe vitamin D deficiency and its correction on Bone Mineral Density (BMD) in postmenopausal women.
