Estimation of Some Mineral (Calcium, Phosphorous, Vitamin 25(OH) D, And Alkaline Phosphatase) in Osteoporosis Patients In Kirkuk City

Abstract

usually develops because of insufficient sources of endogenous and exogenous vitamin D (inadequate intake or excessive consumption) and may eventually result in bone mass reduction, especially in elderly woman [8]. Aging is associated with decreased; sun exposure, oral intake and skin activation of vitamin D, and vitamin absorption. All of these factors may contribute to vitamin D insufficiency, which is required for calcium absorption and bone mineralization. The low serum vitamin D is associated with increased PTH secretion which in turn leads to bone resorption and increased renal calcium excretion [9]. Vitamin D is essential for calcium metabolism as well as for fracture prevention and a recent review suggested that the optimal serum 25 (OH) D lies in the region of 50-80 nmoL-1
