Insufficient vitamin D intake secondary to using unfortified foods and social customs (such as avoiding sun exposure), however, contribute to the development of disease. Poor diet, a lack of sun exposure, and the age related decline in the dermal synthesis of 7-dehydrocholesterol are among the factors that predispose to vitamin D deficiency and consequent bone disease. Here, we present a case of severe osteomalacia presenting with multiple vertebral fractures due to poor diet and a lack of exposure to sunlight.eninfo:eu-repo/semantics/closedAccessOsteomalaciaVitamin D deficiencyVertebral fracturesOsteoporosisReview Article361303610.1007/s12020-009-9209-8Q4WOS:0002677810000072-s2.0-7034958009419543841Q2
