Vertigo and osteoporosis: The correlation between nutritional intake of Vitamin D and incidence of recurring benign paroxysmal positional vertigo in subjects with hypovitaminosis D
Introduction: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral cause of vertigo. It can be defined as transient vertigo induced by rapid changes in head position associated with a characteristic paroxysmal positional nystagmus. The aim of this study is to evaluate the association between the serum calcium and Vitamin D levels in osteoporotic patients affected by recurrent BPPV. Materials and Methods: Calcium and 25-hydroxy-Vitamin D levels were evaluated in peripheral venous serum samples of 40 BPPV patients. Results: The reduction of serum Vitamin D levels is present in 16 of BPPV patients with recurrence. After nutritional intake of Vitamin D there was a decline of the vertiginous crisis recurrence. Conclusion: Our findings suggested that the administration of Vitamin D dietary supplements can improve, reduce and even eliminate the BPPV vertiginous crisis
