Abstract
Introduction: Vestibular migraine (VM) is considered to be the second most common cause of vertigo and most common cause of spontaneous episodic vertigo. Keeping in mind the global health burden of low vitamin D level and its effect on pain and balance. Objective: This study aiming at determining the effect of vitamin D on VM. Methods: A prospective, cross-sectional study conducted in Basrah hearing and balance center with 37 patients diagnosed with VM. Female to male ratio were 4.3:1. Mean age of 37.622 +/- 14.36 years. Results: It was found a significant relation between the frequency of VM attacks and the level of vitamin D as patients with low or sub optimal level have more frequent attacks than those with normal vitamin D level (p-value = 0.0012). Conclusion: These findings suggest that assessment of vitamin D level may be important in patients suffering from vestibular migraine. Vitamin D supplementation may serve as a simple and cost-effective adjunct in the management of these patients.
