Vertigo is defined as the subjective perception of rotation or translation without external movement. The subtype benign paroxysmal positional vertigo (BPPV) is the commonest one. Although BPPV has been named benign, some patients suffered recurrences. Vitamin D regulates serum calcium and phosphorus homeostasis and maintaining bone structure. goal of this study To measure the serum levels of 25-hydroxyvitamin D3 (25-OH D3) and calcium total & ionized in patients with BPPV and determine whether there is a difference in the serum levels of vitamin D3 between patients with and without recurrence, Thirty patients with BPPV were divided into 2 groups: non-recurrence (Group I) and recurrence (Group II). Detailed history and clinical examination were performed, and blood samples were collected, and the serum level of 25-OH D3 and calcium total & ionized was assessed and compared in both groups,  There was non-significant difference between both groups regarding the affected canal and laterality between both groups. Serum vitamin D, total and ionized calcium levels were lower in recurrence group than non-recurrence group, with non-significant difference between both groups.
