Clinical Features of Benign Paroxysmal Positional Vertigo: Sufficiency of Serum Vitamin D Levels

The risk factors for recurrent benign paroxysmal positional vertigo (BPPV) include female gender and underlying hypertension, diabetes mellitus, dyslipidemia, osteoporosis, and vitamin D deficiency. In this study, we investigated serum-active vitamin D levels in patients with recurrent BPPV. We statistically examined the age, sex, BPPV attack frequency, and serum 25-hydroxyvitamin D (serum 25(OH)D) levels in 60 patients (17 males and 43 females) with recurrent BPPV between October 2015 and February 2023. All the subjects had been diagnosed as having definite BPPV (based on diagnostic criteria).
