Vitamin D and BPPV

Vitamin D and BPPV -

Yang, B., Lu, Y., Xing, D. et al. Association between serum vitamin D levels and benign paroxysmal positional vertigo: a systematic review and meta-analysis of observational studies. Eur Arch Otorhinolaryngol 277, 169–177 (2020).
  • Benign paroxysmal positional vertigo (BPPV) is one of the most common neuro-otological disorders seen in clinical practice.
  • Prior cohort and case series studies have highlight a potential relationship between BPPV and vitamin D status.
  • The current systematic review and meta-analysis examines over 18 studies to analyze if there is a relationship between BPPV, recurrent BPPV, and vitamin D status.
  • The meta-analysis suggests that the serum level of vitamin D is lower in patients with BPPV, especially recurrent BPPV, than in controls.
  • In addition, vitamin D deficiency (< 20 ng/dl) appears to be an independent risk factor for BPPV. As such, clinicians should be cognizant of patients’ vitamin D status in the prevention of recurrent BPPV.
