Role of Vitamin D Supplementation in Prevention of Recurrent Benign Paroxysmal Positional Vertigo

Abstract

Objective: to determine of vitamin D administration in preventing recurring benign paroxysmal positional vertigo events. Study Design: Quasi experimental study. Place and Duration of Study: Department of ENT, Combined Military Hospital, Rawalpindi Pakistan, from Jul 2021 to Jan 2022. Methodology: Study was conducted on 80 patients who were diagnosed with recurrent benign paroxysmal vertigo. Patients were enrolled in two groups (Group A and B) by lottery method. Vitamin D supplements and canal repositioning manoeuvre were administered to patients in Group A, while just canal repositioning procedure was given to patients in Group B. Patients were told to follow up over six months. Vitamin D supplement consumption and BPPV attacks were tracked over 6-month follow up period. Results: In follow-up period, most patients in Group A 24(60.0%) had no episodes of vertigo, whereas 10(25.0%) had single episode of vertigo. Furthermore, none of the patients experienced three episodes. Many patients in Group B 19(47.5%) developed one or more episodes. The difference between both groups was statistically significant (p<0.05). Conclusion: Low vitamin D levels are found in most individuals with benign paroxysmal positional vertigo events. Vitamin D supplementation significantly decreased the frequency and recurrence of benign paroxysmal positional vertigo events, according to the findings.
