Benign paroxysmal positional vertigo is characterized as brief episodes of vertigo that are exacerbated by the unexpected act of moving to a current provoking location. The study suggests that abnormal vitamin D levels were associated with the incident and relapse of Benign paroxysmal positional vertigo (BPPV).

The objectives were to assess the serum concentrations of vitamin D and calcium (total and ionized) in cases with BPPV, determine if low vitamin D levels were regarded as a cause for BPPV relapse, and determine whether vitamin D supplementation would minimize the risk of BPPV relapse.

Sixty cases with BPPV were included in the study; 53 cases had posterior canal BPPV, while seven had lateral canal BPPV.

- Canalithiasis was the most common type of BPPV pathology. Forty cases had abnormally low levels of vitamin D.

- There was a statistically significant positive correlation between the mean vitamin D assay for all cases with BPPV and serum calcium.

- There was a statistically significant difference in comparing the relapse of BPPV for groups that receive vitamin D after one year of follow-up.

Conclusively, abnormal vitamin D levels were linked with the incident and relapse of BPPV. Correction of low vitamin D levels was linked with the reduction of the relapse of BPPV.
