Although easy to treat with precisely defined head position maneuvers (, i.e. Epley maneuver for posterior canal BPPV), its occurrence let alone recurrence can be alarming for patients. Although viral infections as well as head trauma are known risk factors for BPPV, these afflictions are not something a patient has any voluntary control over. However, vitamin D deficiency has also emerged as another potential risk factor for BPPV and IS something that a patient may have some control over.
Only in the past few years, increasing number of research has been published showing that:
• Osteoporosis is associated with increased risk of BPPV. [link]
• There appears to be an association between BPPV and decreased serum vitamin D. [link]
• During months when Vitamin D levels are historically low (May), BPPV occurs/recurs more frequently whereas during months where Vitamin D levels are historically high (Sept), BPPV occurs/recurs less frequently. [link]
• Improvement of serum 25-hydroxyvitamin D3 levels with vitamin D supplementation is associated with substantial decrease in BPPV recurrences. [link]
The theory that explains Vitamin D's relationship to BPPV goes something like this... The matrix found within bone and otoconia are similar. Calcium is the main component of otoconia and Vitamin D is required for calcium regulation. Therefore, a correlation between Vitamin D and BPPV is theoretically possible by its effect on calcium.
SO... at least for an individual who has suffered from BPPV with osteoporosis and certainly for those who suffer from BPPV recurrences, it may be worthwhile to take Vitamin D supplementation especially if serum levels are low.
