Short answer
BPPV often comes back: studies report recurrence in roughly 10 to 18% of people within a year, and in more over several years1. Risk is higher after head injury, with low vitamin D, osteoporosis or osteopenia, and with some inner ear conditions. In a randomized trial, people with low vitamin D who took vitamin D and calcium had fewer recurrences2. Recognizing the first signs and getting treated quickly keeps each episode short.

What is the link between vitamin D and BPPV?
The crystals in the inner ear are made of calcium carbonate, and vitamin D helps regulate calcium metabolism. Lower vitamin D levels are linked to more BPPV. In a randomized trial of people with recurrent BPPV, those with low vitamin D who took vitamin D and calcium supplements had fewer recurrences than those who did not2. Ask your physician whether checking your level makes sense; we do not prescribe supplements.
Can a head injury or car accident cause BPPV?
Yes. A blow to the head, a fall or the jolt of a collision can shake crystals loose. Post-traumatic BPPV is more likely to affect both ears or more than one canal, so it can take more treatment sessions1. Dizziness after a car accident also needs the neck and a possible concussion checked.
What can lower the chance of BPPV returning?
- Talk with your doctor about vitamin D and bone health if you have had more than one episode
- Stay active, since long periods lying flat are linked to BPPV
- Learn your own early warning signs so you can book quickly
- Use home maneuvers only for the canal and side we have confirmed and taught you
