BPPV vertigo is treatable with specific head movements that reposition tiny crystals inside your inner ear, and most people feel relief after just one or two sessions. About 72% of people recover immediately after a single repositioning maneuver, and 92% are symptom-free within a week. The key is identifying which ear is affected and performing the correct sequence of movements.
What Causes BPPV
Your inner ear contains small calcium crystals that help you sense gravity and motion. In BPPV, some of these crystals break loose and drift into the semicircular canals, the fluid-filled tubes your brain relies on to detect head rotation. When you change positions, the loose crystals shift and send false signals to your brain, creating the sensation that the room is spinning. This is why the vertigo hits with specific movements: rolling over in bed, tilting your head back, or bending forward.
The crystals can break free from aging, a head injury, or an inner ear infection. In many cases, there’s no identifiable cause at all. The posterior canal (the one closest to the back of your head) is affected in the vast majority of cases, which is why most treatment maneuvers target that canal specifically.
How to Tell Which Ear Is Affected
Before you can treat BPPV, you need to know which ear the crystals are in. The simplest way is to notice which direction triggers your vertigo. If rolling to your right side in bed sets it off, your right ear is likely the problem. If lying back and turning your head to the left causes spinning, it’s probably the left ear.
Doctors confirm this with the Dix-Hallpike test: you sit on an exam table, turn your head 45 degrees to one side, then lie back quickly so your head hangs slightly over the edge. If BPPV is present in that ear, you’ll experience a burst of vertigo after a brief delay of 2 to 5 seconds, with your eyes making a characteristic rotating and upward-beating movement. The spinning typically lasts less than a minute and becomes weaker if you repeat the test. This short duration and the brief delay before it starts are what distinguish BPPV from more serious causes of vertigo.
The Epley Maneuver
The Epley maneuver (also called the canalith repositioning procedure) is the most widely used treatment. It works by guiding the loose crystals out of the semicircular canal and back into the part of the inner ear where they belong. The procedure involves four head positions, each held for about 30 seconds after symptoms stop.
Here’s the sequence, using the right ear as an example:
- Position 1: Sit on the edge of a bed. Turn your head 45 degrees to the right, then lie back quickly so your head hangs slightly over the edge of the bed. Wait 30 seconds after any dizziness passes.
- Position 2: Without lifting your head, turn it 90 degrees to the left (so you’re now looking 45 degrees to the left). Hold for 30 seconds after dizziness stops.
- Position 3: Roll your body onto your left side, turning your head another 90 degrees so you’re looking down at the floor. Hold again for 30 seconds.
- Position 4: Slowly sit back up with your head tilted slightly down. Stay seated for about 15 minutes.
If your left ear is the problem, reverse the directions: start by turning your head to the left, then rotate toward the right. A doctor or physical therapist can perform this with you the first time, but it’s safe to do at home once you know which ear is affected. The maneuver may need to be repeated three or more times in a single session for full effect.
The Half Somersault Maneuver
If the Epley feels awkward to do alone, the half somersault maneuver is an alternative designed specifically for home use. Developed by Carol Foster, MD, at the University of Colorado School of Medicine, it doesn’t require you to lie on a bed or hang your head over an edge.
For the right ear: kneel on the floor and tilt your head back to look at the ceiling briefly. Then tuck your chin and place the top of your head on the floor, as if you’re about to do a somersault. Turn your head to face your right elbow. Raise your head quickly so it’s level with your back (still on all fours). Finally, sit up fully with your head upright. Wait 15 seconds between each position for any dizziness to settle.
This maneuver works on the same principle as the Epley, using gravity to guide crystals out of the canal. Some people find it easier to remember and more comfortable to repeat at home.
The Semont Maneuver
The Semont maneuver is a third option with a cure rate comparable to the Epley, around 90% within the first week. It involves sitting upright, then quickly lying on your affected side with your head turned 45 degrees away from the ground. After holding that position, you swing rapidly to the opposite side without pausing in the middle, keeping the same head angle. The fast movement helps fling the crystals out of the canal.
A randomized trial comparing the two found no significant difference in cure rates (92.5% for the Epley versus 90% for the Semont), though people who received the Epley reported less residual dizziness immediately after treatment. The Semont is sometimes recommended for people who can’t extend their neck backward, and it’s straightforward enough to do at home without assistance.
What to Do After Treatment
Older guidelines advised patients to sleep sitting up, wear a neck collar, and avoid lying on the affected side for up to five days after a repositioning maneuver. These restrictions were based on the worry that crystals might drift back into the canal. Research has since shown they’re unnecessary. Six out of seven controlled studies found that postural restrictions have no significant effect on either treatment success or recurrence rates. People who went about their normal activities after the maneuver recovered just as well as those who followed strict positioning rules.
That said, some practitioners still suggest avoiding rapid head movements for the first 48 hours. This is more about comfort than necessity, since the inner ear can feel slightly off-balance as it readjusts.
If It Comes Back
BPPV recurs in roughly 10% to 18% of people within the first year after successful treatment. When it does return, the same repositioning maneuvers work again. Frequent recurrence, however, may point to an underlying issue worth addressing.
Vitamin D plays a meaningful role. People with recurring BPPV have significantly lower vitamin D levels than those who don’t relapse, and a meta-analysis found that vitamin D supplementation cut recurrence rates by more than half compared to no supplementation. The connection likely comes down to calcium metabolism: vitamin D helps regulate the calcium crystals in your inner ear, and a deficiency may make them more prone to breaking loose. If your BPPV keeps coming back, getting your vitamin D level checked is a reasonable step.
Signs It May Not Be BPPV
BPPV has a recognizable pattern: brief episodes of spinning triggered by head movement, lasting under a minute, with no hearing loss or other neurological symptoms. Certain features suggest something more serious. Vertigo that lasts for hours, changes direction when you shift your gaze, or comes with numbness, weakness, double vision, slurred speech, or difficulty walking could indicate a problem in the brain rather than the inner ear. Purely vertical eye movements during a dizzy spell (eyes bouncing straight up and down) also point to a central cause rather than BPPV. Any of these warrant prompt medical evaluation.
