Short answer
Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo. Tiny calcium carbonate crystals (otoconia) come loose from the utricle and drift into one of the semicircular canals. When you lie down, roll over or look up, they move and trigger brief, intense spinning, usually lasting under a minute. A canalith repositioning maneuver moves them back out, often within one to three visits1.

Why does the room spin when I roll over in bed?
Rolling over moves the loose crystals through the canal, and the spinning starts a few seconds later, peaks and fades within about a minute2. Other common triggers are lying back, getting up in the morning, looking up at a high shelf and bending down. Nausea and a lingering off-balance feeling between spells are common. Constant spinning that does not change with position, or vertigo with neurological symptoms, is not typical BPPV and needs prompt medical evaluation.
Why do inner ear crystals come loose?
Often there is no clear reason, but BPPV becomes more common with age and is linked to head injury, inner ear conditions such as vestibular neuritis or Ménière's disease, long periods lying flat, migraine and low vitamin D1. Because it can come back, we also teach you the early signs to watch for.
How is BPPV diagnosed and treated?
We perform the Dix-Hallpike and supine roll tests while recording your eyes with infrared video goggles. The direction of the nystagmus shows which ear and which canal is affected, and whether the crystals are floating or stuck to the cupula. Then we choose the matching maneuver: Epley or Semont for the posterior canal, BBQ roll or Gufoni for the horizontal canal, or a deep head-hanging maneuver for the anterior canal. A Cochrane review confirms the Epley maneuver is a safe, effective treatment for posterior canal BPPV3.
How soon can I get BPPV treatment in Alpharetta or Cumming?
Urgent appointments are available within 48 hours at our Cumming and Alpharetta clinics, and treatment usually starts at the first visit. Patients come from Johns Creek, Milton, Roswell, Suwanee and Sugar Hill. The BPPV guideline advises against routine anti-vertigo medicines, because repositioning treats the cause1.
