Popularly known as “crystal dizziness,” benign paroxysmal positional vertigo (BPPV) is one of the most frequent diagnoses in ENT practices. Its most common symptom is vertigo — short, sudden spinning episodes triggered by head movements such as bending over, lying down, or getting up.
BPPV is one of the leading causes of dizziness and, fortunately, one of the simplest to diagnose and treat. Still, many people deal with symptoms for long periods, mostly because they postpone seeking medical care.

What is BPPV?
Benign paroxysmal positional vertigo occurs when tiny crystals inside the inner ear (known as otoconia) detach from their original location and become loose — which is why the condition is commonly called “crystal dizziness.”
These crystals are responsible for detecting linear movements of the head and telling the brain when we’re moving up, down, forward, or backward, even when the body is still — like inside a car or an elevator.
When these crystals are loose, the information sent to the brain becomes incorrect, triggering rotational vertigo — the sensation that the body or surroundings are spinning. Symptoms usually worsen during certain head movements and improve within seconds.
Which doctor should you see?
If you suspect BPPV, you should see an otolaryngologist or an ENT specialized in dizziness and tinnitus.
During the consultation, the doctor will listen to your complaint — usually described as “intense dizziness when getting in or out of bed, changing positions on the pillow, or bending over” — and perform specific tests to confirm BPPV.
If the doctor consulted is not qualified to perform treatment, they will refer you to someone who is.
How is BPPV treated?
BPPV treatment is performed in the clinic, usually immediately after diagnosis.
The doctor will position the patient in different ways to identify the affected ear. These diagnostic tests are known as Dix-Hallpike and Head Roll Test.
Once the affected side is identified, a canalith repositioning maneuver is performed — a guided sequence of head movements that directs the crystals back to their correct location.
Even though it may seem simple, this procedure must only be performed by a qualified doctor. Trying to treat the condition at home without proper guidance is usually ineffective and can worsen symptoms.
BPPV treatment is fast and highly effective — almost all patients fully recover after just one maneuver. So don’t hesitate to see a doctor.
FAQ: frequently asked questions about BPPV
To wrap up, here are some frequently asked questions about BPPV. Check them out!
1. Can BPPV go away on its own?
In some patients, symptoms may resolve spontaneously. However, in most cases, the repositioning maneuver performed in the doctor’s office is necessary for immediate improvement.
2. Can BPPV come back?
Yes. About 35% of patients may experience recurrence from time to time. In any case, the repositioning maneuver remains a simple and effective solution.
3. Why do these crystals become loose?
In some cases, BPPV is triggered by specific events such as head trauma, accidents, or intense rides at amusement parks. However, in most situations, no triggering factor is identified — the crystals simply detach spontaneously.
4. Is BPPV common in older adults?
Yes. Although BPPV can occur at any age, it is particularly common in seniors and may even lead to falls and household accidents due to aging of the structures involved.
5. Are there medications for BPPV?
No medication can treat BPPV — meaning no drug can make the crystals return to their original location. If symptoms don’t improve on their own, the only effective treatment is the repositioning maneuver. Some medications, however, may help relieve discomfort temporarily.
6. What if dizziness doesn’t improve after the maneuver?
A small percentage of patients may require a second maneuver. If symptoms still persist, the doctor must investigate other possible causes triggering the dizziness.
If you suffer from frequent episodes of dizziness, do not delay consulting a specialist. In this case, you should see an otolaryngologist or an otoneurologist — the ENT doctor specializing in dizziness and tinnitus.
