Of all the conditions I see in my vertigo clinic, BPPV is the one that causes the most unnecessary fear — and the most unnecessary suffering.
Patients come in after weeks of avoiding certain movements, sleeping upright, refusing to drive, convinced something serious is wrong with their brain. Many have already had a CT scan or MRI that showed nothing. Some have been on antihistamines for months with no improvement.
When I tell them what they actually have — a few displaced calcium crystals in their inner ear — and that I can treat it in the clinic in a single session, the relief on their face is something I never get tired of seeing.
This post is for anyone who has experienced sudden, brief, intense dizziness with head movement. If that description fits you, read on.
What Is BPPV?
Benign Paroxysmal Positional Vertigo — the name tells you everything if you break it down:
- Benign — not dangerous, not life-threatening
- Paroxysmal — comes in sudden, brief attacks
- Positional — triggered by specific head positions or movements
- Vertigo — a false sense of spinning or movement
BPPV occurs when tiny calcium carbonate crystals called otoliths (or "canaliths") — which normally sit in a specific part of the inner ear — break loose and migrate into one of the three semicircular canals. These canals are filled with fluid and are responsible for detecting rotational movement.
When the displaced crystals move inside the canal, they send false movement signals to the brain. The brain receives contradictory information — the eyes say "stationary" but the inner ear says "spinning" — and the result is vertigo.
What Does BPPV Feel Like?
The classic description:
- Sudden, intense spinning sensation lasting 20–60 seconds
- Triggered by specific movements — rolling over in bed, looking up, bending forward, lying down quickly
- Often worst in the morning, first thing after waking
- Accompanied by nausea, sometimes vomiting
- A feeling of being "off" even between the spinning episodes
- No hearing loss, no ear pain, no headache
Key distinction: The vertigo of BPPV is brief and positional. If your dizziness lasts hours, is constant, or occurs without any head movement — that points to a different diagnosis entirely and needs urgent evaluation.
Who Gets BPPV?
BPPV is the most common cause of vertigo worldwide — accounting for approximately 17–20% of all vertigo presentations in specialist clinics. It can affect anyone but is more common in:
- Adults over 40 — the otolith crystals become more fragile with age
- Women — particularly post-menopausal, due to calcium metabolism changes
- People who have had a head injury — even minor trauma can dislodge crystals
- People with prolonged bed rest or immobility
- People with vitamin D deficiency — an increasingly recognised association
- Those with a prior history of inner ear infection (vestibular neuritis)
In many patients — especially older adults — no clear cause is found. This is called idiopathic BPPV and is the most common presentation.
How Is BPPV Diagnosed?
Diagnosis is clinical — meaning it requires a physical examination, not a scan.
The key test is the Dix-Hallpike manoeuvre for the posterior canal (the most commonly affected) and the Roll Test (Supine Roll) for the horizontal canal. These involve moving the patient's head into specific positions while observing the eyes for a characteristic eye movement called nystagmus — an involuntary, rhythmic eye movement that confirms crystal displacement.
At HealthNest Clinic we also use Videonystagmography (VNG) — a specialised test where infrared goggles record eye movements with precision, allowing us to confirm the affected canal and side with certainty before treatment.
Important: BPPV should not be diagnosed by MRI or CT scan alone. These investigations are normal in BPPV because the problem is mechanical, not structural. Many patients arrive having spent ₹8,000–15,000 on brain imaging when a 10-minute clinical examination would have given them the answer.
How Is BPPV Treated?
This is where BPPV becomes genuinely remarkable as a medical condition.
The treatment is a repositioning manoeuvre — performed in the clinic, taking less than 5 minutes, with no medication and no surgery.
For posterior canal BPPV (the most common type), the Epley Manoeuvre is the gold standard. It involves a carefully sequenced series of head and body positions that guide the displaced crystals back to where they belong. Success rate in experienced hands: 80–90% with a single session.
For horizontal canal BPPV, the Barbecue Roll (Lempert) Manoeuvre or the Gufoni Manoeuvre is used depending on the subtype.
After a successful manoeuvre, most patients notice immediate improvement or complete resolution. Some require a second session. A small number have recurrent BPPV — for these patients, we teach a self-repositioning exercise that can be performed at home at the first sign of recurrence.
What does NOT work for BPPV:
- ❌ Antihistamines (betahistine, cinnarizine) — suppress symptoms but do not treat the cause
- ❌ Bed rest — avoiding movement actually prolongs recovery
- ❌ MRI/CT scanning — these are normal in BPPV and do not change management
Experiencing sudden spinning dizziness with head movement? A single vestibular evaluation at HealthNest Clinic can diagnose and treat BPPV on the same visit.

Yes — BPPV has a recurrence rate of approximately 15–30% within one year and up to 50% over five years. This is not a failure of treatment — it is the nature of the condition.
Risk of recurrence is higher in patients with vitamin D deficiency, osteoporosis, and those who have had multiple prior episodes. Supplementing vitamin D to normal levels has been shown in randomised trials to reduce the recurrence rate — we routinely check this in our BPPV patients.
When Is BPPV Not the Diagnosis?
BPPV is common, but not every positional dizziness is BPPV. Features that suggest a different diagnosis and require further evaluation:
- Dizziness lasting hours or days continuously
- Associated hearing loss or tinnitus — may indicate Meniere's disease
- Severe headache with dizziness — needs neurological evaluation
- Dizziness with double vision, difficulty swallowing, or weakness — requires urgent assessment
- Failure to respond to two or three repositioning manoeuvres
- Nystagmus that does not follow the expected pattern on Dix-Hallpike
- Dizziness occurring without any head movement
A thorough vestibular evaluation — including VNG — is essential to confirm BPPV and exclude other causes before committing to repositioning treatment.
A Word From the Clinic
BPPV is one of the most satisfying conditions to treat in ENT and vestibular medicine — because the relief is immediate, the treatment is safe, and patients who were genuinely incapacitated often walk out of the clinic feeling normal for the first time in weeks.
If you have been experiencing brief spinning episodes with head movement — particularly on rolling over in bed — please do not wait. Come in for a vestibular evaluation. In most cases, we can diagnose and treat you in a single visit.
Bottom line: BPPV is caused by displaced inner ear crystals. It is diagnosed clinically with the Dix-Hallpike test and VNG. It is treated with a repositioning manoeuvre in minutes — no medication, no surgery. If your dizziness is brief and triggered by head movement, this is almost certainly what you have. Come in.
