Quick Answer
Vertigo from BPPV is a sudden spinning sensation, often with unsteadiness or vomiting, caused when tiny ear crystals called otoconia break loose and drift into a semicircular canal, so certain head positions trigger spinning. Each bout typically lasts less than a minute. A canalith repositioning procedure, a series of guided head movements, resolves most cases in one or two visits.
What the research says
Repositioning maneuvers work better than sham or no treatment. In a Cochrane review of 11 randomized trials with 745 adults, the Epley maneuver led to complete resolution of vertigo far more often than a sham maneuver or control (odds ratio 4.42; 95% CI 2.62 to 7.44; five studies, 273 participants), raising the share of patients who recovered from 21% to 56%. About 36% of patients had a recurrence after treatment (Hilton and Pinder, Cochrane Database of Systematic Reviews, 2014).
Vestibular suppressant drugs did not show a clear benefit. In a meta-analysis of 5 randomized trials with 296 patients, antihistamines, phenothiazines, anticholinergics, and benzodiazepines may have no effect on symptom resolution at the longest follow-up of 14 to 31 days (standardized mean difference -0.03; 95% CI -0.53 to 0.47), while the comparison favored repositioning maneuvers over the drugs (relative risk 0.63; 95% CI 0.52 to 0.78) (Sharif et al., Academic Emergency Medicine, 2023).
Severe dizziness can happen during the procedure itself. In a meta-analysis of 5 nonrandomized studies covering 1,177 cases, a "postural crisis" (severe dizziness with a sudden fall backward or sideways when sitting up at the end of the procedure) occurred in 10% of cases (95% CI 6% to 15%), and the authors advise preparing in advance for this fall risk (Kim et al., Medicine, 2025).

What is vertigo, exactly?
Vertigo is the sudden feeling of spinning or moving. You may feel like you are spinning, or it may seem like the room around you is spinning. It is a sensation, not a disease, and it has several possible causes.
The most common cause is a condition called benign paroxysmal positional vertigo, or BPPV. Despite the long name, the condition is common and usually not serious. It causes brief periods of dizziness that range from mild to intense. Certain changes in head position set the spells off most often: tipping the head up or down, lying down, or turning over or sitting up in bed [1].
BPPV rarely signals a serious illness. But the dizziness can make you unsteady, which raises your chance of falling. The good news is that a healthcare professional can usually treat BPPV during an office visit [1].
What are the symptoms of vertigo?
The symptoms of BPPV center on short bursts of dizziness tied to head position. Between spells, you may feel completely normal. The main symptoms include:
Dizziness.
A sense of spinning or moving, or a feeling that the area around you is spinning or moving. This is the vertigo itself.
A loss of balance or unsteadiness.
Stomach upset and vomiting.
Symptoms come and go. Each bout most often lasts less than a minute. Spells can disappear for a while and then return [1].
The head movement that triggers an episode varies from person to person. But a change in head position almost always brings on the symptoms. Some people also feel off balance when standing or walking.
Atypical rhythmic eye movements, called nystagmus, most often accompany the symptoms of BPPV. This involuntary eye movement is a key clue your healthcare professional looks for during an exam.
Symptom | What you may notice |
Spinning sensation | Feeling like you or the room is turning |
Trigger pattern | Spells start after a change in head position |
Duration | Each bout usually lasts under a minute |
Unsteadiness | Feeling off balance when standing or walking |
Stomach symptoms | Nausea, upset stomach, or vomiting |
Eye movements | Rhythmic eye movements (nystagmus) during spells |
When should vertigo be treated as an emergency?
It is not common for BPPV to signal a serious illness. Still, get medical care right away if dizziness or vertigo comes with any of the following [1]:
Red flag | Why it matters |
A new, different, or severe headache | May point to a problem beyond the inner ear |
Fever | Suggests infection rather than BPPV |
Double vision or trouble seeing | Can signal a nervous-system issue |
Hearing loss | Points to a different ear condition |
Trouble talking | A possible stroke warning sign |
Weakness in an arm or leg | A possible stroke warning sign |
Passing out | Needs immediate evaluation |
Falling or trouble walking | Raises injury risk and may signal another cause |
Numbness or tingling | Can indicate a nervous-system problem |
You should also see your healthcare professional if your dizziness or vertigo is sudden, intense, long-lasting, or keeps coming back.
What causes vertigo?
Often, there is no known cause for BPPV. This is called idiopathic BPPV.
When there is a known cause, BPPV may be linked to a blow to the head. Less common causes include conditions that damage the inner ear. Rarely, the symptoms come from damage during ear surgery, or from lying on your back for an extended time, such as during surgery or bed rest [1].
How the inner ear controls balance
The vestibular labyrinth is a tiny system of structures deep inside the ear that manages balance. It includes three loop-shaped semicircular canals, which contain fluid and fine, hairlike sensors that detect how your head is moving.
Other structures, called otolith organs (the utricle and saccule), detect up-and-down, side-to-side, and front-to-back head movements. These organs hold tiny crystals that respond to gravity. Together, these hair cells help keep your eyes focused on a target while your head moves, and they help you stay balanced.
Why loose crystals make you dizzy
For many reasons, the crystals in the otolith organs can move out of place. When they do, they can fall into one of the semicircular canals. Certain head movements then cause the crystals to shift inside that canal.
That movement makes the semicircular canal sensitive to specific changes in head position. This is what causes the spinning sensation [1].
Who is at risk of vertigo?
The risk of BPPV is higher in people age 50 and older. But it can happen at any age. The condition is more common in people assigned female at birth. A head injury, or any other condition of the ear's balance organs, may raise the risk. The bone-thinning condition osteoporosis might also be a risk factor [1].
Risk factor | How it raises the risk |
Age 50 and older | The most common risk group, though it can occur at any age |
Being assigned female at birth | BPPV is more common in this group |
Head injury | A blow to the head can loosen the ear crystals |
Conditions of the ear's balance organs | Damage to balance structures raises risk |
Osteoporosis | The bone-thinning condition might be a risk factor |
Can vertigo cause complications?
BPPV rarely causes complications. The main concern is the dizziness itself. It can make you unsteady, which raises your risk of falling and of injury from falls [1].
This is why managing vertigo is not just about comfort. It is also about fall prevention, especially for older adults.
How is vertigo diagnosed?
To diagnose BPPV, a healthcare professional does a physical exam and moves your head into different positions. They watch for three things [2]:
Symptoms of dizziness that start from eye or head movements and then ease in less than one minute.
Dizziness with certain head movements, such as lying on your back with your head turned to one side and tipped slightly over the edge of the exam table.
Nystagmus, which is eye movement that happens on its own.
If the cause of your symptoms cannot be found, you may need more tests:
Test | What it does |
Electronystagmography (ENG) | Uses electrodes to record atypical eye movements (nystagmus) and show whether an inner ear condition causes the dizziness |
Videonystagmography (VNG) | Uses small cameras instead of electrodes for the same purpose |
MRI | Uses a magnetic field and radio waves to make images of your head and body, helping rule out other causes of vertigo |
How is vertigo treated?
BPPV may go away on its own within a few weeks or months. To help relieve it faster, a healthcare professional, audiologist, or physical therapist may treat you with a series of movements called the canalith repositioning procedure [2].
The canalith repositioning procedure
The goal of this treatment is simple. When tiny crystals called otoconia break loose and fall into the wrong part of the semicircular canals, the repositioning procedure moves them back to a part of the ear, the utricle, where they will not cause vertigo.
Done in the office, the procedure involves simple, slow head movements. There are several types of repositioning procedures a provider may use. You hold each position for about 30 seconds after the symptoms or atypical eye movements stop. The procedure most often works after just one or two treatments [2].
Your healthcare professional can also teach you how to perform the movements on yourself, so you can repeat them at home if needed.
When surgery is considered
Rarely, if the repositioning procedure does not work, a provider may suggest surgery. The operation may involve placing a bone plug to block the part of the inner ear that is causing the dizziness. The plug keeps the semicircular canal from responding to particle movements or to head movements at all [2].
Treatment | What happens | How well it works |
Watchful waiting | BPPV may clear on its own within weeks to months | Common, but treatment speeds recovery |
Canalith repositioning procedure | A series of slow, guided head movements moves loose crystals out of the canal | Most often works after one or two office visits |
Home repositioning | You learn to perform the movements yourself | Useful if symptoms return |
Surgery (rare) | A bone plug blocks the canal causing dizziness | Reserved for cases where repositioning fails |
What can you do at home to stay safe?
If dizziness from BPPV affects you, work with your healthcare professional to manage your symptoms. The following habits can help [2] [11]:
Be aware that you might lose your balance. Falling can cause serious injury.
Don't move in ways that bring on the symptoms. Learn your triggers and avoid them.
Sit down right away when you feel dizzy.
Use good lighting if you get up at night.
Walk with a cane if you are at risk of falling.
What should you do before your appointment?
Make an appointment with your main healthcare professional if you have symptoms of BPPV. They may send you to an ear, nose and throat specialist (an ENT) or to a neurologist, a doctor who specializes in the brain and nervous system [2].
What you can do to prepare:
Write down your symptoms, including when they started and how often they happen.
Note any recent blows to the head, including minor injuries.
Make a list of your key medical information, including any other conditions you are being treated for and the names and dosages of medicines, vitamins, or supplements you take.
Write down questions to ask your healthcare professional, so you make the most of your appointment time.
Questions worth asking at a first appointment:
What are the possible causes of my symptoms?
What tests do you suggest?
If these tests don't find the cause, what other tests might I need?
Do I need to follow any restrictions while waiting for a diagnosis?
Should I see a specialist?
Questions worth asking if you are referred to a specialist:
What treatments are most likely to help me feel better?
How soon after starting treatment might my symptoms improve?
If the first treatment doesn't work, what would you suggest next?
What self-care steps can help?
Do I need to restrict my activities, and for how long?
Am I at risk of this condition coming back?
What handouts or websites do you suggest for learning more?
Your healthcare professional will likely ask questions of their own, such as whether your symptoms come and go, how long they last, what seems to set them off, and whether they include vision issues, nausea, vomiting, headache, or hearing loss.
Conclusion and next steps
Vertigo is the sudden feeling of spinning or moving, and its most common cause, BPPV, comes down to tiny crystals in the inner ear drifting into the wrong spot. Each spell is brief, usually under a minute, and tied to head position. The condition is rarely dangerous, but the unsteadiness it causes raises your fall risk.
The main treatment is straightforward: a canalith repositioning procedure performed in the office, which moves the loose crystals out of the balance canal. Most people improve after one or two sessions, and the provider can teach you to repeat the movements at home. Because BPPV can return, ask your provider what to do if it does.
If your dizziness comes with warning signs like weakness, trouble talking, hearing loss, or passing out, seek care right away. Otherwise, a single office visit is often all it takes to find the cause and fix it.
Frequently asked questions
What is the difference between vertigo and dizziness? Vertigo is a specific type of dizziness: the sudden feeling of spinning or moving, as if you or the room are turning. General dizziness can also include feeling lightheaded, faint, or off balance without the spinning sensation.
Why does vertigo happen when I move my head? In BPPV, tiny crystals in the inner ear shift out of place and drift into a semicircular canal. When you move your head, the crystals move inside the canal and stimulate the ear's balance sensors, making your brain feel spinning [1].
How long does vertigo last? Each BPPV spell most often lasts less than a minute. The overall condition may go away on its own within a few weeks or months, though bouts can return. Treatment with repositioning movements usually resolves it much sooner [1] [2].
Is vertigo a sign of something serious? BPPV rarely signals a serious illness. However, vertigo with a new or severe headache, fever, double vision, hearing loss, trouble talking, weakness, passing out, or numbness needs medical attention right away [1].
Can vertigo come back after treatment? Yes. Bouts can disappear and then return. Your provider can teach you how to do the repositioning movements at home, and they can advise you on the risk of the condition coming back for your specific case [2].
