Benign paroxysmal positional vertigo

Overview

Benign paroxysmal positional vertigo (BPPV) is a common inner ear problem that causes brief, intense spinning sensations (vertigo) when you move your head. It happens when tiny calcium crystals in your inner ear become dislodged and float into the wrong part of your ear canal, sending false signals to your brain about your head’s position.

Yes, it is the most common cause of vertigo, affecting about 2.4 percent of people at some point in their lives.

It can affect people of any age but is most common in adults over 60. Women are affected more often than men. You are also more likely to get it after a head injury or if you have an inner ear infection.

Symptoms

Common symptoms

• Brief spinning sensation triggered by rolling over in bed, tilting your head back, or bending forward.
• Feeling off-balance or unsteady.
• Nausea (feeling sick) or vomiting (being sick).
• Lightheadedness during or after the spinning.
• Difficulty focusing your eyes during an episode.

Symptoms in children

• May be harder to describe – they might just say they feel dizzy or wobbly.
• They might hold onto furniture or refuse to move their head.
• Nausea and vomiting are common, especially after moving in bed.
• They might seem irritable or cry during episodes.

Symptoms in older adults

• Higher risk of falling because of dizziness and imbalance.
• Episodes may be less intense but happen more often.
• May be mistaken for general aging or other conditions.
• Be extra cautious when getting out of bed or standing up.

Causes

Main causes

• Tiny calcium crystals (called otoconia) break loose from their usual place in your inner ear and float into the semicircular canals – these canals help you sense movement.
• When you move your head, the crystals move inside the canal and send false signals to your brain, making you feel like you are spinning even though you are still.

Risk factors

• Ageing – the structures in your ear naturally wear down over time.
• Head injury – even a mild bump can dislodge the crystals.
• Inner ear infection or inflammation (labyrinthitis).
• Prolonged bed rest or lying flat for a long time (e.g., after surgery).
• Migraine – some people with migraine are more prone to BPPV.

When to see a doctor

See a doctor urgently if:

• If you have vertigo along with the emergency symptoms listed above.
• If you faint or nearly faint during a vertigo spell.
• If you have a high fever, severe ear pain, or sudden hearing loss.

Book a routine appointment if:

• If vertigo keeps happening and it bothers you or affects your daily life.
• To get a proper diagnosis – a simple clinic test can confirm BPPV.
• If you are unsure whether your symptoms are due to BPPV or another condition.

Diagnosis

A doctor or nurse will ask about your symptoms and perform a simple test called the Dix-Hallpike maneuver. They will gently move your head and body into certain positions while watching your eyes for telltale jerking movements (nystagmus).

Tests that may be done

• Dix-Hallpike maneuver – the main test for BPPV.
• Sometimes a video goggles system (goggles that record your eye movements) is used to confirm the diagnosis.
• Imaging scans like an MRI or CT scan are usually not needed unless there are unusual symptoms.

What to expect at your appointment

The test takes only a few minutes. You might briefly feel dizzy during the maneuver, but it helps the doctor see which ear is affected and which type of BPPV you have. The test is safe and very reliable.

Treatment

Treatment for BPPV is very effective. The main approach is a series of head and body movements called canalith repositioning maneuvers (the most common is the Epley maneuver). These movements guide the dislodged crystals back into the correct part of the inner ear, where they no longer cause symptoms.

Self-care at home

• Avoid sudden head movements – especially rolling over quickly in bed, looking up, or bending forward.
• Sleep with your head slightly elevated on two pillows to keep the crystals from moving.
• Be careful when getting out of bed – sit on the edge for a moment before standing.
• Do not try the repositioning maneuvers at home unless a healthcare professional has shown you how – getting them wrong can make symptoms worse.

Medical treatments

A healthcare professional (such as a doctor, nurse, or physiotherapist) can perform repositioning maneuvers in the clinic. These maneuvers often work after one or two sessions and can resolve symptoms quickly. Some clinics also offer vestibular rehabilitation therapy – exercises that help your brain adapt to the problem. Medications for nausea (like antihistamines) may be prescribed for severe sickness but do not treat the underlying cause.

When is surgery considered?

Surgery is rarely needed. In very stubborn cases that do not respond to maneuvers, a small procedure called canal plugging (blocking the affected part of the ear canal) may be considered. This is only done in specialist centres and for severe, persistent BPPV.

Living with this condition

Living with BPPV can be frustrating, but many people find that their episodes become less frequent over time. You can manage day-to-day by being mindful of your head movements and making small changes to your routine, like sitting on the edge of your bed for a few seconds before standing up.

Lifestyle tips

• Sleep with an extra pillow to keep your head slightly raised.
• Avoid activities that require quick head movements, like certain yoga poses, gymnastics, or amusement park rides.
• Use a nightlight to help with balance if you get up during the night.
• If you feel a dizzy spell coming on, stop what you are doing and sit down or hold onto something steady until it passes.

Diet and exercise

There is no special diet for BPPV, but staying well-hydrated and eating regular meals can help prevent lightheadedness. Gentle exercise like walking or tai chi may improve your balance over time. Avoid exercise that involves head tilting or rolling until the condition resolves.

Mental health and emotional wellbeing

It is normal to feel anxious or worried about falls, especially if you have had severe episodes. Some people avoid certain activities out of fear. If these feelings are affecting your quality of life, talk to your doctor. If you ever feel overwhelmed, remember that support is available – you can call a mental health helpline in your country or speak to a trusted healthcare provider.

Prevention

BPPV cannot always be prevented, especially as it is often related to ageing. However, you can reduce your risk by protecting your head from injury – for example, wearing a helmet when cycling or skiing. If you have had BPPV before, you may be able to reduce recurrences by avoiding prolonged bed rest and staying active.

Complications

If left untreated

• Increased risk of falls and injuries, especially in older adults.
• Anxiety or avoidance of daily activities because of fear of vertigo.
• Rarely, persistent imbalance that can affect quality of life.

Long-term outlook

The outlook for BPPV is very good. Most cases resolve on their own within weeks or months. For those who need treatment, canalith repositioning maneuvers work in about 80 to 90 percent of cases. Even if BPPV returns, it can be treated again successfully. With proper management, most people can get back to their normal activities without lasting problems.
