Benign Paroxysmal Positional Vertigo Bppv

Overview

BPPV is a common inner ear problem that causes brief, intense episodes of dizziness or vertigo (a spinning sensation) when you move your head in certain ways. It happens when tiny crystals of calcium carbonate, which help control balance, move into parts of the inner ear where they shouldn't be.

Yes, BPPV is very common. Around one in 50 people will experience it at some point in their lives, and it becomes more common as you get older.

It can affect anyone, but it is most likely to appear in adults over 50. It is also more common in women than in men.

Symptoms

Common symptoms

• Sudden, brief spinning sensation when you turn your head, sit up, or lie down.
• Feeling off-balance for a few minutes after the spinning stops.
• Nausea (feeling sick) or sometimes vomiting during an episode.
• Uncontrolled eye movements (nystagmus) during a dizzy spell.

Symptoms in children

• Children can get BPPV, but it is rare. They may describe a feeling of 'the world moving' or holding onto furniture to keep steady.
• They may have headaches or feel sick during episodes.

Symptoms in older adults

• Older adults may have less obvious spinning and instead feel unsteady or lose balance, making falls more likely.
• Episodes may last longer, but treatment is still effective.

Causes

Main causes

• The inner ear contains tiny calcium carbonate crystals that help you sense movement. Sometimes these break loose and float into a fluid-filled tube called the semicircular canal, sending false 'I am spinning' signals to the brain.
• Often there is no known cause (called 'idiopathic').
• It can follow a head injury, whiplash, or a viral infection of the inner ear.

Risk factors

• Being over 50 years old.
• Being female.
• A previous head injury.
• Prolonged bed rest or staying very still for long periods.
• Having another inner ear disorder, such as Meniere's disease.

When to see a doctor

See a doctor urgently if:

• See a doctor the same day if you have vertigo with hearing loss, ear ringing, or symptoms that are new and getting worse.
• Also see a doctor promptly if you have an underlying heart condition or are taking blood-thinning medicine and develop prolonged dizziness.

Book a routine appointment if:

• Make an appointment to see your GP or nurse practitioner if you have repeated episodes of brief dizziness, even if they go away on their own.

Diagnosis

A doctor can often diagnose BPPV by listening to your story and carrying out a simple physical test. You do not usually need scans or blood tests for typical BPPV.

Tests that may be done

• The Dix-Hallpike test, where the doctor moves your head to certain positions while you lie on the bed, to see if it triggers vertigo and tell-tale eye movements.
• Sometimes an MRI or CT scan is done if the doctor suspects another cause, such as a problem in the brain.

What to expect at your appointment

The doctor will ask you to describe exactly what you feel and when it happens. They will examine your eyes, ears, and balance. The tests are quick, but the Dix-Hallpike test may bring on a short episode of vertigo. Tell the doctor if you are anxious about this so they can help you through it.

Treatment

The most effective treatment is a series of guided head and body movements, called canalith repositioning or the Epley maneuver. These movements use gravity to move the loose crystals back to a tiny area of the inner ear where they cause no trouble. In many cases, one session eases symptoms.

Self-care at home

• Keep your head still during an episode — stay seated or lie down until the spinning stops.
• Move slowly when turning in bed or getting up from a chair.
• Use an extra pillow at night to keep your head slightly raised.
• Sleep with the affected ear uppermost, if you know which side it is.

Medical treatments

In addition to the repositioning movements, a doctor may discuss medicines that help with nausea — but these do not fix the underlying problem and are only used for a short time. Always ask your doctor or pharmacist for advice on any medicine.

When is surgery considered?

Surgery is very rarely needed. It may be considered only for severe, long-standing BPPV that has not improved with repositioning and physical therapy. Your doctor will explain all the risks and benefits if this is ever an option.

Living with this condition

Most people improve within a few days to weeks. Between episodes, you may feel a bit off-balance, but this usually settles. Try to keep a normal routine; avoid quick head movements and sudden turns, especially when bending down.

Lifestyle tips

• Sleep with your head slightly propped up on extra pillows.
• Avoid bending over to pick things up — bend your knees instead.
• When you get out of bed in the morning, sit on the edge of the bed for a moment before standing.
• Arrange your home to reduce the risk of falls: remove loose rugs, keep rooms lit, and install grab bars if needed.

Diet and exercise

There is no specific diet for BPPV, but staying hydrated and eating normally can help prevent dizziness from low blood sugar. Gentle exercises like walking are safe once you feel steady. Your doctor or physiotherapist can also teach you balance exercises that help your brain adapt.

Mental health and emotional wellbeing

Having repeated vertigo can make you feel anxious, worried, or even depressed, especially if you are afraid of falling or having an episode in public. These feelings are normal. Talk to your doctor about them, and remember that effective treatment exists.

Prevention

BPPV cannot always be prevented, especially when there is no obvious cause. But you can lower the risk of the falls and injuries that can bring on BPPV by keeping your home safe, staying active, and moving carefully. If you have had BPPV before, learning the repositioning movements from a professional may help you manage a future episode early.

Complications

If left untreated

• Episodes can continue, leading to daily dizziness and a higher risk of falling and fracturing a bone.
• Persistent dizziness can interfere with work, driving, and hobbies, and may cause anxiety or depression.

Long-term outlook

The outlook is very good. Most people get better with simple repositioning movements, and many feel completely back to normal within a few weeks. Even if it comes back, the treatment is still effective. Very few people need surgery, and serious harm is extremely rare.
