BPPV

What Is BPPV?

BPPV is a mechanical disorder of the inner ear that affects balance. It occurs when tiny calcium carbonate crystals (called otoconia) become dislodged and move into one of the semicircular canals of the inner ear.

These canals are responsible for detecting head movement. When the crystals move incorrectly, they send false signals to the brain, causing vertigo.

What Does “Benign Paroxysmal Positional Vertigo”

Mean?

• Benign – Not life-threatening

• Paroxysmal – Sudden, brief episodes

• Positional – Triggered by changes in head position

• Vertigo – A spinning sensation

Symptoms of BPPV

1. Vertigo Triggered by Movement

The hallmark symptom is brief episodes of spinning, typically lasting:

• A few seconds to under a minute

Common triggers include:

• Rolling over in bed

• Looking up or down

• Getting in or out of bed

• Tilting the head back (e.g. at the dentist or hairdresser)

2. Nystagmus (Involuntary Eye Movements)

• Rapid, jerking eye movements during an episode

• Often observed during clinical testing

3. Nausea

• May accompany vertigo

• Usually mild but can be more severe in some cases

What BPPV Does NOT Usually Cause

• Hearing loss

• Tinnitus

• Persistent dizziness (between episodes)

This helps distinguish BPPV from conditions like Ménière’s disease.

What Causes BPPV?

BPPV occurs when otoconia become displaced from their normal position in the utricle and enter the semicircular canals.

Common Causes:

• Age-related degeneration (most common)

• Head injury or trauma

• Inner ear infections (vestibular neuritis/labyrinthitis)

• Prolonged bed rest

• Post-surgical changes

In many cases, there is no obvious cause (idiopathic BPPV).

Who Is Most at Risk?

• Adults over 50 years old

• More common in women

• People with previous inner ear disorders

• Those with a history of head injury

How Is BPPV Diagnosed?

BPPV is diagnosed based on history and positional testing.

Dix-Hallpike Test

The gold standard diagnostic test:

• You are moved quickly from sitting to lying with your head turned

• If BPPV is present, this triggers:

  • Vertigo

  • Characteristic nystagmus

This helps identify:

• Which ear is affected

• Which semicircular canal is involved

Types of BPPV

BPPV can affect different canals:

• Posterior canal (most common)

• Horizontal canal

• Anterior canal (rare)

Correct identification is essential for effective treatment.

BPPV Treatment: Highly Effective and Fast

Unlike many vestibular disorders, BPPV can often be treated quickly and successfully.

1. Repositioning Manoeuvres

These are specific head movements designed to move the crystals back to where they belong.

Epley Manoeuvre

• Most commonly used treatment

• Highly effective for posterior canal BPPV

• Often resolves symptoms in 1–2 sessions

Semont Manoeuvre

• Alternative technique

• Useful in certain cases

Barbecue Roll (for horizontal canal BPPV)

• Used for less common variants

2. Post-Treatment Advice

After treatment, you may be advised to:

• Avoid lying flat for a few hours

• Sleep slightly elevated

• Be cautious with sudden head movements

(Note: strict restrictions are less commonly required now, depending on clinician preference.)

3. Vestibular Rehabilitation

If symptoms persist:

• Balance exercises may help

• Useful in recurrent or complex cases

4. Medication

Medication is not a primary treatment for BPPV:

• May help nausea temporarily

• Does not fix the underlying problem

How Long Does BPPV Last?

• Episodes last seconds to under a minute

• The condition itself may persist until treated

• Many cases resolve quickly with manoeuvres

• Some may recur weeks, months, or years later

Is BPPV Dangerous?

BPPV is not life-threatening, but it can increase the risk of:

• Falls

• Injury (especially in older adults)

Prompt treatment significantly reduces this risk.

Can BPPV Come Back?

Yes—recurrence is relatively common.

• Around 15–50% of people experience recurrence

• May occur months or years later

• Usually responds well to repeat treatment

Living With BPPV

Practical Tips:

• Move slowly when changing positions

• Sit on the edge of the bed before standing

• Ensure good lighting at night

• Avoid sudden head movements during active episodes

When to Seek Help

You should seek professional assessment if you experience:

• Recurrent vertigo triggered by movement

• Dizziness when lying down or turning in bed

• Balance problems affecting daily life

Seek Urgent Medical Attention If:

• Vertigo lasts longer than a few minutes continuously

• You have hearing loss, double vision, weakness, or difficulty speaking

• Symptoms are not position-dependent

These may indicate a different, more serious condition.

Final Thoughts

BPPV is one of the most treatable causes of vertigo. Although symptoms can feel intense, the condition is usually straightforward to diagnose and manage with the right expertise.

If you’re experiencing brief episodes of vertigo triggered by head movements, effective treatment may be simpler—and faster—than you expect.
