Also called: Vestibular hypofunction; unilateral vestibular loss

Exercise is the main treatment Balance Stretch

Dizziness, unsteadiness and a world that seems to move when you turn your head. The balance organ on one side is under-reporting, and the only thing that fixes it is deliberately provoking the symptoms until the brain recalibrates.

How common: A leading cause of chronic dizziness; dizziness affects 15-20% of adults annually

What it is

The vestibular system in each inner ear reports head movement. When one side is damaged or under-functioning, the two sides disagree, and the brain interprets the mismatch as movement that is not happening - producing vertigo, unsteadiness and visual disturbance on head movement.

The recovery mechanism is central compensation: the brain learns to reinterpret the asymmetric signal. That learning only happens with exposure, which means vestibular rehabilitation deliberately provokes symptoms in a graded way. It is counterintuitive, it is uncomfortable, and it is by far the most effective treatment - avoidance and vestibular sedative medication both prevent the compensation from happening.

What it feels like

  • Unsteadiness, particularly walking in the dark or on uneven ground
  • The world seeming to bounce or blur when you turn your head or walk
  • Dizziness provoked by head movement rather than present constantly
  • Nausea with movement, and exhaustion from concentrating on staying upright
  • Worse in visually busy environments - supermarkets, crowds, scrolling screens

What causes it

Most people have more than one of these at once, and they feed each other. Read the list looking for the two or three that sound like your week rather than for the one true answer — the ones that describe you are the ones worth acting on.

Vestibular neuritis or labyrinthitis
A viral or post-viral inflammation of the vestibular nerve produces sudden severe vertigo lasting days, followed by weeks or months of unsteadiness as compensation occurs. It is the commonest cause of unilateral loss.
Meniere's disease
Recurrent episodes of vertigo with hearing loss, tinnitus and a sense of fullness in the ear. It causes progressive vestibular loss over years and needs specific medical management.
Benign paroxysmal positional vertigo
Crystals displaced into a semicircular canal produce brief intense vertigo on specific head positions. It is extremely common, it is not vestibular weakness, and it is cured by a repositioning manoeuvre in minutes - which is why distinguishing it matters enormously.
Ototoxic medication
Gentamicin and related antibiotics can damage both vestibular systems, producing a bilateral loss with severe unsteadiness and visual disturbance on movement.
Age-related vestibular decline
Vestibular hair cells are lost with age, contributing to the general unsteadiness of later life and to fall risk.
Head injury
Concussion and skull base injury frequently damage vestibular function, and vestibular symptoms are a major component of persistent post-concussion problems.
Acoustic neuroma
A benign tumour on the vestibular nerve produces gradual unilateral loss with hearing changes. Progressive one-sided symptoms deserve investigation.
Avoidance of movement
Understandable and the main obstacle to recovery. Compensation requires exposure to the movements that provoke symptoms, so avoiding them prevents the brain from adapting.
Long-term vestibular sedative medication
Drugs like prochlorperazine are useful for a few days of acute vertigo and actively prevent compensation if continued. Long-term use is a common and correctable barrier to recovery.
Anxiety
Dizziness is frightening and anxiety amplifies the perception of imbalance. Persistent postural-perceptual dizziness is a recognised condition where this becomes the dominant driver.

Who tends to get it

  • Anyone who has had an episode of severe vertigo lasting days
  • People taking prochlorperazine or similar for more than a few days
  • Older adults, in whom vestibular function declines
  • Anyone who has had a head injury or concussion
  • People who have received gentamicin or related antibiotics

What makes it worse, and what settles it

Makes it worse

  • Avoiding head movement, which prevents the compensation that would fix it
  • Long-term vestibular sedative medication
  • Staying still and resting, which feels right and delays recovery
  • Visually complex environments before the brain has adapted
  • Fatigue and poor sleep, which reduce the compensation available

Settles it

  • Vestibular rehabilitation exercises - gaze stabilisation and habituation - done daily and deliberately provoking mild symptoms
  • Getting the diagnosis right, since positional vertigo is cured by a manoeuvre rather than by exercises
  • Balance training on progressively more challenging surfaces
  • Stopping vestibular sedatives after the first few days
  • Returning to normal visual environments gradually rather than avoiding them

What actually helps

The short version: Reduced or asymmetric vestibular input; the brain must be retrained through repeated exposure to the movements that provoke symptoms

Strength work: Neck; Glutes: Med; Legs: Quads for the balance component

Stretching: Neck - a stiff neck compounds the problem

Massage: Neck & Shoulders

Also worth doing: Vestibular rehabilitation: gaze stabilization drills, habituation exercises and progressive balance work. Symptoms must be provoked mildly for adaptation to happen

What the evidence says: Vestibular rehabilitation is genuinely exercise therapy and it is first-line with strong evidence. Distinct from BPPV, which needs a maneuver - and distinguishing the two is what makes the recommendation safe.

The qFIT routine for this

Ready-made routineMovement for Neurological Conditions

qFIT already has this one built. It runs massage first, then stretching, then strength — the order that works on a body that is already sore — and every activity in it carries the reason it is there.

The button below opens your Checklist with this routine already selected, so instead of your whole list you land on just its Categories, Targets and Exercises, each with its checkbox, ready to tick as you work through them.

Get it checked if…

Dizziness with hearing loss, double vision, slurred speech or weakness is not vestibular - emergency. Brief spinning on rolling over is BPPV and needs a repositioning maneuver instead

And whatever the body part: chest pain or unusual breathlessness on exertion; a fever alongside the pain; unexplained weight loss; pain that is constant and unrelated to how you move; new numbness, weakness or loss of bladder or bowel control; or one calf that is swollen, warm and painful. Any of those, stop and get assessed.

How it usually goes

Vestibular rehabilitation is highly effective, with most people improving substantially over six to twelve weeks of daily exercises. Compensation is a learning process and it requires the symptoms to be provoked, which is why it needs explaining properly or people stop. Sudden vertigo with new hearing loss, with double vision, weakness, slurred speech or a severe headache is a different and urgent picture that needs emergency assessment rather than exercises.

Others the same routine covers

These share the Movement for Neurological Conditions routine, so the work is the same. If one of them also sounds like you, that is a reason to expect more from it, not less.

This is general information, not a diagnosis, and it cannot examine you. If it matches you, use it to ask better questions of a clinician rather than to replace one.
