Informed by recognized medical guidance
Overview
Dizziness is a feeling of being lightheaded, unsteady, or like the room is spinning. It is not a disease itself but a symptom that can have many causes. When dizziness is persistent or severe, a specialist may perform tests to find the underlying reason.
Key facts
- Dizziness is one of the most common reasons people visit a doctor.
- Most causes of dizziness are not dangerous, but some need medical attention.
- Specialist tests help identify inner ear problems, neurological issues, or other conditions.
- Treatment is often effective once the cause is known.
Yes, dizziness is very common. About 1 in 4 people will experience significant dizziness at some point in their lives.
Dizziness can affect people of all ages, but it becomes more common as people get older. It can also affect children, especially with ear infections, and young adults due to migraines or anxiety.
Symptoms
- Dizziness with chest pain, shortness of breath, or severe headache
- Dizziness with sudden weakness or numbness on one side of the face, arm, or leg
- Dizziness with slurred speech or confusion
- Dizziness with loss of consciousness
- ⚠Dizziness after a head injury
- ⚠Dizziness that is severe and prevents you from walking
- ⚠Dizziness with a fever or stiff neck
- ⚠Dizziness that does not go away after a few hours
Common symptoms
- Feeling like you or the room is spinning (vertigo)
- Lightheadedness or feeling faint

Symptoms in older adults
- Sudden feeling of unsteadiness when standing up
- Fear of falling
- Dizziness with turning the head or looking up
- Fainting or near-fainting spells
Causes
Main causes
- Inner ear problems, such as benign paroxysmal positional vertigo (BPPV), labyrinthitis, or Meniere's disease
- Migraine – vestibular migraine can cause dizziness without headache
- Low blood pressure when standing up (orthostatic hypotension)
- Heart rhythm problems (arrhythmias)
- Anxiety or panic attacks
- Medication side effects
- Neurological conditions, such as multiple sclerosis or stroke (rare)
Risk factors
- Age over 65
- History of ear infections or head injury
- Taking multiple medications
- Migraine history
- Anxiety or depression
- Dehydration or not eating enough
When to see a doctor
See a doctor urgently if:
- Dizziness with any emergency symptoms listed above
- Dizziness after a fall or head injury
- Dizziness that prevents you from standing or walking
Book a routine appointment if:
- Dizziness that keeps coming back or lasts longer than a few days
- Dizziness that interferes with your daily activities
- Dizziness accompanied by hearing loss or ringing in the ears
Diagnosis
A doctor will ask about your symptoms, medical history, and perform a physical exam. If the cause is not clear, or if dizziness is severe, you may be referred to a specialist (such as an ear, nose, and throat doctor or a neurologist) who can order specific tests.
Tests that may be done
- Videonystagmography (VNG): a test that uses video goggles to record eye movements and check inner ear function.
- Audiometry (hearing test): to check if hearing loss is related to dizziness.
- Posturography: a test that measures your balance on a moving platform.
- Head impulse test: a quick head movement test to assess the vestibular system.
- Imaging tests: such as MRI or CT scans to look at the brain and inner ear structures.
- Blood tests: to check for anaemia, infection, or metabolic problems.
- Electrocardiogram (ECG): to check heart rhythm.
What to expect at your appointment
Most tests are painless and done in an outpatient clinic. The VNG may make you feel dizzy for a short time, but this is normal and usually passes quickly. Your specialist will explain each test before it happens.
Treatment
Treatment for dizziness depends on the cause. Once a diagnosis is made, your doctor can recommend the best approach. Many conditions can be managed with simple treatments or exercises.
Self-care at home
- Sit or lie down immediately if you feel dizzy to avoid falling.
- Move slowly when changing positions, especially from lying to standing.
- Drink plenty of water and avoid dehydration.
- Avoid sudden head movements.
- Use a walking aid if needed for balance.
Medical treatments
Treatment may include medication to reduce nausea or control symptoms of vertigo (such as antihistamines or vestibular suppressants). For inner ear problems like BPPV, a doctor can perform a series of head movements (canalith repositioning, also called the Epley manoeuvre) to dislodge crystals. Vestibular rehabilitation therapy (balance exercises) can help train your brain to compensate for inner ear issues. If an infection is the cause, antibiotics may be prescribed. For migraines, treatments include lifestyle changes and preventive medication.
When is surgery considered?
Surgery is rarely needed for dizziness. It may be considered for severe Meniere's disease or certain tumours affecting the balance nerve, but this is uncommon.
Living with this condition
Living with dizziness can be challenging, but many people manage well with simple adjustments. Keep your home clutter-free, use good lighting, and avoid rugs that can trip you. Allow extra time for tasks and rest when needed.
Lifestyle tips
- Avoid triggers like alcohol, caffeine, and tobacco.
- Get enough sleep and manage stress.
- Consider using a walking stick or cane for extra stability.
- Tell family and friends about your dizziness so they can help.
Diet and exercise
Eat regular, balanced meals to keep blood sugar stable. Stay hydrated. Exercises that improve balance, such as tai chi or vestibular rehabilitation, can be very helpful. Ask your doctor or physiotherapist for a safe exercise plan.
Mental health and emotional wellbeing
Chronic dizziness can cause anxiety and fear of falling. It is normal to feel worried, but talking to a counsellor or joining a support group can help. Cognitive behavioural therapy (CBT) is effective for some people.
Prevention
Not all dizziness can be prevented, but you can lower your risk. Stay active, eat well, and avoid sudden head movements. If you have a known condition like migraine or low blood pressure, follow your treatment plan.
Vaccines
Some causes of dizziness, such as labyrinthitis from flu or other infections, can be reduced by staying up to date with recommended vaccinations. Ask your doctor about vaccines that might be right for you.
Complications
If left untreated
- Falls and injuries, including fractures or head trauma
- Persistent disability or inability to work or drive
- Increased risk of anxiety and depression
- Worsening of underlying conditions, such as heart problems or stroke
Long-term outlook
The outlook for dizziness is generally very good. With the right diagnosis and treatment, most people improve significantly. Even chronic dizziness can often be managed effectively with balance exercises and lifestyle changes, allowing you to live a full and active life.
