Dizzy spells: getting a diagnosis
Recurrent dizzy spells nearly always have a findable cause - the timing, triggers and company they keep separate inner-ear, cardiovascular, migraine-related and functional causes far better than any scan.

Key facts
The essentials at a glance.
The symptoms to recognise, when to seek help, which specialist to see, and what treatment usually involves.
-
Duration is diagnostic: seconds suggest BPPV or blood pressure drops, hours suggest Ménière's or migraine
-
Triggers matter: position changes point to BPPV or orthostatic causes; visual environments to PPPD
-
Dizziness with palpitations or blackouts needs cardiac assessment
-
Specialist: a consultant audiovestibular physician; keep a diary of attacks before your appointment
Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
The word 'dizzy' covers spinning, floating, lightheadedness and unsteadiness, and each history detail narrows the field: spins of seconds on rolling in bed (BPPV); lightheadedness seconds after standing (orthostatic hypotension); spontaneous attacks of spinning lasting 20 minutes to hours with ear fullness (Ménière's) or with headache and light sensitivity (vestibular migraine); dizziness with palpitations or near-blackout (cardiac); and constant swaying amplified by supermarkets (PPPD).
Diagnosis and treatment routes
Assessment reproduces and measures what it can - positional testing, lying and standing blood pressure, eye movement examination, hearing tests - and adds vestibular function testing, cardiac monitoring or imaging only as the story directs. A dated diary of attacks, their duration, triggers and companions is genuinely the most powerful diagnostic instrument you can bring, and treatment then follows the specific diagnosis rather than a generic label. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial appointment with a private consultant is typically available within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a consultant audiovestibular physician. Your GP can refer you on the NHS, or you can arrange a private consultation directly.
A quiet reminder

Your GP knows your history and can tell you which parts apply to you. If in doubt, see them - and seek urgent care for any of the emergency symptoms described above.
Frequently asked
Common questions about Dizzy spells: getting a diagnosis.
Quick, plain-English answers to what people ask us most.
-
How do doctors diagnose the cause of dizzy spells?
Recurrent dizzy spells nearly always have a findable cause - the timing, specific triggers, and accompanying symptoms help separate inner-ear causes from cardiovascular, neurological, or other explanations during assessment.
-
What information is helpful for diagnosing dizzy spells?
Useful details include exactly what the dizziness feels like (spinning, lightheadedness, unsteadiness), how long episodes last, specific triggers (such as position changes or head movement), and any accompanying symptoms like hearing changes or headache.
-
What are common causes of recurrent dizzy spells?
Common causes include inner ear conditions (such as benign paroxysmal positional vertigo), blood pressure changes on standing, certain heart rhythm problems, and, less commonly, neurological conditions - each with a somewhat different typical pattern.
-
Is it dangerous to have recurrent dizzy spells?
Most causes are benign and treatable, but persistent or worsening dizzy spells should still be properly investigated, since some causes (though less common) can be more serious and benefit from prompt identification.
-
How is the specific cause of dizzy spells identified?
Diagnosis typically involves a detailed history, examination (including specific positional and balance tests), and, depending on findings, further tests such as blood pressure monitoring, hearing tests, or, occasionally, brain imaging.
-
How long does it take to get a diagnosis for dizzy spells?
Straightforward cases with a clear pattern may be diagnosed at the first consultation, while more complex presentations may need additional tests over a few weeks to reach a confident diagnosis.
-
Can dizzy spells be treated once the cause is found?
Yes, treatment is generally very effective once the specific cause is identified - for example, specific repositioning exercises for certain inner ear conditions, or medication adjustments for blood pressure-related causes.
-
What is benign paroxysmal positional vertigo (BPPV)?
BPPV is one of the most common causes of brief, positional vertigo (triggered by specific head movements), caused by small crystals becoming displaced within the inner ear, and it's often very effectively treated with specific repositioning manoeuvres.
-
Dizzy spells vs constant dizziness - does the pattern matter?
Yes, distinct, triggered episodes (dizzy spells) versus constant, ongoing dizziness point towards different types of causes, which is why describing the exact pattern and any triggers clearly to your doctor is genuinely helpful for reaching an accurate diagnosis.
-
When should I see a specialist about recurrent dizzy spells?
See an ENT specialist, neurologist, or balance clinic if dizzy spells are recurrent or affecting your daily life. A private specialist consultation is often available within about two weeks, compared with potentially longer NHS waiting times.
