Vertigo: BPPV and other causes, the Epley maneuver, and red flags
Last updated September 3, 2026.
Vertigo is the false sense that you or the room is spinning, and the most common cause is one of the most fixable problems in medicine. Benign paroxysmal positional vertigo (BPPV) happens when tiny crystals in the inner ear drift into the wrong canal, and it produces short, violent spins with head movements. A guided set of head maneuvers clears most cases, often in one or two sessions.
What kind of dizzy are you?
The distinction matters, so be precise with yourself. Vertigo is rotation: the room spins or tilts. Lightheadedness, the about-to-faint floating feeling, is usually blood pressure, dehydration, low blood sugar, or anxiety, and unsteadiness without spinning points toward medication effects, vision, or nerve problems in the feet. BPPV has a classic script: spinning lasting seconds to under a minute, triggered by rolling over in bed, lying down, looking up, or bending over, sometimes with nausea, then completely fine between episodes. Constant spinning for days after a viral illness suggests vestibular neuritis. Recurrent attacks lasting 20 minutes to hours with muffled hearing, tinnitus, and ear fullness suggest Meniere's disease.
What actually helps?
- The Epley maneuver for BPPV: a specific sequence of head and body positions that rolls the loose crystals out of the canal. It resolves most cases within one or two rounds, and once a clinician confirms the side and shows you the steps, you can repeat it at home. Feeling briefly vertiginous during the maneuver is expected and is actually a sign it is engaging the problem.
- Brandt-Daroff exercises as the gentle option: repeated side-lying position sequences done at home several times a day; less effective per session than Epley but simple and safe, and useful for residual unsteadiness.
- Keep moving, carefully: vestibular recovery is use-driven, so normal activity (with fall-proofing: good lighting, no rushing, handrails) retrains the brain faster than lying still. Formal vestibular rehabilitation with a physiotherapist is the fix for lingering imbalance.
- Medication is a short bridge only: drugs like prochlorperazine or antihistamine motion-sickness tablets blunt severe nausea and spinning for the first few days of an acute episode, but taking them longer than a few days actually slows the brain's compensation.
- Meniere's is managed differently: salt restriction, and sometimes prescription diuretics or specialist procedures, so the ear-fullness-plus-hearing-change pattern deserves an ENT assessment rather than Epley at home.
When is it an emergency?
Vertigo with any of the following can be a stroke and means calling emergency services immediately: double vision, slurred speech, trouble swallowing, weakness or numbness on one side, inability to walk straight, or a sudden severe headache. Sudden hearing loss in one ear with vertigo is a same-day emergency for a different reason: sudden sensorineural hearing loss is treatable mainly within the first days. New vertigo with fainting, chest pain, or a very irregular heartbeat also needs urgent assessment. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
What is the difference between vertigo and dizziness?
Dizziness is the umbrella word, and the subtype points at the cause. Vertigo specifically means a false sense of movement, usually spinning, and comes from the inner ear balance system or the brain areas that process it. Lightheadedness, the woozy, about-to-faint feeling, usually comes from blood pressure drops, dehydration, low blood sugar, or anxiety. Unsteadiness, feeling off-balance without spinning, suggests medication effects, vision problems, or nerve loss in the feet. Telling your doctor which of the three you have is more useful than any test.
What is BPPV?
Benign paroxysmal positional vertigo: the most common cause of vertigo. Tiny calcium crystals (otoconia) that belong in one part of the inner ear break loose and drift into a semicircular canal, where they slosh with head movement and send false spinning signals. It produces brief, intense spins with position changes: rolling in bed, lying down, looking up. It is more common with age, after head knocks, and after ear infections, and it is benign in the medical sense: miserable but not dangerous, and very treatable.
What is the Epley maneuver, and does it really work?
It is a sequence of four head and body positions, held about 30 seconds each, that uses gravity to walk the loose crystals out of the canal they fell into. It has some of the best evidence in all of medicine: most BPPV cases resolve after one or two rounds. A clinician should do it first, both to confirm which ear and canal are involved (doing it on the wrong side wastes the effort) and to teach you the steps. Brief spinning during the maneuver is normal and expected.
How long does vertigo last?
It depends entirely on the cause. BPPV episodes last seconds to under a minute each, and the condition itself resolves with maneuvers or on its own over weeks to months. Vestibular neuritis hits hard for two to three days of constant spinning, then fades over weeks as the brain compensates. Meniere's disease causes attacks of 20 minutes to several hours that recur. Migraine-related vertigo follows the migraine pattern. The duration and trigger pattern is the diagnostic map, which is why doctors ask about it so specifically.
Is vertigo a sign of something serious?
Usually not. The large majority of vertigo is BPPV, neuritis, migraine, or Meniere's, none of which are dangerous. The serious minority announces itself with company: double vision, slurred speech, one-sided weakness or numbness, trouble walking straight, sudden severe headache, or sudden hearing loss in one ear. Vertigo alone, especially the classic brief positional type, almost never signals a brain problem. New vertigo in someone over 60 with stroke risk factors still deserves a proper examination rather than an assumption.
Can stress and anxiety cause vertigo?
Stress and anxiety cause dizziness and lightheadedness easily (hyperventilation and adrenaline do that directly), and they amplify awareness of any existing balance problem, but they do not cause true spinning vertigo on their own. The more common tangle is the reverse: a vertigo episode is frightening, the fear makes people avoid head movements, and avoidance slows recovery. Persistent postural-perceptual dizziness, a chronic off-balance state often triggered by a vertigo episode plus anxiety about it, is real, well described, and treatable with vestibular rehabilitation and anxiety treatment together.
