Vertigo happens when your brain receives conflicting signals about your body's position in space

Vertigo is not dizziness or lightheadedness. It is the sensation that you or the room around you is spinning, even when you are standing still. This happens because your inner ear, eyes, and the balance sensors in your body send mixed or incorrect messages to your brain about where you are and how you are moving. Your brain tries to make sense of these conflicting signals and produces the spinning sensation as a result.

The spinning feeling can last seconds, minutes, or hours depending on what is causing it. Some people feel it only when they move their head in a certain direction. Others feel it constantly. The sensation is real and physical—it is not anxiety or imagination, though anxiety can make it worse.

Key Takeaways

  • Vertigo results from your inner ear, eyes, or balance system sending conflicting signals to your brain about your position and movement.
  • Benign paroxysmal positional vertigo (BPPV) is the most common cause and happens when calcium crystals in your inner ear shift out of place.
  • Vestibulitis and labyrinthitis, usually caused by viral infections, inflame the inner ear and trigger spinning sensations that can last days or weeks.
  • Meniere's disease causes vertigo along with hearing loss and ear fullness, and typically affects one ear.
  • Less common causes include stroke, multiple sclerosis, and certain medications, which is why persistent vertigo requires medical evaluation.

Benign Paroxysmal Positional Vertigo (BPPV) — the most common cause

BPPV accounts for roughly half of all vertigo cases. Inside your inner ear are tiny calcium carbonate crystals called otoliths. These crystals normally sit in a specific chamber and help your brain sense which direction is up. When you hit your head, have an inner ear infection, or sometimes for no clear reason, these crystals break loose and float into the semicircular canals—the tubes that detect head movement.

When the loose crystals move, they send false signals about your head position. You feel the room spinning, usually when you turn your head, roll over in bed, or look up. The spinning typically lasts 10 to 60 seconds and stops when you hold your head still. BPPV is more common as you age and after head injuries, but it can happen to anyone.

The good news is that BPPV is treatable. A doctor can perform a simple maneuver—usually the Epley maneuver—that moves the crystals back to where they belong. Some people recover on their own within weeks as the body reabsorbs the loose crystals.

Vestibulitis and labyrinthitis — inflammation from infection

Vestibulitis is inflammation of the vestibular nerve, which carries balance information from your inner ear to your brain. Labyrinthitis is inflammation of the labyrinth itself, the fluid-filled structure in your inner ear. Both are usually caused by a viral infection—often the same virus that causes a cold or flu—though bacterial infections can also trigger them.

When the virus inflames these structures, they send scrambled signals about movement and position. You feel severe spinning, often accompanied by nausea, vomiting, and difficulty walking. Unlike BPPV, the spinning does not depend on head position—it is constant or nearly constant. The vertigo can last days or weeks and is often the worst symptom you experience.

Most cases resolve on their own as the inflammation subsides, though recovery can take weeks. A doctor may prescribe medication to reduce nausea and dizziness while your body heals. Physical therapy exercises can help your brain adapt to the conflicting signals and speed recovery.

Meniere's disease — vertigo with hearing changes

Meniere's disease is a disorder of the inner ear that causes vertigo along with hearing loss, tinnitus (ringing in the ear), and a feeling of fullness or pressure in the affected ear. The exact cause is not fully understood, but it appears to involve a buildup of fluid in the inner ear that disrupts balance and hearing signals.

Vertigo attacks in Meniere's disease are unpredictable and can be severe. They typically last 20 minutes to several hours and are often accompanied by nausea and vomiting. Between attacks, you may feel fine, or you may have constant mild dizziness. Meniere's disease usually affects only one ear, though both ears can be involved over time.

There is no cure, but treatments can reduce the frequency and severity of attacks. These include dietary changes (reducing salt and caffeine), diuretic medications, and in some cases, injections or surgery. A doctor who specializes in ear disorders can help determine whether you have Meniere's disease and what treatment options make sense for your situation.

Stroke and neurological conditions

Vertigo can be a sign of stroke, particularly if it comes on suddenly and is accompanied by other symptoms like facial drooping, arm weakness, slurred speech, or difficulty walking. Stroke-related vertigo usually does not improve on its own and requires emergency medical care. If you experience sudden severe vertigo with any of these other symptoms, call emergency services immediately.

Other neurological conditions that can cause vertigo include multiple sclerosis, migraines, and tumors affecting the brain or inner ear. These are less common causes, but they are important to rule out, especially if your vertigo is new, persistent, or accompanied by other neurological symptoms like vision changes, weakness, or numbness.

Medications and other triggers

Certain medications can cause vertigo as a side effect. Antibiotics (particularly aminoglycosides), some blood pressure medications, and chemotherapy drugs are known to damage the inner ear or affect balance. If you started a new medication shortly before your vertigo began, mention this to your doctor—switching medications or adjusting the dose may help.

Other triggers include head injuries, sudden changes in air pressure (from flying or diving), prolonged bed rest, and in some cases, anxiety or panic attacks. Migraines can also cause vertigo, sometimes without a headache. Identifying what triggered your vertigo helps your doctor narrow down the cause and recommend the right treatment.

When to see a doctor about vertigo

See a doctor if your vertigo is new, lasts more than a few days, or is severe enough to interfere with daily activities. Bring a description of what you experience: Does the room spin or do you feel like you are moving? Does it happen only with certain head movements or is it constant? Does it come and go or is it steady? This information helps your doctor identify the cause.

Seek emergency care if vertigo comes on suddenly and is accompanied by chest pain, severe headache, vision changes, weakness, numbness, or difficulty speaking. These can be signs of stroke or another serious condition that needs immediate attention.

Frequently Asked Questions

Can anxiety cause vertigo?

Anxiety and panic attacks can cause dizziness and a sensation of spinning, though true vertigo—the feeling that the room is spinning—is usually caused by a physical problem in the inner ear or brain. If you have anxiety and vertigo, both may be present. A doctor can help determine which is which.

Is vertigo permanent?

Most causes of vertigo are temporary. BPPV often resolves within weeks. Vestibulitis and labyrinthitis usually improve within days to weeks. Meniere's disease is chronic but manageable with treatment. Vertigo from stroke or serious neurological conditions requires urgent care and the outcome depends on the underlying cause.

Can you drive with vertigo?

No. Vertigo impairs your balance and spatial awareness, making driving unsafe for you and others. Do not drive until the spinning has stopped and you feel stable. If vertigo is frequent or chronic, discuss driving safety with your doctor.

What is the difference between vertigo and dizziness?

Dizziness is a general feeling of lightheadedness or unsteadiness. Vertigo is the specific sensation that you or the room is spinning. Dizziness can come from low blood pressure, dehydration, or anxiety. Vertigo usually comes from an inner ear or neurological problem.

Can you treat vertigo at home?

For mild BPPV, staying still and avoiding sudden head movements can help. For other causes, home rest may ease symptoms while your body heals, but you should see a doctor to confirm the cause. Some conditions, like stroke, require immediate medical care. Do not assume home treatment is safe without a diagnosis.
