Vertigo is usually caused by problems in your inner ear or brain, not by low blood pressure or standing up too fast

Vertigo—the sensation that the room is spinning around you—happens when your brain receives conflicting signals about your body's position and movement. Most of the time, the problem is in your inner ear, which contains fluid and sensors that tell your brain which way is up. When that system malfunctions, your brain thinks you're moving when you're not, or moving in a different direction than you actually are. Less often, vertigo comes from the brain itself, from your neck, or from medication you're taking.

The key distinction is that true vertigo is rotational—you feel like something is spinning, not just that you're lightheaded or unsteady. If the room feels like it's tilting or whirling, that's vertigo. If you just feel faint or off-balance without the spinning sensation, that's a different problem and usually has different causes.

Key Takeaways

  • Benign paroxysmal positional vertigo (BPPV) is the most common cause and happens when calcium crystals in your inner ear become dislodged and move into the wrong part of the canal.
  • Vestibular neuritis and labyrinthitis are viral infections of the inner ear that cause sudden, severe spinning that can last days or weeks.
  • Ménière's disease causes vertigo along with hearing loss and ear fullness, and the spinning attacks come and go unpredictably.
  • Migraines can trigger vertigo even when you don't have a headache, and it may be the only symptom you notice.
  • Some medications, head injuries, and problems with blood flow to the brain can also cause vertigo, so your doctor needs to know your full medical history.

Benign Paroxysmal Positional Vertigo (BPPV)

BPPV is the most common cause of vertigo, accounting for roughly half of all cases. It happens when tiny calcium carbonate crystals (called otoliths) that normally sit in one part of your inner ear become dislodged and float into the semicircular canals—the tubes that sense rotation. When you move your head, these crystals shift and send false signals to your brain about which direction you're moving.

The spinning usually starts suddenly when you move your head in a certain way—rolling over in bed, looking up, or bending down. The vertigo is intense but brief, often lasting only seconds to a minute. You may feel fine between episodes. BPPV can happen after a head injury, but often there's no clear reason why the crystals came loose. It's more common as you age.

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 over weeks or months, but the maneuver speeds recovery significantly.

Vestibular Neuritis and Labyrinthitis

These are viral infections that inflame the nerves or structures in your inner ear. Vestibular neuritis affects the nerve that sends balance signals to your brain; labyrinthitis affects the inner ear itself. Both cause sudden, severe vertigo that often comes with nausea and vomiting. The spinning is constant rather than triggered by head movement, and it can be so intense that you can't stand or walk without support.

The vertigo usually peaks within the first day or two and then gradually improves over a week or two, though some people take longer to recover fully. You may feel unsteady or have mild dizziness for weeks after the acute spinning stops. These infections are usually viral (sometimes following a cold or flu) and cannot be treated with antibiotics, though your doctor may prescribe medication to manage nausea and dizziness while your body heals.

Ménière's Disease

Ménière's disease is a disorder of the inner ear that causes episodes of vertigo along with hearing loss, tinnitus (ringing in the ear), and a feeling of fullness or pressure in the affected ear. The attacks come without warning and can last anywhere from 20 minutes to several hours. Between attacks, you may feel completely normal, or you may have ongoing hearing loss and tinnitus.

The cause isn't fully understood, but it appears to involve a buildup of fluid in the inner ear. Ménière's usually affects only one ear and often develops in people in their 40s or 50s. There's no cure, but various treatments—from dietary changes to medications to surgery—can help reduce the frequency and severity of attacks. Your doctor will work with you to find what works best.

Migraine-Associated Vertigo

Vertigo can be a symptom of migraine, even if you don't have a headache. Some people experience spinning as part of their migraine aura (the warning signs that come before a migraine), while others have vertigo as their main migraine symptom. The spinning may last minutes to hours and can be as disabling as the headache itself.

Migraine-associated vertigo is often overlooked because people don't connect dizziness to migraines. If you have a history of migraines and you're experiencing new or worsening vertigo, mention this to your doctor. Migraine preventive medications can reduce how often these episodes happen.

Medication Side Effects and Other Medical Causes

Some medications can cause vertigo as a side effect, including certain antibiotics, blood pressure drugs, and seizure medications. If you started a new medication shortly before your vertigo began, that timing matters—tell your doctor. They may be able to switch you to a different drug or adjust your dose.

Other medical causes include head injuries (which can damage the inner ear or brain structures involved in balance), stroke or transient ischemic attack (TIA), multiple sclerosis, and problems with blood flow to the brain. Cervical vertigo—caused by problems in the neck—is less common than people think but can happen after whiplash or neck injury. Your doctor will take your medical history, ask about recent injuries or illnesses, and may order imaging or other tests to rule out serious causes.

When to See a Doctor About Vertigo

See a doctor if you experience vertigo for the first time, if it's severe, or if it lasts more than a few hours. Also seek care if vertigo is accompanied by weakness, numbness, difficulty speaking, chest pain, or severe headache—these can be signs of stroke or another serious condition. If you have mild vertigo that comes and goes, you should still mention it at your next regular appointment.

Your doctor will ask detailed questions about when the spinning started, what triggers it, how long it lasts, and what other symptoms you have. They may perform simple tests in the office to check your balance and eye movements. Depending on what they find, you may need imaging (like an MRI) or referral to an ear, nose, and throat specialist or neurologist.

Frequently Asked Questions

Can vertigo go away on its own?

Yes, depending on the cause. BPPV often improves within weeks without treatment. Vestibular neuritis usually resolves over time as your brain compensates for the inner ear damage. Other causes like Ménière's disease or migraine-associated vertigo may need treatment to manage symptoms, but they don't always require it.

Is vertigo a sign of something serious like a stroke?

Vertigo alone is usually not a sign of stroke, but it can be. Stroke-related vertigo typically comes with other symptoms like weakness on one side of your body, slurred speech, or facial drooping. If you have vertigo plus any of these symptoms, seek emergency care immediately. If you have only vertigo, it's still worth seeing a doctor to rule out serious causes.

Why does my vertigo get worse when I move my head?

Head movement makes vertigo worse in BPPV because moving your head shifts the loose crystals in your inner ear, triggering the spinning sensation. In other causes like vestibular neuritis, head movement may also worsen dizziness because your brain is already struggling to process balance signals. Your doctor can determine which cause fits your situation.

Can stress or anxiety cause vertigo?

Stress and anxiety can make existing vertigo feel worse and can cause dizziness or lightheadedness, but they don't typically cause true rotational vertigo. If you're experiencing spinning sensations, the underlying cause is usually a physical problem in your inner ear or brain, not anxiety alone. That said, anxiety about vertigo can make recovery slower.

What's the difference between vertigo and dizziness?

Vertigo is the specific sensation that the room is spinning or that you're spinning. Dizziness is a broader term that includes lightheadedness, unsteadiness, and feeling faint. Vertigo has different causes than other types of dizziness, and treatment depends on which one you have. Telling your doctor exactly what you feel—spinning versus lightheadedness—helps them narrow down the cause.
