What Causes Vertigo? Why the Room Spins and When to Worry

You roll over in bed and the ceiling suddenly lurches sideways. Or you tip your head back to reach a high shelf and end up gripping the counter instead. Vertigo is one of the most unsettling things a body can do, and it is a common reason people in Boynton Beach, Delray Beach and across Palm Beach County end up in an emergency room. The reassuring part: most vertigo starts in the inner ear, not the brain, and the most common causes are very treatable once someone figures out which one you have.

Vertigo, lightheaded or off balance? Not all “dizzy” is the same

People use the word dizzy for several very different feelings, and doctors sort them apart because each one points to different causes:

• Vertigo: the room spins, tilts or sways, or you feel like you are moving when you are still. This usually comes from the balance system in the inner ear, and less often from the brain.
• Lightheadedness: a faint, woozy feeling, as if you might pass out. Common culprits include dehydration, a drop in blood pressure when you stand up, medication side effects, low blood sugar and heart rhythm problems.
• Disequilibrium: feeling unsteady on your feet without any spinning. Nerve changes in the feet, vision problems, joint issues and some medications can all play a part.

Being able to say which of these you feel, and when, is one of the most useful things you can bring to an appointment.

The most common causes of vertigo

BPPV: loose crystals in the inner ear

Benign paroxysmal positional vertigo, or BPPV, is the most common cause of vertigo. Your inner ear holds tiny calcium crystals that help it sense gravity. When some of them break loose and drift into one of the fluid-filled canals that sense rotation, certain head movements send your brain a false “spinning” signal.

The pattern is distinctive:

• It is triggered by changing head position: rolling over in bed, lying down, sitting up, looking up or bending over.
• The spinning is intense but short, usually less than a minute.
• Nausea is common; hearing is normally unaffected.

BPPV becomes more common with age and sometimes follows a bump to the head, though often there is no clear reason. A doctor can usually confirm it with a simple positional test in the office and treat it with repositioning maneuvers, a sequence of guided head and body positions that move the crystals back where they belong. Many people feel better quickly, although BPPV can come back.

Vestibular neuritis and labyrinthitis

These happen when the inner ear or its balance nerve becomes inflamed, often after a viral illness such as a cold. The vertigo comes on suddenly, can be severe and constant for a day or more, and often brings nausea and vomiting. It then eases gradually over days to weeks. Labyrinthitis also affects hearing, with hearing loss or ringing in the ear.

Ménière’s disease

Ménière’s disease causes episodes of vertigo that last from about 20 minutes to several hours, along with fluctuating hearing loss, ringing (tinnitus) and a feeling of fullness or pressure in one ear. It is linked to a fluid imbalance in the inner ear and is usually managed over the long term.

Vestibular migraine

Migraine does not always mean a headache. In vestibular migraine, episodes of vertigo or motion sensitivity can happen with or without head pain, often alongside sensitivity to light or sound.

Other contributors

Ear infections, some medications (including certain blood pressure medicines and sleep aids), and dehydration, which is easy to slip into during a South Florida summer, can all cause or worsen dizziness. Less commonly, vertigo is a sign of a stroke or another problem in the brain, which is why new or unusual symptoms deserve a proper look.

When vertigo is an emergency

Most vertigo is not dangerous, but a stroke can cause sudden dizziness too. Call 911 right away if vertigo comes with any of these:

• Slurred speech or trouble understanding words
• A drooping face, or weakness or numbness on one side of the body
• Double vision or sudden loss of vision
• A sudden, severe headache unlike any you have had
• Being unable to walk or stand
• Fainting, chest pain, shortness of breath, or a racing or irregular heartbeat

Stroke treatment works best when it starts fast, so do not wait to see if it passes and do not drive yourself. If lightheadedness comes with palpitations, our guide to AFib symptoms and irregular heartbeat explains what to watch for.

How a doctor works out the cause

Diagnosing vertigo is mostly careful detective work. Expect questions about exactly what it feels like, how long each episode lasts, what sets it off, whether your hearing has changed, and every medication you take. The exam often includes watching your eye movements, checking balance and coordination, a quick neurological check, positional testing and blood pressure lying down and standing up.

Many people need no tests at all. When they are needed, they may include a hearing test, blood work, an EKG or heart monitoring for lightheadedness, or imaging such as an MRI if a brain cause needs to be ruled out.

The usual way vs. with your own doctor

• Waking up spinning on a Saturday. The usual way: a long emergency room wait, then a referral weeks out. With your own doctor: you text a physician who knows your history and medications, talks through the red flags with you, and sees you the same or next day.
• Woozy after starting a new medication. The usual way: wait for your next appointment or guess on your own. With your own doctor: a quick call, a review of your up-to-date medication list, a blood pressure check in the office and an EKG in the same building if needed.
• Episodes that keep returning. The usual way: separate trips across town for imaging and a specialist. With your own doctor: MRI on site with results reviewed with you, and a specialist visit usually arranged the same day, with your records sent ahead.

Treatment and recovery

Treatment depends on the cause, which is why getting the diagnosis right matters:

1. Repositioning maneuvers for BPPV, done in the office, sometimes with a home version you are taught to repeat.
2. Vestibular rehabilitation, a type of physical therapy with exercises that help your brain recalibrate your balance. It is especially helpful after vestibular neuritis or when unsteadiness lingers.
3. Short-term medicines to calm severe nausea or spinning during an acute attack. These are generally not meant for long-term use.
4. Treating what is behind it, such as adjusting medications, improving hydration, or managing migraine or Ménière’s disease.

Staying safe while you are dizzy

Vertigo raises the risk of falling, and falls can be serious, especially for older adults. A few simple habits help:

• Sit on the edge of the bed for a moment before standing up.
• Use nightlights and clear loose rugs and clutter from walkways.
• Hold handrails on stairs, and skip ladders and driving during an episode.
• Drink water through the day, especially outdoors in the heat.
• Keep a short log: when it happened, how long it lasted and what you were doing.
