14 Common Causes of Vertigo

2. Changes in Barometric Pressure

You may notice your dizziness or balance problems worsen when the weather changes. Shifts in barometric pressure can change the pressure inside your middle ear, which plays an important role in helping you stay balanced. Even small changes can create discomfort or a brief spinning sensation.

These pressure shifts often occur during flying, mountain driving, or scuba diving. When the outside air pressure rises or falls quickly, the air in your middle ear may not adjust right away. This mismatch can cause pressure, pain, or a popping feeling in your ears. For some people, it can trigger vertigo or make existing dizziness more noticeable.

In more pronounced cases, a significant pressure difference can lead to barotrauma, a condition where the ear cannot equalize pressure properly. You might feel ringing, fullness, or temporary hearing changes. These symptoms usually improve once the ears naturally equalize pressure, such as when you swallow or yawn.

3. Dehydration

When you lose more fluids than you take in, your body can’t work as it should. A drop in fluid levels reduces blood volume, lowering blood pressure and limiting oxygen flow to your brain. This imbalance can make you feel dizzy or as if the room is spinning.

Dehydration happens more easily than many people realize. Hot weather, exercise, fever, vomiting, or diarrhea can all drain your body’s water. Even mild dehydration may lead to lightheadedness, fatigue, or confusion that can trigger vertigo. You might also notice signs such as dry mouth, darker urine, or a faster heartbeat. These signals indicate your body needs more fluids.

Drinking water slowly and eating foods with high water content, like fruits or soups, can help your body recover. Certain medications, such as diuretics, raise the risk by increasing fluid loss. Older adults and people who sweat heavily are also more vulnerable to becoming dehydrated.

4. Stroke

A stroke happens when blood flow to part of your brain suddenly stops or decreases. This cuts off oxygen and nutrients, causing brain cells to die within minutes. When this affects the parts of the brain that control balance or coordination, you may experience vertigo.

You might notice sudden dizziness, loss of balance, or trouble standing without feeling that the room is spinning. Other symptoms like weakness or numbness on one side, trouble speaking, or vision changes can appear at the same time. These signs mean you need emergency medical care right away.

Vertigo can result from two types of stroke: ischemic, when a clot blocks a brain artery, and hemorrhagic, when a blood vessel ruptures and bleeds into the brain. Stroke-related vertigo often lasts longer or feels more intense than vertigo caused by inner-ear conditions. It may also come with nausea, vomiting, or unsteady walking.

5. Viral Meningitis

Viral meningitis can sometimes cause vertigo because it affects the tissues around your brain and spinal cord. When these tissues become swollen from infection, the inflammation can disrupt the brain areas that control balance. This may make you feel as though the room is spinning or you are moving when you are not.

This illness is often caused by common viruses such as enteroviruses, herpes viruses, influenza, and mumps. Anyone can develop viral meningitis, but babies, young children, and people with weakened immune systems face a higher risk. Although the viruses that lead to meningitis can spread between people, close contact with someone who has viral meningitis rarely causes meningitis itself.

You can lower your risk by washing your hands often, avoiding touching your face, limiting contact with people who are sick, and keeping vaccinations up to date. Vertigo linked to viral meningitis usually improves as the infection clears and the inflammation subsides.

6. Stress

Stress can affect your body in many ways, including how you sense balance. When you feel anxious or under pressure, your breathing and heart rate may change. This can reduce blood flow to the inner ear or brain, making you feel lightheaded or unsteady.

Your body’s stress response can also create tension in your neck and shoulder muscles. This tightness may interfere with balance signals sent from your body to your brain, sometimes leading to sensations of spinning or swaying that resemble vertigo.

Dizziness may become more frequent when stress occurs along with fatigue, dehydration, or skipping meals. These factors can lower blood pressure or glucose levels, making vertigo symptoms more noticeable.

Managing stress can help reduce these effects. Practice slow, steady breathing or take short breaks during the day to calm your nervous system. Regular sleep, physical activity, and balanced meals also support your body’s ability to regulate balance and prevent dizziness.

7. Acute Labyrinthitis

Acute labyrinthitis is an inner ear condition that happens when the labyrinth, a tiny structure deep inside your ear, becomes swollen or irritated. When this area is inflamed, the signals that control your balance get mixed up, leading to a spinning sensation or vertigo. The condition often develops after a viral infection such as a cold or flu.

Bacterial infections, allergies, or certain medications can also cause it. Symptoms usually appear suddenly and may include dizziness, nausea, vomiting, hearing loss, or ringing in one ear. Rest and medications such as antihistamines, sedatives, corticosteroids, or antivirals may be recommended.

Vestibular or balance therapy can help the brain adjust more quickly to changes in the inner ear. Most people start feeling better within a few weeks, but mild balance problems may linger for a short time. During recovery, avoid quick movements and bright lights, which can make symptoms worse.

8. Meniere’s Disease

Meniere’s disease affects your inner ear and can interfere with both hearing and balance. One of its hallmark signs is repeated episodes of vertigo that may last from minutes to several hours, often leaving you tired and unsteady afterward. You might experience ringing or buzzing in one ear, known as tinnitus, along with a sensation of pressure or fullness in the ear.

Hearing in the affected ear can fluctuate early on and may gradually worsen over time. Doctors believe Meniere’s disease happens when fluid builds up inside the inner ear. The exact cause is unclear, but factors like stress, infections, allergies, and poor drainage may contribute to this buildup.

Managing symptoms often includes a low-salt diet and resting during episodes. If vertigo strikes, lie still with your eyes closed until it passes. Avoid driving or using machinery until you feel fully steady, as symptoms can return unexpectedly.

9. Motion Sickness

Motion sickness happens when your brain receives mixed signals about movement from your eyes, inner ears, and body. If your eyes see one thing but your inner ears sense another, you may start to feel dizzy or sick. This often occurs when you read or look at a screen while traveling in a car, bus, plane, or boat.

Symptoms may include dizziness, nausea, sweating, paleness, headache, or sometimes vomiting. Children and women are more likely to get motion sickness than men. It can also happen more easily if you have a history of migraines or balance problems.

Sitting backward or looking at nearby objects while traveling can cause sensory confusion. Fast-moving scenes in virtual reality or on large screens can trigger symptoms because your eyes perceive motion while your body remains still. Motion sickness is not dangerous, but it can make travel uncomfortable.

10. Moving Into Certain Positions

Vertigo can begin when you move your head into specific positions, such as lying down, rolling over in bed, or looking up. These brief spinning episodes often last only a few seconds but may repeat many times a day.

This pattern is commonly linked to benign paroxysmal positional vertigo (BPPV), a condition that occurs when tiny crystals inside the inner ear shift out of place and disrupt the balance system. The unusual signals that result can make your brain perceive sudden spinning.

You may notice symptoms most when changing positions quickly, such as getting in or out of bed, bending down, or turning your head to one side. The spinning usually stops once you stay still, although mild nausea may continue for a short time.

BPPV is not dangerous, but repeated episodes can affect stability. In clinical settings, special repositioning maneuvers can guide the loose crystals back into place, often easing symptoms and helping restore balance.

11. Calcium Deposits in the Inner Ear

Sometimes vertigo happens when tiny calcium crystals called otoconia move into parts of your inner ear where they do not belong. These crystals normally rest in a small structure called the utricle. When they loosen and drift into a semicircular canal, they disrupt the fluid movement that helps your brain sense motion.

When your head changes position, the displaced crystals shift and send false signals to your brain. This creates the spinning sensation known as benign paroxysmal positional vertigo (BPPV). These brief episodes are often triggered by simple movements such as rolling in bed, bending down, or looking up.

Symptoms commonly include sudden dizziness, light-headedness, or loss of balance. Some people may also feel queasy or unsteady when standing or walking. BPPV becomes more likely with age as the crystals loosen naturally, and it can also happen after a head injury or long periods of lying still.

12. Vestibular Neuronitis

Vestibular neuronitis happens when the vestibular nerve, which sends balance and movement signals from your inner ear to your brain, becomes inflamed. This condition often begins suddenly and can cause intense spinning sensations that may last for several days. You may also feel off balance or unsteady when walking.

Most cases follow a viral infection such as a cold or flu. The inflammation disrupts the nerve’s ability to send accurate balance information, causing your brain to receive confusing signals from each ear. Unlike labyrinthitis, vestibular neuronitis does not usually cause hearing loss or ringing in the ear.

Symptoms often appear suddenly and may include constant vertigo lasting hours to days, nausea with occasional vomiting, difficulty walking in a straight line, and a strong spinning sensation that worsens with head movement. As the inflammation improves, your brain gradually adjusts to the uneven input from the inner ears.

13. Perilymph Fistula

A perilymph fistula occurs when a small tear or hole forms in the thin membranes that separate the middle ear from the inner ear. These membranes, called the oval and round windows, normally keep inner-ear fluid contained. When one of them is damaged, fluid leaks into the middle ear and interferes with both balance and hearing.

Symptoms often include vertigo that worsens with movement, coughing, sneezing, or lifting heavy objects. Changes in pressure, such as blowing your nose or flying in an airplane, may also make dizziness more pronounced. Some people notice mild hearing loss or a feeling of fullness in one ear.

This condition can develop after head injuries or barotrauma from diving or flying. Straining or sudden pressure changes may also trigger it, and in rare cases it can occur without a clear cause. Treatment includes rest, avoiding activities that increase pressure in your head, or, in some cases, surgically repairing the tear.

14. Brain Tumor

A brain tumor can cause vertigo when it presses on areas of the brain that control balance, such as the cerebellum or brainstem. This pressure affects the brain’s signal processing from the eyes and inner ears, causing a spinning or unsteady feeling.

Tumors can be noncancerous or cancerous. The symptoms depend on the tumor’s size and location. You might experience headache, nausea, vision changes, weakness on one side of your body, or trouble with coordination.

Some people develop dizziness or vertigo that worsens with movement or changes in position. When a tumor is located near the vestibular nerve or balance centers, vertigo is often a prominent symptom.

Doctors use imaging tests such as MRI or CT scans to locate the tumor. Treatment may involve surgery, radiation therapy, or drugs that fight cancer. These treatments reduce pressure, remove or shrink the tumor, and ease symptoms such as vertigo.
