TL;DR
Dizziness is a broad term for feeling faint, woozy, weak, or wobbly, while vertigo specifically means a spinning sensation. It is one of the most common reasons adults see a doctor, but it rarely points to a life-threatening condition. The most common cause of vertigo is BPPV, triggered by quick head movements, but dizziness can also stem from inner ear problems, blood pressure changes, medicines, anxiety, anemia, low blood sugar, or dehydration. Most dizziness improves on its own within a few weeks, and when treatment is needed, it ranges from a simple head-positioning maneuver to medicines, balance exercises, and home safety steps.
Quick Answer
What is dizziness? A term for sensations like feeling faint, woozy, weak, or wobbly; the spinning sensation is more precisely called vertigo.
Is dizziness dangerous? Rarely. It is one of the more common reasons adults see a doctor, and dizziness alone is usually not life-threatening, though new severe spells with chest pain, slurred speech, or weakness need emergency care.
What causes it most often? Benign paroxysmal positional vertigo (BPPV), a brief spinning sensation triggered by rapid head movement, is the most common cause of vertigo.
How is it treated? Most dizziness improves without treatment within a few weeks. When needed, treatment includes canalith repositioning (the Epley maneuver) for BPPV, medicines for related symptoms, and vestibular rehabilitation exercises.
What can I do at home? Sit or lie down when dizzy, avoid sudden movements, fall-proof your home, stay hydrated, and limit caffeine, alcohol, salt, and tobacco.
What is dizziness (and what is vertigo)?
Dizziness is a term people use to describe a range of sensations, such as feeling faint, woozy, weak, or wobbly. The sense that you or your surroundings are spinning or moving is more precisely termed vertigo.
Dizziness is one of the more common reasons adults see a healthcare professional. Frequent dizzy spells or constant dizziness can seriously affect your life. But dizziness rarely means that you have a life-threatening condition.
Treatment depends on the cause and your symptoms. Treatment often helps, but the symptoms may come back.
Dizziness symptoms: what to watch for
People who have bouts of dizziness may describe a sense of motion or spinning (vertigo), lightheadedness or feeling faint, a loss of balance or unsteadiness, or a feeling of floating, wooziness, or heavy-headedness.
These feelings may be triggered or made worse by walking, standing up, or moving your head. Dizziness may come along with an upset stomach, or it may be so sudden or severe that you need to sit or lie down. A bout may last seconds or days, and it may come back.
Dizziness vs. vertigo: the difference at a glance
Vertigo — What it feels like: The room is spinning, or you are spinning in the room; Common cause family: Inner ear conditions such as BPPV, vestibular neuritis, Meniere's disease
Lightheadedness — What it feels like: Feeling faint, like you might pass out; Common cause family: Circulation problems such as a blood pressure drop
Loss of balance — What it feels like: Unsteady on your feet, trouble staying upright; Common cause family: Nervous system conditions, inner ear problems, medicines
Wooziness — What it feels like: Floaty, heavy-headed, or off-kilter; Common cause family: Anxiety, overheating, dehydration
How your balance system works
Your sense of balance depends on combined input from three parts of your sensory system. Your eyes tell you where your body is in space and how it is moving. Your sensory nerves send messages to your brain about body movements and positions. Your inner ear houses sensors that detect gravity and back-and-forth motion.
Loop-shaped canals in the inner ear contain fluid and fine, hairlike sensors that help keep balance. At the base of the canals are the utricle and saccule, each with a patch of sensory hair cells containing tiny particles called otoconia. These monitor the position of your head in relation to gravity and linear motion, such as going up in an elevator or moving in a car.
With inner ear conditions, your brain receives signals from the inner ear that do not match what your eyes and sensory nerves report. Vertigo is what results as your brain works to sort out the confusion.
What causes dizziness?
The way dizziness feels, what triggers it, how long it lasts, and your other symptoms all give healthcare professionals clues about the cause. The list below organizes the main cause families from the source material.
Inner ear conditions — What happens: Signals conflict between ear, eyes, and nerves; Typical clues: Spinning after head movement; ear fullness, ringing, or hearing changes
Circulation problems — What happens: Too little blood reaches the brain; Typical clues: Feeling faint after standing up quickly; heart symptoms
Medicines — What happens: Side effect of certain drugs; Typical clues: Starts after a new medicine or dose change
Anxiety disorders — What happens: Lightheaded or woozy feeling; Typical clues: During panic attacks or fear of open spaces
Blood and metabolic — What happens: Anemia or low blood sugar; Typical clues: Fatigue and pale skin; sweating with diabetes
Environment — What happens: Overheating or dehydration; Typical clues: After heat exposure or not drinking enough fluids
Inner ear conditions that cause vertigo
Benign paroxysmal positional vertigo (BPPV) causes an intense and brief sense of spinning or moving, triggered by a rapid change in head movement, such as turning over in bed, sitting up, or getting hit in the head. BPPV is the most common cause of vertigo.
A viral infection called vestibular neuritis can cause intense, constant vertigo. It is an infection of the vestibular nerve, the main nerve leading from the inner ear to the brain. If you also have sudden hearing loss, the condition is called labyrinthitis, which affects the nerve controlling balance and hearing.
Migraine can bring bouts of vertigo or other dizziness even when you are not having bad headaches. Such bouts can last minutes to hours and may come with headache and sensitivity to light and noise.
Meniere's disease is a rare condition involving too much fluid in the inner ear. It causes sudden vertigo bouts that can last for hours, along with hearing loss that comes and goes, ringing in the ear, and a plugged-ear feeling.
Circulation problems that cause dizziness
You may feel dizzy, faint, or off balance if too little blood reaches your brain. A form of low blood pressure called orthostatic hypotension may make you briefly feel faint or dizzy after sitting up or standing too quickly.
Poor blood flow from conditions such as cardiomyopathy, heart attack, irregular heartbeat, or transient ischemic attack can also cause dizziness. A drop in the total blood flowing through the body may leave the brain or inner ear short of blood.
Other causes of dizziness
Conditions affecting the brain, spinal cord, or nerves can cause balance loss that worsens over time. These include Parkinson's disease and multiple sclerosis.
Medicines are another common cause. Anti-seizure medicines, antidepressants, sedatives, and tranquilizers can all cause dizziness. Medicines that lower blood pressure may cause faintness if they lower it too much.
Anxiety disorders such as panic attacks and agoraphobia, a fear of leaving home or being in large open spaces, may cause lightheadedness or a woozy feeling. Anemia (too few healthy red blood cells) can bring dizziness along with fatigue, weakness, and pale skin.
Low blood sugar, or hypoglycemia, usually affects people with diabetes who use insulin, with dizziness alongside sweating and anxiety. Note that feeling unwell after a missed meal is not considered hypoglycemia.
Two environmental causes deserve attention. Carbon monoxide poisoning often feels flu-like, with headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. Overheating or dehydration, from hot-weather activity or not drinking enough fluids, can make you dizzy, with higher risk if you take certain heart medicines.
Who is most at risk?
Two factors stand out. Older adults are more likely to have health conditions that cause dizziness, especially reduced balance, and they are also more likely to take medicines that cause dizziness. And a past bout of dizziness makes you more likely to get dizzy again in the future.
Possible complications
Dizziness can raise your risk of falling and hurting yourself. Getting dizzy while driving a car or running heavy machinery makes an accident more likely. You may also face long-term complications if the health condition causing your dizziness goes untreated.
When to see a doctor
See your healthcare professional for any repeated, sudden, severe, or long-lasting dizziness or vertigo with no clear cause.
Get emergency medical care if new, severe dizziness or vertigo comes with any of the following:
Pain: Sudden, severe headache or chest pain
Heart: Rapid or irregular heartbeat
Weakness: Loss of feeling or movement in arms or legs, stumbling, trouble walking, or facial weakness
Breathing: Trouble breathing
Consciousness: Fainting or seizures
Eyes or ears: Double vision or a sudden change in hearing
Brain: Confusion or slurred speech
Stomach: Ongoing vomiting
How dizziness is diagnosed
Diagnosis involves finding the cause of your dizziness or vertigo. Your healthcare professional asks about your symptoms and the medicines you take, then performs a physical exam. During this exam, they check how you walk, how you keep your balance, and whether the major nerves of your central nervous system are working.
If a stroke is suspected, or if you are older or had a blow to the head, you may need imaging tests such as an MRI or CT scan right away. A hearing test and balance tests may also be part of the workup.
Eye movement testing: How your eyes track a moving object; an eye motion test using water or air placed in the ear canal
Head movement testing (Dix-Hallpike maneuver): Whether your vertigo is caused by BPPV; a simple head movement test that can confirm it
Posturography: Which parts of your balance system you rely on most and which are failing; you stand barefoot on a platform and keep balance under various conditions
Rotary chair testing: Inner ear balance function using a computer-controlled chair moving slowly in a circle, or back and forth in a small arc at faster speeds
Blood and heart tests: Infection, and heart and blood vessel health
Treatment options
Dizziness often gets better without treatment. The body usually adapts to whatever is causing the condition within a few weeks. If you seek treatment, it is based on the cause and your symptoms, and may include medicines and balance exercises.
Head-positioning movements for BPPV
A technique called canalith repositioning, or the Epley maneuver, involves a series of head movements. It usually helps BPPV improve more quickly than simply waiting, and can be done by your healthcare professional, an audiologist, or a physical therapist. It often works after one or two treatments.
Before this procedure, tell your healthcare professional if you have a neck or back condition, a detached retina, or a condition affecting blood vessels.
Balance therapy
You may learn exercises to make your balance system less sensitive to motion. This physical therapy technique, called vestibular rehabilitation, is used for people with dizziness from inner ear conditions such as vestibular neuritis.
Talk therapy
Talking with a psychologist, psychiatrist, or other mental healthcare professional may help people whose dizziness is caused by anxiety.
Medicines
Several medicine groups play a role depending on the cause. Water pills (diuretics), along with a low-salt diet, may reduce vertigo bouts in Meniere's disease. Antihistamines and anticholinergics provide fast relief from vertigo, dizziness, and upset stomach, though many cause drowsiness. Anti-anxiety medications such as diazepam and alprazolam can help but carry risks of drowsiness and addiction. Preventive medicines can reduce migraine attacks for those with migraine-related vertigo.
Surgery or procedures (rare)
In rare, stubborn cases, a doctor may inject the affected inner ear with the antibiotic gentamicin, which stops that ear's balance function so the healthy ear takes over. Very rarely, a surgeon may remove the inner ear sense organ (labyrinthectomy), which causes complete hearing loss in that ear and is reserved for people with serious hearing loss whose dizziness persists after other treatments.
Home care and preventing falls
If you tend to have repeated bouts of dizziness, several practical steps help. Be aware of your fall risk: walk with a cane if needed, and avoid fast or sudden movements. Fall-proof your home by removing tripping hazards such as area rugs and exposed cords, using nonslip mats in the bath and shower, and keeping good lighting.
Sit or lie down right away when you feel dizzy. For a major vertigo bout, lie still with your eyes closed in a darkened room. Do not drive or run heavy machinery if you often become dizzy without warning.
Limit caffeine, alcohol, salt, and tobacco, since too much can worsen symptoms. Drink enough fluids, eat a healthy diet, get enough sleep, and manage stress.
If your dizziness comes with an upset stomach, an over-the-counter antihistamine such as meclizine or dimenhydrinate may help, though it can make you sleepy. If a medicine is causing your dizziness, talk with your healthcare professional about lowering the dose or safely stopping it. If overheating or dehydration is the cause, rest in a cool place and drink water or a sports drink.
Preparing for your appointment
Your main healthcare professional can usually find and treat the cause of your dizziness. You may be referred to an otolaryngologist (ear, nose, and throat doctor) or a neurologist (a doctor who treats brain and nervous system conditions).
Before your appointment, take a family member or friend along if you can, since someone with you can help you remember the information you receive. Check whether you need any restrictions beforehand; if vestibular testing is planned, your team gives instructions about medicines to avoid the night before and what to eat on the day of testing.
Be prepared to describe your dizziness in specific terms, since your description is key to finding the cause. Note whether the room seems to spin or whether you feel like you are spinning in the room, whether you feel like you might pass out, how long bouts last, what triggers them, and whether they come with ringing or fullness in your ears, hearing trouble, or blurred vision.
List your other health conditions, all medicines, vitamins, and supplements, and bring questions. Useful questions include the most likely cause, what tests are recommended, whether the problem is short term or long lasting, what treatment options might help, whether it is safe to drive, and whether you should see a specialist.
In the meantime, take your time changing posture if you feel lightheaded when you stand up. And if you have had dizzy bouts while driving, have someone else drive you in the weeks before your checkup.
Bottom line
Dizziness is a symptom, not a diagnosis. It describes many different sensations, and the spinning kind has its own name, vertigo. Because it can come from the inner ear, circulation, medicines, anxiety, or metabolism, the way it feels and what triggers it matters as much as the feeling itself.
Most cases are not serious, and BPPV, the most common cause of vertigo, often responds quickly to a simple head-positioning procedure. Even when a clear cause is never found, medicines, exercises, and practical home steps can make the symptoms easier to live with.
Your next step: If you have repeated, sudden, severe, or long-lasting dizziness with no clear cause, see your healthcare professional. Describe your symptoms precisely, bring your full medicine list, and ask what tests fit your case. And never ignore a dizzy spell that comes with chest pain, weakness, slurred speech, or fainting, as those need emergency care right away.
