Dizziness vs. Vertigo: Understanding the Differences
Manhattan Physical Therapy
Feeling dizzy can be unsettling, especially when you are unsure whether you are experiencing ordinary lightheadedness or something more specific, such as vertigo. Although people often use the two terms interchangeably, they do not describe exactly the same sensation.
Dizziness is a broad term for an altered sense of balance, orientation, or steadiness. Vertigo is a specific type of dizziness that creates the sensation that you or your surroundings are moving, usually spinning.
The distinction matters because dizziness and vertigo can have very different causes. Dehydration, a sudden change in blood pressure, medication effects, migraine, and problems involving the inner ear can all contribute to dizziness. Vertigo, meanwhile, is commonly associated with disorders of the vestibular system, including benign paroxysmal positional vertigo (BPPV), although neurological and other medical conditions can also cause it.
These symptoms are also common. A nationally representative U.S. survey found that 14.8% of adults, equivalent to about 33.4 million people, reported dizziness or balance problems within a 12-month period. Interestingly, 61.1% of those individuals reported more than one type of dizziness symptom, showing why describing the sensation precisely can be more useful than simply saying, "I feel dizzy."
What Is Dizziness?
Dizziness is not a single condition. It is an umbrella term that people use to describe several different sensations, including feeling lightheaded, woozy, weak, unsteady, disoriented, or as though they may lose their balance.
For example, someone may feel dizzy after standing up quickly, becoming dehydrated, skipping a meal, taking certain medications, or experiencing a change in blood pressure. Others may describe a vague feeling that they are not quite steady when walking or standing.
Dizziness can also occur without any spinning sensation. You may feel as though you are floating, swaying, rocking, or walking on an unstable surface. In some cases, the problem is related to how the brain combines information from the inner ears, eyes, muscles, joints, and nervous system to maintain balance.
This is one reason the word "dizziness" alone does not tell a healthcare professional what is causing the problem. The timing of symptoms, activities that bring them on, accompanying symptoms, and your medical history all help narrow down the possible cause. A useful starting point is to ask yourself:
Do I feel like I might faint or pass out?
Do I feel unsteady when standing or walking?
Does the sensation happen when I move my head or change position?
Does the room actually seem to spin or move?
Do I also have nausea, headache, hearing changes, ringing in the ears, or difficulty walking?
How long does each episode last?
What Is Vertigo?
Vertigo is a specific sensation of movement. Instead of simply feeling lightheaded or unsteady, you may feel as though you are spinning, the room is rotating, the floor is moving, or your body is being pulled in a particular direction.
Vertigo can occur when you are completely still. For some people, an episode lasts only seconds. For others, symptoms may continue for minutes, hours, or longer, depending on the underlying condition.
One of the most common causes is benign paroxysmal positional vertigo (BPPV). BPPV occurs when tiny calcium carbonate crystals in the inner ear become displaced and enter a semicircular canal, interfering with the system that detects head movement. This can produce brief but intense vertigo when you roll over in bed, sit up, bend forward, look upward, or make another particular head movement.
Vertigo can also be classified broadly as peripheral or central. Peripheral vertigo is associated with the inner ear or vestibular nerve and includes conditions such as BPPV, vestibular neuritis, labyrinthitis, and Ménière's disease. Central vertigo is associated with problems affecting the brain, including certain strokes, traumatic brain injuries, and infections.
Importantly, experiencing vertigo does not automatically mean that you have an inner-ear disorder. Some migraines and neurological conditions can produce vertigo-like symptoms, which is why recurrent or unexplained episodes deserve appropriate evaluation.
Dizziness vs. Vertigo: What Is the Difference?
| Dizziness | Vertigo |
|---|---|
| Broad symptom category | Specific type of dizziness |
| May feel lightheaded, woozy, weak, or unsteady | Usually feels like you or your surroundings are moving |
| May occur after standing up, dehydration, medication effects, or other triggers | Often associated with vestibular disorders, although other causes are possible |
| Does not require a spinning sensation | Spinning or another false sense of movement is characteristic |
| Can have cardiovascular, metabolic, neurological, visual, medication-related, or vestibular causes | Frequently involves the vestibular system, particularly the inner ear |
What Causes Dizziness and Vertigo?
There is no single cause of dizziness or vertigo. The balance system depends on information from the inner ear, eyes, muscles, joints, and brain. If one part of that system is disrupted, you may experience dizziness, vertigo, imbalance, or a combination of symptoms.
Common causes of dizziness
Possible causes include:
Dehydration, particularly after illness, exercise, or inadequate fluid intake
Changes in blood pressure, including feeling lightheaded after standing
Low blood sugar
Anemia
Medication side effects
Motion sickness
Concussion or head injury
Anxiety and stress
Inner-ear disorders
Problems affecting vision or sensory information
Neurological conditions
Common causes of vertigo
Vertigo is often associated with the vestibular system. Common examples include:
BPPV: The most common form of positional vertigo. Episodes are typically brief and triggered by specific changes in head position, such as rolling over in bed or looking upward.
Vestibular migraine: This can cause vertigo, rocking or swaying, imbalance, and other forms of dizziness. Episodes may last from minutes to hours and, in some people, up to several days. Sensitivity to light or sound and migraine symptoms may occur with or without a typical headache.
Ménière's disease: This inner-ear disorder can cause recurrent attacks of vertigo along with fluctuating hearing loss, ear fullness, tinnitus, nausea, or vomiting. The source material describes attacks lasting approximately 20 minutes to 12 hours.
Vestibular neuritis or labyrinthitis: Inflammation affecting structures involved in balance can cause significant vertigo and difficulty maintaining stability.
Neurological causes: Conditions affecting the brain can also produce vertigo. Central causes are less common than peripheral vestibular causes but can be medically serious, particularly when symptoms begin suddenly or occur with neurological changes.
One important point is that treating the underlying cause is usually more useful than simply trying to suppress the sensation. For example, research supports canalith repositioning maneuvers for appropriately diagnosed BPPV. A systematic review of randomized and quasi-randomized trials found substantially higher odds of symptom and positional-test resolution with canalith repositioning than with control treatment.
Even after successful treatment, some people continue to experience imbalance or residual dizziness. A meta-analysis involving 4,487 people across 31 studies found residual dizziness in about 43% of patients after successful BPPV repositioning. This is one reason persistent unsteadiness should not automatically be interpreted as evidence that the original treatment failed.
How Are Dizziness and Vertigo Diagnosed?
Because dizziness and vertigo can have many possible causes, diagnosis usually starts with a detailed discussion of your symptoms rather than immediately ordering scans or other tests. A healthcare professional may ask:
When did the symptoms begin?
How long does each episode last?
Does the sensation occur constantly or in separate episodes?
Does turning your head, rolling over in bed, standing up, walking, or looking upward trigger it?
Do you feel spinning, lightheadedness, rocking, or general unsteadiness?
Do you have nausea or vomiting?
Have you noticed hearing loss, ear pressure, or ringing in your ears?
Do you have headaches, sensitivity to light, or a history of migraine?
Have you recently had a head injury, illness, or change in medication?
The answers can provide important clues. For example, brief episodes of spinning brought on by rolling over in bed may point toward BPPV, while persistent imbalance after a vestibular disorder may require a different type of evaluation.
A physical examination may include balance testing, eye-movement observation, walking assessment, and positional tests. For suspected posterior-canal BPPV, the Dix-Hallpike maneuver is commonly used. If the history suggests BPPV but the Dix-Hallpike test does not show the expected findings, a supine roll test may be used to evaluate the lateral semicircular canal. The American Academy of Otolaryngology-Head and Neck Surgery guideline recommends these positional tests as part of appropriate BPPV diagnosis.
When Should You Seek Medical Attention for Dizziness or Vertigo?
An occasional brief episode of dizziness does not necessarily indicate a serious problem. However, new, severe, recurrent, or unexplained dizziness should not simply be ignored, particularly when it interferes with walking, driving, work, or everyday activities. Seek prompt medical evaluation if dizziness or vertigo is accompanied by symptoms such as:
Sudden weakness or numbness
Difficulty speaking or understanding speech
New double vision or significant vision changes
Severe difficulty walking or inability to stand
Fainting or loss of consciousness
A sudden, severe headache
New hearing loss
Chest pain or significant heart palpitations
Persistent vomiting
Symptoms following a significant head injury
If your symptoms are recurrent but not an emergency, keeping a symptom diary can be surprisingly useful. Write down what you were doing, your body or head position, how long the episode lasted, what the sensation felt like, and any other symptoms you noticed. This information can help your healthcare provider identify patterns that may otherwise be difficult to remember.
Can Dizziness or Vertigo Be Prevented?
Not every episode of dizziness or vertigo can be prevented. Some conditions occur without an obvious trigger. Still, several practical habits can reduce avoidable contributors to dizziness and help you stay safer if balance symptoms occur.
Stay adequately hydrated, eat regular balanced meals, remain physically active when it is safe to do so, manage stress, and review medications with your healthcare provider if you notice dizziness after starting or changing a medication.
If you already have balance problems, make your surroundings safer. Remove loose rugs and other tripping hazards, keep frequently used items within easy reach, use adequate lighting, and be especially careful when getting out of bed or standing after sitting for a long time.
For people who have had BPPV, recurrence is also possible. This is why follow-up matters even after symptoms improve. The clinical practice guideline recommends reassessment after an initial period of treatment or observation and further evaluation when symptoms persist.
Dizziness vs. Vertigo: When Should You Consider Physical Therapy?
If dizziness or vertigo is making it harder to walk, exercise, turn your head, get out of bed, work, or participate in activities you normally enjoy, a vestibular physical therapy evaluation may be worth considering.
Physical therapy is particularly relevant when symptoms are associated with a diagnosed vestibular problem, balance impairment, difficulty with gaze stability, or reduced confidence with movement. It can also be useful when symptoms persist after the initial medical treatment of a vestibular disorder.
The important first step is determining why you are dizzy. Physical therapy is not intended to replace medical evaluation, particularly when symptoms are new, severe, unexplained, or accompanied by warning signs.
Don’t let dizziness or vertigo keep you from moving comfortably and confidently. A personalized vestibular physical therapy evaluation can help identify your balance and movement limitations and guide an appropriate treatment plan.
