Vertigo vs. Dizziness: What Is the Difference?

What exactly does vertigo feel like?

People with vertigo describe a clear rotational sensation — as if the room is spinning around them, or they are spinning inside a still room. It may last seconds to minutes, or it may be more persistent. It often comes with nausea, a tendency to veer to one side, or involuntary eye movements called nystagmus.

Vertigo is not a diagnosis; it is a symptom. The clinically relevant question is whether its origin is peripheral (inner ear) or central (brainstem or cerebellum). Central vertigo is less common but more serious.

What does general dizziness feel like, and how is it different?

Dizziness without spinning is usually described as:

• Lightheadedness — a feeling of nearly fainting or “graying out,” often from low blood pressure, dehydration, or standing up quickly
• Unsteadiness or imbalance — a sense of being off-kilter without the room rotating
• Wooziness or fogginess — a vague sense that something is off, without a clear spatial component

These sensations are more likely to reflect cardiovascular, metabolic, or medication-related causes than an inner ear problem.

What are the most common causes of vertigo?

Benign paroxysmal positional vertigo (BPPV) is the most common cause of true vertigo. It happens when small calcium carbonate crystals (otoliths) in the inner ear shift into the wrong semicircular canal. Brief, intense spinning triggered by rolling over in bed, looking up, or tilting the head is a classic pattern. A clinician can often diagnose and treat BPPV in the office using the Epley canalith repositioning maneuver, which has strong evidence for rapid resolution 1Ref 1Bhattacharyya N, Gubbels SP, Schwartz SR, Edlow JA, El-Kashlan H, Fife T, et al. (2017).Clinical Practice Guideline: Benign Paroxysmal Positional Vertigo (Update).BPPV clinical diagnosis and the Epley maneuver as treatment; criteria for imaging2Ref 2Hilton MP, Pinder DK (2014).The Epley (canalith repositioning) manoeuvre for benign paroxysmal positional vertigo.Evidence that the Epley maneuver resolves BPPV; faster resolution than watchful waiting.

Vestibular neuritis and labyrinthitis are inflammations of the vestibular nerve or inner ear that can cause prolonged vertigo lasting hours to days, often following a viral illness. The acute phase is managed with vestibular suppressants and anti-nausea medications. Vestibular rehabilitation — a structured program of balance and gaze-stability exercises — is well supported for the residual dizziness and imbalance that can follow and significantly outperforms no treatment 4Ref 4McDonnell MN, Hillier SL (2015).Vestibular rehabilitation for unilateral peripheral vestibular dysfunction.Moderate to strong evidence that vestibular rehabilitation is safe and effective for unilateral peripheral vestibular dysfunction; 39 RCTs, 2441 participants.

Ménière's disease involves episodic vertigo combined with hearing fluctuation, ringing in the ear (tinnitus), and a sensation of ear fullness. Episodes can last 20 minutes to several hours and recur unpredictably 3Ref 3Basura GJ, Adams ME, Monfared A, Schwartz SR, Antonelli PJ, Burkard R, et al. (2020).Clinical Practice Guideline: Ménière’s Disease.Ménière’s disease diagnostic features: episodic vertigo, hearing fluctuation, tinnitus, aural fullness.

Central causes — including cerebellar or brainstem strokes, tumors, or demyelinating disease — are less common but more serious. Vertigo that comes on suddenly with other neurological signs (double vision, facial numbness, severe imbalance, difficulty swallowing) needs prompt emergency evaluation.

What causes lightheadedness if it is not the inner ear?

Lightheadedness without spinning commonly traces back to:

• Orthostatic hypotension — blood pressure drops briefly when you stand, reducing blood flow to the brain momentarily
• Dehydration or heat — reduced blood volume produces a similar transient effect
• Anemia — low red cell count reduces oxygen delivery to the brain
• Low blood sugar — common in people with diabetes or those who have missed meals
• Medications — blood pressure drugs, diuretics, and some antidepressants are frequent culprits; reviewing your medication list is often productive
• Anxiety or panic — hyperventilation reduces carbon dioxide, causing head-swimming sensations that can mimic dizziness
• Cardiovascular arrhythmias — an irregular heartbeat can briefly reduce brain blood flow, producing faintness or near-syncope

How do clinicians tell the difference?

A clinician uses your description along with targeted tests to sort out the cause. Key questions: Does the room spin or just feel vague? Is it triggered by head position changes? How long does each episode last? Do you also have hearing changes or ear fullness?

Physical examination often includes the Dix-Hallpike test for BPPV, assessment of eye movements for nystagmus, a blood pressure check lying and standing, and neurological screening. Imaging (MRI of the brain) is reserved for cases with central red flags such as sudden onset with neurological symptoms, severe imbalance, or failure of typical vestibular patterns 1Ref 1Bhattacharyya N, Gubbels SP, Schwartz SR, Edlow JA, El-Kashlan H, Fife T, et al. (2017).Clinical Practice Guideline: Benign Paroxysmal Positional Vertigo (Update).BPPV clinical diagnosis and the Epley maneuver as treatment; criteria for imaging.

A Gale clinician can take a thorough history, perform relevant in-visit assessments, order initial bloodwork if a metabolic cause is suspected, and coordinate referrals if needed — including to ENT or neurology for persistent or diagnostically uncertain cases.
