Vertigo (Dizziness): What It Is, Symptoms, Causes, Diagnosis, and Treatment
Request Call Back
Overview
Vertigo is a specific type of dizziness—the false sensation that you or your surroundings are spinning or moving when nothing is actually in motion. It arises when the body’s balance network (the vestibular system in the inner ear, the eyes, and the brain) sends conflicting signals to the brain. Clinically, dizziness can feel like light-headedness, faintness, imbalance, or spinning; vertigo refers to the spinning/rotational illusion and is the most common dizziness subtype seen in emergency and outpatient care.
At MedicalPoint Hospital, ENT (Otolaryngology), Neurology, and Audiology teams work together to identify whether vertigo is peripheral (inner-ear origin) or central (brainstem/cerebellum origin) and to deliver targeted, guideline-based treatment.
Quick facts: how vertigo differs from “general dizziness”
- Vertigo: a spinning or tilting sensation, often positional and abrupt.
- Presyncope/faintness: feeling you might pass out, commonly cardiovascular.
- Disequilibrium/imbalance: unsteady gait without spin.
- Non-specific light-headedness: often related to anxiety, medications, or metabolic issues.
Understanding which sensation you have speeds diagnosis and avoids unnecessary tests.
What causes vertigo?
Peripheral vertigo (inner-ear/vestibular causes)
These account for most vertigo presentations and typically produce intense spinning, nystagmus (involuntary eye movements), nausea, and vomiting. Hearing symptoms (fullness, tinnitus, hearing loss) may coexist.
- Benign Paroxysmal Positional Vertigo (BPPV): Brief (seconds to <1 min) spinning triggered by head position changes (turning in bed, looking up). Caused by displaced otoconia crystals in the semicircular canals.
- Vestibular neuritis (acute unilateral vestibulopathy): Sudden, severe vertigo lasting hours–days, often after a viral illness; hearing is typically normal.
- Labyrinthitis: Similar to vestibular neuritis but with hearing loss or tinnitus due to inner-ear inflammation.
- Ménière’s disease: Recurrent attacks (20 min–12 hours) of vertigo with fluctuating hearing loss, tinnitus, and aural fullness, related to inner-ear fluid (endolymphatic) dysregulation.
- Perilymphatic fistula or superior canal dehiscence: Vertigo worsened by pressure/straining or loud sound.
- Ototoxicity: Certain drugs (e.g., aminoglycosides) can damage vestibular hair cells.
- Post-traumatic vestibulopathy: After head/neck injury.
Central vertigo (brain/brainstem causes)
Symptoms may be milder in spin quality but accompanied by neurologic signs. Central causes require urgent evaluation.
- Stroke or transient ischemic attack in the brainstem/cerebellum
- Multiple sclerosis and other demyelinating disease
- Migraine with brainstem aura/vestibular migraine
- Tumors, hemorrhage, or structural lesions of posterior fossa
Red flags for central vertigo: new neurologic deficits (double vision, slurred speech, facial or limb weakness/numbness), severe headache, ataxia/cannot walk, vertical nystagmus, persistent vertigo not modified by position, or significant vascular risk factors. Seek emergency care.
Vertigo symptoms and associated features
- Spinning/rotational sensation (you or the room)
- Nausea, vomiting, pallor, cold sweats
- Nystagmus visible to a clinician (direction helps localize)
- Imbalance or ataxia (unsteady gait)
- Triggers: rolling in bed, looking up, sudden head turns (typical of BPPV)
- Ear symptoms (fullness, tinnitus, hearing fluctuation) suggest inner-ear disease
- Visual blurring, oscillopsia (environment bouncing) during head movement
How is vertigo diagnosed?
History and examination (EEAT-aligned, guideline based)
A clinician distinguishes timing, triggers, and targeted exam:
- Timing: single prolonged episode (hours–days), recurrent spontaneous attacks, or brief positional spells.
- Triggers: head position, sound/pressure, exertion, anxiety, medications, recent infections.
- Focused exam: ear exam; Dix–Hallpike or supine roll test for BPPV; observation of nystagmus; gait assessment; HINTS bedside oculomotor exam (Head-Impulse, Nystagmus, Test of Skew) in continuous vertigo to differentiate peripheral neuritis from central stroke (performed by trained clinicians).
- Vital signs: orthostatic blood pressure/heart rate when presyncope suspected.
Tests (ordered as indicated)
- Audiometry (hearing test) for suspected Ménière’s or labyrinthitis.
- Video nystagmography (VNG)/video head impulse test (vHIT) for vestibular function.
- MRI brain/internal auditory canals when central cause suspected, hearing asymmetry, or atypical course.
- Laboratory tests only when clinically directed (infection, autoimmune, thyroid, B12, glucose).
- ECG/Holter if cardiac presyncope considered.
At MedicalPoint Hospital, we offer same-day Dix–Hallpike testing and canalith repositioning, onsite audiology, and rapid-access MRI when red flags are present.
Evidence-based treatment options
1) Canalith repositioning maneuvers (first-line for BPPV)
- Epley (posterior canal), Barbecue roll (horizontal canal), or Semont maneuvers move displaced crystals back into the utricle. Relief is often immediate or within days. Home exercises may reinforce results.
- Short-term vestibular suppressants (see below) may reduce nausea but should not delay maneuvers.
2) Medications (short courses, symptom-directed)
Used to reduce acute vertigo, nausea, and anxiety—particularly in vestibular neuritis/labyrinthitis—but prolonged use can slow central compensation.
- Antihistamines (e.g., meclizine, dimenhydrinate)
- Antiemetics (ondansetron, metoclopramide—use per clinician advice)
- Benzodiazepines (short term for severe episodes; avoid long-term)
- Corticosteroids may be considered early in vestibular neuritis in selected patients after risk–benefit review.
- Ménière’s disease: Salt restriction, diuretics; individualized plans may include intratympanic therapies when refractory—managed by ENT.
3) Vestibular rehabilitation therapy (VRT)
Customized exercises by a vestibular physiotherapist to retrain the brain’s balance strategies: gaze stabilization, habituation, and balance training. VRT improves recovery after neuritis, chronic vestibulopathy, and persistent postural-perceptual dizziness (PPPD).
4) Treat the underlying cause
- Migraine-related vertigo: trigger management, sleep regularity, and standard migraine preventives.
- Perilymph fistula/canal dehiscence: activity modification, sometimes surgery.
- Infections or autoimmune inner-ear disease: targeted otolaryngology care.
- Central causes (e.g., stroke, MS): urgent neurologic pathways and disease-specific therapy.
5) Lifestyle and self-care (adjuncts)
- Regular sleep, hydration, and meals; limit alcohol and caffeine excess.
- Avoid rapid head movements during acute phases; resume gradual mobilization to promote compensation.
- Manage anxiety with breathing techniques; consider brief psychological support if fear of attacks limits activity.
When should you seek urgent care?
- New severe, continuous vertigo with inability to walk, severe headache, double vision, slurred speech, facial droop, limb weakness/numbness, or loss of consciousness.
- Vertigo with acute hearing loss or one-sided ear fullness/ringing unresponsive to initial care.
- Head injury preceding dizziness.
These features can indicate stroke or other central pathology and require immediate evaluation.

FAQs
Is vertigo the same as low blood pressure dizziness?
No. Vertigo is a spinning illusion from vestibular dysfunction; presyncope from low blood pressure feels like faintness rather than rotation.
Will BPPV go away on its own?
Many episodes remit spontaneously over weeks, but canalith repositioning hastens recovery and reduces recurrences.
Do I need brain imaging for every episode?
Not typically. Imaging is reserved for red flags, abnormal neurologic exam, or atypical/refractory cases—your clinician will decide.
Key clinical terms you may hear
- Nystagmus: rhythmic eye movement that helps localize cause (peripheral vs central).
- HINTS exam: specialized bedside eye-movement series to distinguish neuritis from stroke in continuous vertigo (performed by trained clinicians).
- Otoconia: inner-ear calcium crystals that misplace in BPPV.
- Endolymphatic hydrops: inner-ear fluid imbalance associated with Ménière’s disease.
