Vertigo

Introduction

Vertigo is the false sensation that you or the world around you is spinning, tilting, or moving when nothing is actually moving. It can come on suddenly when you roll over in bed, last for minutes or hours during an attack, or linger as a background sense of imbalance. For people who have just received a diagnosis or who are working through repeated episodes, vertigo can feel frightening and exhausting — but it is one of the most common reasons people see an ear, nose, and throat (ENT) doctor or a neurologist, and most causes can be identified and treated.

This article is written for readers who already know that vertigo is part of their picture. It explains what vertigo is, the most common conditions that cause it, how doctors work out the underlying diagnosis, and the range of treatments — from simple bedside manoeuvres to medication, balance rehabilitation, and surgery in selected cases. It also covers what to expect over time, how to manage daily life during attacks, and when symptoms warrant urgent attention.

What Is Vertigo?

Vertigo is a specific kind of dizziness. The word “dizziness” is used loosely — it can mean lightheadedness, feeling faint, unsteadiness on the feet, or a true spinning sensation. Vertigo refers specifically to the spinning or movement illusion. You may feel that the room is rotating, that the ground is tilting, or that you are being pulled sideways.

This illusion comes from a mismatch in the body’s balance system. Balance depends on three sources of information working together: the inner ear (the vestibular system), the eyes, and the position sensors in the joints and muscles. The brain blends these signals to give you a stable sense of where your body is in space. When one source sends a different message from the others — usually because of a problem in the inner ear or the brain pathways that handle balance — the result is vertigo.

Vertigo itself is a symptom, not a disease. Doctors approach it by trying to identify the underlying cause, because the cause determines the treatment. Causes are usually divided into two broad groups:

• Peripheral vertigo — problems in the inner ear or the vestibular nerve. This is the most common group and includes conditions such as benign paroxysmal positional vertigo (BPPV), Meniere’s disease, and vestibular neuritis.
• Central vertigo — problems in the brain or brainstem balance pathways. This group is less common but includes vestibular migraine, stroke affecting the brainstem or cerebellum, and certain other neurological conditions.

Distinguishing peripheral from central vertigo is one of the first tasks of a clinical assessment, because the implications and the treatment paths are different.

Common Causes of Vertigo

Several distinct conditions cause vertigo. Understanding which one is responsible helps explain why the symptoms behave the way they do and why a particular treatment has been suggested.

Benign Paroxysmal Positional Vertigo (BPPV)

The hallmark of BPPV is brief, intense spinning triggered by specific head positions — rolling over in bed, looking up to a high shelf, bending down, or lying back at the dentist. Episodes typically last less than a minute, although the unsteadiness and nausea afterwards can linger. Hearing is not affected.

BPPV is more common with increasing age and can also follow a head injury or a period of bed rest. It often resolves with simple repositioning manoeuvres that move the crystals back to where they belong.

Meniere’s Disease

Meniere’s disease is a chronic inner ear disorder linked to a build-up of fluid in the inner ear. The classic attack involves four features: vertigo lasting twenty minutes to several hours, fluctuating hearing loss (usually in one ear), tinnitus (ringing or buzzing), and a feeling of fullness or pressure in the affected ear.

Attacks can occur in clusters, with months of relative calm in between. Over years, the hearing loss can become more permanent. The cause is not fully understood, but several triggers — including high-salt diets, stress, and caffeine — are recognised in clinical practice.

Vestibular Neuritis and Labyrinthitis

Vestibular neuritis is inflammation of the vestibular nerve, often triggered by a viral infection. It causes sudden, severe, continuous vertigo that can last for days, accompanied by nausea, vomiting, and difficulty walking. Hearing is preserved.

Labyrinthitis is similar but also involves the hearing part of the inner ear, so it causes hearing loss alongside the vertigo. Both conditions usually peak over a few days, then improve over weeks as the brain adapts — a process called central compensation. Vestibular rehabilitation exercises help speed this recovery.

Vestibular Migraine

Vestibular migraine is an increasingly recognised cause of vertigo and is now considered one of the most common causes of recurrent vertigo. It is a form of migraine in which vertigo or imbalance is a main feature, sometimes with little or no headache. Episodes can last minutes to days and may be triggered by stress, poor sleep, certain foods, hormonal changes, or visual stimuli such as scrolling on a screen.

People with vestibular migraine often have a personal or family history of migraine headache. The diagnosis is made based on clinical patterns described by the Barany Society and the International Headache Society.

Other Causes

Less common but important causes include:

• Acoustic neuroma (vestibular schwannoma) — a slow-growing benign tumour on the vestibular nerve, usually causing gradual hearing loss and unsteadiness rather than dramatic vertigo attacks
• Perilymph fistula — an abnormal opening between the inner and middle ear, sometimes following injury or pressure changes
• Superior semicircular canal dehiscence — a thin or absent bone overlying part of the inner ear
• Stroke or transient ischaemic attack affecting the brainstem or cerebellum — a serious central cause that needs urgent recognition
• Medication side effects — certain antibiotics, chemotherapy drugs, and high doses of some other medicines can affect inner ear function
• Persistent postural-perceptual dizziness (PPPD) — a chronic functional dizziness that often develops after another vertigo condition has triggered it

Diagnosis

Because vertigo has many causes, diagnosis depends heavily on a careful history and physical examination. Tests are used to confirm or rule out specific conditions rather than as a first step.

The Clinical History

The doctor will ask detailed questions about your episodes:

• How long does each episode last — seconds, minutes, hours, or days?
• What triggers it — certain head positions, sounds, stress, particular foods?
• Are there ear symptoms such as hearing change, ringing, or fullness?
• Are there headaches or visual symptoms before or during attacks?
• Is there nausea, vomiting, or imbalance between episodes?
• Any recent infections, head injuries, or new medications?

The pattern of duration and triggers is often the strongest clue. Brief positional spins point to BPPV; hours-long attacks with hearing loss point to Meniere’s; days of constant vertigo after a viral illness suggest vestibular neuritis; and recurrent episodes with migraine features suggest vestibular migraine.

Physical and Bedside Examination

The clinician will examine the ears, check hearing informally, and look at eye movements. Several bedside tests are particularly useful:

• The Dix-Hallpike manoeuvre — the patient is moved from sitting to lying with the head turned, while the examiner watches the eyes for the characteristic eye movements (nystagmus) of BPPV
• The head impulse test, nystagmus assessment, and test of skew (HINTS examination) — used in acute, ongoing vertigo to help distinguish a peripheral cause such as vestibular neuritis from a central cause such as a stroke
• Gait and balance testing — how you walk and stand with eyes open and closed

Audiological and Vestibular Testing

When the cause is not clear or hearing involvement is suspected, additional tests may be arranged:

• Audiometry — a hearing test that maps which sound frequencies are affected
• Videonystagmography (VNG) or electronystagmography (ENG) — recordings of eye movements during specific tasks to assess the vestibular system
• Vestibular evoked myogenic potentials (VEMPs) — tests of specific inner ear pathways
• Video head impulse test (vHIT) — a precise way of measuring the function of individual semicircular canals
• Caloric testing — warm and cool water or air introduced into the ear canal to assess vestibular response

Imaging

Imaging is not routinely needed when the clinical picture is clear, but an MRI scan of the brain and the internal auditory canals may be requested if there is suspicion of a central cause, an acoustic neuroma, or another structural problem. CT scans are sometimes used to look at the bone around the inner ear.

Treatment by Cause

Treatment depends on the underlying diagnosis. The same word — vertigo — covers very different conditions, and what helps one cause may not help another.

Treating BPPV

BPPV is one of the most satisfying conditions to treat because a simple repositioning manoeuvre can resolve it within minutes. The most widely used technique is the Epley manoeuvre, a sequence of head and body positions performed by the clinician that guides the dislodged crystals back to their original location. Other techniques such as the Semont manoeuvre or the Lempert (barbecue) roll are used depending on which canal is affected.

According to current American Academy of Otolaryngology guidelines, repositioning manoeuvres are the first-line treatment for BPPV. Many people experience significant relief after one or two sessions, though BPPV can recur and the manoeuvre may need to be repeated. Home versions of these manoeuvres can be taught for people with recurrent episodes.

Medication is generally not recommended as a first-line treatment for BPPV; it can mask symptoms without fixing the underlying problem.

Treating Meniere’s Disease

Treatment of Meniere’s disease aims to reduce the frequency and severity of attacks and preserve hearing as much as possible. Doctors typically work through a stepped approach:

• Lifestyle adjustments — a low-salt diet, limiting caffeine and alcohol, managing stress, and keeping a symptom diary to identify triggers
• Medications — diuretics to reduce fluid retention; betahistine, which is widely used in many countries including India for symptom control; vestibular suppressants and anti-nausea medication during acute attacks
• Intratympanic injections — steroids or, for difficult cases, gentamicin injected through the eardrum into the middle ear, where it acts on the inner ear
• Surgery — reserved for severe, disabling cases that do not respond to other treatments (described further below)

Treating Vestibular Neuritis and Labyrinthitis

In the acute phase, treatment focuses on controlling the severe symptoms. Anti-nausea medication and short courses of vestibular suppressants are commonly used for the first few days. A short course of corticosteroids may be considered to reduce inflammation, though evidence on long-term benefit is mixed.

Beyond the first few days, vestibular suppressant medications are generally tapered off, because they can slow the brain’s natural process of compensation. The most important treatment is then vestibular rehabilitation therapy — structured exercises that retrain the brain to adjust to the changed vestibular signals.

Treating Vestibular Migraine

Treatment overlaps significantly with the treatment of migraine headache and is based on two strategies:

• Acute treatment for individual episodes, which may include triptans, anti-nausea medication, and rest in a dark, quiet room
• Preventive treatment for people with frequent attacks, which may include lifestyle measures (sleep hygiene, regular meals, hydration, identifying food and sensory triggers) and preventive medications such as beta-blockers, certain antidepressants, calcium channel blockers, or anti-seizure medications used at migraine doses

Vestibular rehabilitation can also help, particularly when imbalance persists between attacks.

Treating Other Causes

Acoustic neuromas are managed by an ENT or neurosurgical team and may be observed, treated with stereotactic radiation, or surgically removed depending on size and symptoms. Strokes affecting the balance pathways are treated as acute neurological emergencies. PPPD is treated with a combination of vestibular rehabilitation, cognitive behavioural therapy, and sometimes medications used in the treatment of anxiety and depression.

Vestibular Rehabilitation

Vestibular rehabilitation therapy (VRT) is a structured exercise programme delivered by a trained physiotherapist or audiologist. It is one of the most important treatments across many causes of vertigo, because it helps the brain adapt to a damaged or imbalanced vestibular system — a process called central compensation.

• Gaze stabilisation exercises — moving the head while focusing on a fixed target, to retrain the reflex that keeps vision steady during head movement
• Habituation exercises — deliberately exposing the body to movements that provoke mild symptoms, so the brain gradually learns to tolerate them
• Balance training — standing and walking exercises with progressive challenges, such as eyes closed, soft surfaces, or head turns while walking
• Functional retraining — activities that mimic daily tasks the patient finds difficult

VRT works best when practised consistently. Sessions are typically arranged once a week or every two weeks, with daily home exercises in between. Many people notice meaningful improvement within four to eight weeks, although some conditions need longer.

Surgical Treatments

Surgery is not a first-line treatment for vertigo. It is considered in selected situations — usually severe Meniere’s disease that has not responded to other measures, or specific structural problems such as superior canal dehiscence or an acoustic neuroma.

Procedures that may be offered for severe Meniere’s disease include:

• Endolymphatic sac procedures — surgery on a small sac in the inner ear, aimed at reducing fluid pressure
• Vestibular nerve section — cutting the balance part of the vestibular nerve while preserving hearing; this stops vertigo attacks from the affected ear and the brain compensates over time
• Labyrinthectomy — complete removal of the inner ear balance organ; this is highly effective at stopping vertigo from that ear but results in complete loss of hearing on that side, so it is reserved for people who already have very poor hearing in the affected ear

For superior semicircular canal dehiscence, surgical repair of the bony defect can be considered. For acoustic neuromas, microsurgical removal is one of the treatment options depending on tumour size, hearing status, and patient factors.

Whether surgery is appropriate is always a clinical decision made between the patient and the surgical team, taking into account symptom severity, hearing, and the response to non-surgical treatments.

Self-Management and Daily Life

While medical treatment addresses the underlying cause, there is also a great deal that you can do during day-to-day life to reduce the impact of vertigo.

During an Acute Attack

• Sit or lie down in a safe place. Try not to move suddenly.
• Fix your gaze on a stationary object if you can.
• Avoid bright lights and busy visual environments — these can make symptoms worse.
• Use anti-nausea or vestibular suppressant medication only as prescribed, and only for short periods.
• Once the worst has passed, get up slowly and stay near support until you feel steady.

Between Episodes

• Identify and reduce triggers — for example, salt intake in Meniere’s, or sleep disruption and certain foods in vestibular migraine.
• Keep a symptom diary noting the date, duration, triggers, and any associated symptoms. This helps your doctor adjust treatment.
• Continue vestibular exercises as prescribed, even on days when you feel fine.
• Stay hydrated, eat regular meals, and aim for consistent sleep patterns.
• Tell people around you what is happening — family, employers, and close colleagues — so that you have support when you need it.

Driving, Work, and Activities

Vertigo affects safety in many daily activities. During active phases, driving, climbing ladders, swimming alone, and operating machinery should generally be avoided. Your doctor can advise on when it is reasonable to resume these activities, based on the cause and how well it is controlled. Many people return to full activity once their condition is treated; others need to adapt some routines on a long-term basis.

What to Expect Over Time

• BPPV often resolves with repositioning, but recurs in a meaningful proportion of people over months or years. Recurrences can be re-treated.
• Vestibular neuritis and labyrinthitis usually improve over weeks. Some people are left with a sense of unsteadiness during quick head movements, which generally improves with vestibular rehabilitation.
• Meniere’s disease tends to be a long-term condition, with attacks that can come and go over years. Many people find that attacks reduce in frequency over time, although hearing loss in the affected ear may slowly progress.
• Vestibular migraine often responds well to a combination of trigger management and preventive treatment, but can fluctuate over the years much as headache migraine does.
• PPPD can be persistent without targeted treatment but often improves substantially with a combined rehabilitation and psychological approach.

For many people, the goal of treatment is good control rather than complete absence of symptoms. Most achieve a level of control that allows full participation in work, family, and social life.

Risks and Complications

Vertigo itself is not usually dangerous, but it can cause harm indirectly. Falls during an attack are an important risk, particularly in older adults, and can lead to fractures or head injuries. Driving with poorly controlled vertigo poses a clear safety risk. Persistent vertigo can also affect mood, with anxiety and depression developing in some people, especially when symptoms have lasted a long time.

Treatments also carry their own risks. Medications can have side effects including drowsiness and a feeling of dullness. Intratympanic gentamicin treatment carries a risk of further hearing loss. Surgical procedures carry the general risks of anaesthesia along with specific risks such as hearing loss, facial nerve injury, or cerebrospinal fluid leak depending on the operation. These risks are discussed in detail before any procedure is offered.

Vertigo in Children

Vertigo in children is less common than in adults but does occur. The causes are somewhat different. The most common include:

• Benign paroxysmal vertigo of childhood — brief, unexplained vertigo episodes in young children, considered a precursor of migraine; it usually resolves on its own as the child grows
• Vestibular migraine — can begin in childhood or adolescence
• Middle ear infections — common in children and can occasionally cause balance symptoms
• Head injury — a known trigger for BPPV and other vestibular symptoms at any age
• Inner ear infections or congenital inner ear differences

Diagnosis in children combines a careful history (often from parents and the child together), examination, and selected tests adapted to the child’s age and ability to cooperate. Treatment principles are similar to those in adults but doses, medications, and rehabilitation approaches are adjusted for paediatric care. A paediatric ENT specialist or paediatric neurologist usually leads care for children with persistent or severe vertigo.

When to Seek Urgent Care

Most vertigo is caused by inner ear problems that, while unpleasant, are not dangerous. However, some features point to a possible central cause — including stroke — that needs immediate medical attention. Seek urgent care if vertigo is accompanied by:

• Sudden severe headache, unlike previous headaches
• Weakness or numbness in the face, arm, or leg, particularly on one side
• Difficulty speaking or understanding speech
• Double vision or sudden loss of vision
• Difficulty swallowing
• Loss of coordination or inability to walk
• Loss of consciousness
• Recent significant head injury

These symptoms can indicate a stroke or other neurological emergency, where time-sensitive treatment makes a major difference.

Frequently Asked Questions

Is vertigo a disease?

No. Vertigo is a symptom that can be caused by many different conditions. Treatment depends on which condition is responsible, which is why a proper diagnosis is important.

Will my vertigo come back after treatment?

It depends on the cause. BPPV can recur in a meaningful proportion of people and is usually re-treated easily. Meniere’s disease tends to be a long-term condition with periods of attacks and remission. Vestibular neuritis usually resolves and does not typically recur. Vestibular migraine often follows a fluctuating long-term course.

Can stress cause vertigo?

Stress is not usually the direct cause of vertigo, but it can trigger or worsen attacks in conditions such as Meniere’s disease and vestibular migraine. Stress management is often part of overall treatment.

How long does a typical vertigo attack last?

This varies by cause — seconds in BPPV, minutes to hours in vestibular migraine, twenty minutes to several hours in Meniere’s disease, and continuous for days in vestibular neuritis. The pattern is one of the most useful clues for diagnosis.

Are vertigo medications safe to use long term?

Vestibular suppressant medications such as those used to control acute attacks are generally intended for short-term use, because long-term use can slow the brain’s natural adaptation. Other medications, such as preventive treatments for vestibular migraine or diuretics in Meniere’s disease, may be used long term under medical supervision.

Do I need an MRI scan?

Not always. Many causes of vertigo are diagnosed on clinical grounds without imaging. An MRI is generally recommended when there are features suggesting a central cause, when hearing loss is asymmetric, or when symptoms do not fit a typical inner ear pattern.

Can vertigo be cured?

Some causes can be effectively cured — BPPV often resolves with one or two repositioning sessions, and vestibular neuritis usually settles over weeks. Other causes, such as Meniere’s disease and vestibular migraine, are managed rather than cured, with the goal of good long-term control.

Is it safe to exercise when I have vertigo?

Exercise that is part of a vestibular rehabilitation programme is encouraged and is one of the most effective treatments for many causes of vertigo. Other physical activities are usually safe between episodes, but activities with a risk of falling or requiring sharp head movements may need to be modified during active phases.

Conclusion

Vertigo is a common symptom with many different causes, ranging from straightforward inner ear conditions to less common neurological problems. The same words — spinning, dizziness, imbalance — can describe BPPV, Meniere’s disease, vestibular neuritis, vestibular migraine, or other conditions, each with its own treatment path. Careful clinical assessment is usually more important than extensive testing in reaching the right diagnosis.

For most people with vertigo, the outlook is positive. Many causes respond well to simple treatments such as repositioning manoeuvres, lifestyle adjustments, vestibular rehabilitation, or medication. Long-term conditions can usually be controlled to a level that allows full daily life. Surgery is reserved for a small number of carefully selected situations. Understanding what type of vertigo you have, and working through a structured treatment plan with your specialist, is the path that most people find leads to meaningful improvement and renewed confidence.
