Meniere’s disease is a chronic disorder of the inner ear that affects both balance and hearing. Named after the French physician Prosper Ménière, who first described the condition in the 19th century, this disease is characterized by episodes of vertigo, tinnitus, fluctuating hearing loss, and a feeling of fullness in the ear. Over time, repeated attacks can result in progressive hearing loss and reduced quality of life.
Pathophysiology of Meniere’s Disease
The underlying cause of Meniere’s disease is endolymphatic hydrops—an abnormal accumulation of fluid (endolymph) within the inner ear’s membranous labyrinth. This excess fluid interferes with the normal functioning of the cochlea (hearing) and vestibular system (balance).
- The condition usually affects one ear (unilateral) but can progress to both ears.
- The disease is episodic, meaning symptoms appear suddenly and may subside for days, weeks, or even months before returning.
- Over time, repeated damage to the auditory and vestibular structures can lead to permanent hearing loss.
Key Mechanisms:
- Excess Endolymph Production – The body produces more inner ear fluid than it can absorb.
- Obstruction in Endolymphatic Ducts – Blockages prevent proper drainage.
- Pressure Fluctuations – Sudden changes in ear pressure trigger vertigo and balance disturbances.
Signs and Symptoms of Meniere’s Disease
Meniere’s disease is marked by a classic triad of symptoms:
- Tinnitus – Persistent ringing, buzzing, or roaring sound in the ear.
- Unilateral Hearing Loss – Usually affects one ear and fluctuates during attacks before progressing to permanent hearing loss.
- Vertigo – Sudden spinning sensation leading to dizziness, nausea, vomiting, and loss of balance.
Other possible symptoms include:
- Aural fullness (feeling of pressure in the ear)
- Sudden falls (drop attacks)
- Headaches and visual disturbances during vertigo episodes
- Fatigue and anxiety due to unpredictable attacks
NCLEX Tip: Patients with Meniere’s disease are considered high risk for falls due to sudden vertigo episodes.
Risk Factors and Triggers
While the exact cause is unknown, several factors may contribute to Meniere’s disease:
- Genetics – Family history of inner ear disorders
- Autoimmune conditions – Abnormal immune response affecting ear structures
- Infections – Viral or bacterial inner ear infections
- Migraines – High association with vestibular migraines
- Allergies – May worsen endolymphatic hydrops
Common triggers for attacks:
- High salt intake (sodium causes fluid retention)
- Caffeine and alcohol consumption
- Smoking
- Stress and fatigue
- Sudden changes in barometric pressure
Diagnosis of Meniere’s Disease
Diagnosing Meniere’s disease can be challenging since symptoms overlap with other vestibular disorders. A thorough evaluation includes:
1. Medical History and Physical Examination
- Documentation of vertigo episodes lasting 20 minutes to 12 hours
- Reports of hearing loss, tinnitus, and ear fullness
2. Audiometric Tests
- Pure-tone audiometry to measure degree of hearing loss
- Speech discrimination tests to assess clarity
3. Vestibular Testing
- Electronystagmography (ENG) or Videonystagmography (VNG) – Records involuntary eye movements during balance tests.
- Rotary-chair testing – Assesses vestibular response to rotation.
4. Imaging Studies
- MRI or CT scan to rule out brain tumodrs, multiple sclerosis, or acoustic neuroma.
Diagnostic Criteria (per American Academy of Otolaryngology):
- Two or more episodes of vertigo lasting 20 minutes or longer
- Documented hearing loss
- Tinnitus or ear fullness
- Exclusion of other causes
Treatment and Management of Meniere’s Disease
While there is no cure for Meniere’s disease, treatment focuses on reducing symptom severity, preventing attacks, and preserving hearing.
1. Lifestyle and Home Remedies
- Fall precautions – Change positions slowly, use handrails, and avoid driving during attacks.
- Dietary modifications – Low-sodium diet (<1500 mg/day) helps reduce fluid retention.
- Avoid triggers – Eliminate caffeine, alcohol, and smoking.
- Stress management – Yoga, meditation, and adequate sleep reduce frequency of attacks.
2. Medications
- Diuretics (e.g., hydrochlorothiazide) – Reduce fluid accumulation.
- Vestibular suppressants (meclizine, diazepam) – Control vertigo symptoms.
- Antiemetics (promethazine, ondansetron) – Relieve nausea and vomiting.
- Corticosteroids – Reduce inner ear inflammation.
3. Vestibular Rehabilitation Therapy (VRT)
- Physical therapy exercises to improve balance and reduce dizziness.
4. Invasive Treatments (for severe cases)
- Intratympanic injections – Gentamicin (to ablate vestibular function) or steroids.
- Endolymphatic sac surgery – Improves drainage and reduces pressure.
- Labyrinthectomy – Removes inner ear structures (used when hearing is already lost).
- Vestibular nerve section – Cutting nerve to stop vertigo while preserving hearing.
Complications of Meniere’s Disease
If left untreated or poorly managed, Meniere’s disease can lead to:
- Permanent hearing loss
- Chronic imbalance and risk of falls
- Drop attacks (Tumarkin’s otolithic crisis) – Sudden loss of balance without warning
- Emotional distress – Anxiety, depression, and reduced quality of life
Living with Meniere’s Disease
Managing Meniere’s disease requires a long-term lifestyle approach:
- Keeping a symptom diary to identify triggers
- Using hearing aids for progressive hearing loss
- Joining support groups for psychological well-being
- Educating family members to provide safety support during vertigo episodes

Frequently Asked Questions (FAQs)
Q1. Can Meniere’s disease be cured?
No, there is no permanent cure. However, lifestyle changes, medications, and surgical options can significantly reduce symptoms.
Q2. Is Meniere’s disease life-threatening?
The disease itself is not fatal, but sudden vertigo and falls can increase the risk of injury.
Q3. Can Meniere’s affect both ears?
It usually starts in one ear but can progress to both in about 15-40% of patients.
Q4. How long do Meniere’s attacks last?
Vertigo episodes typically last between 20 minutes and 12 hours.
Q5. Is Meniere’s disease related to migraines?
Yes, there is a strong association between vestibular migraines and Meniere’s disease, though they are distinct conditions.
