Meniere's Disease
Also known as: Endolymphatic Hydrops
Meniere's disease is a chronic inner ear disorder characterized by recurring episodes of vertigo, fluctuating hearing loss, tinnitus, and a feeling of fullness in the affected ear. The exact cause is unknown but is associated with abnormal fluid buildup (endolymph) in the inner ear. Episodes can be debilitating and typically affect one ear, though both ears may eventually become involved.
Symptoms
Causes
- Abnormal accumulation of endolymphatic fluid in the inner ear
- Possible autoimmune component
- Genetic predisposition
- Viral infection of the inner ear
Risk Factors
- Age 40–60 years
- Family history of Meniere's disease
- Pre-existing autoimmune conditions
- History of head trauma or ear infections
- High sodium diet
Diagnosis
- Audiometry showing low- to mid-frequency sensorineural hearing loss
- Electronystagmography (ENG) or videonystagmography (VNG)
- Electrocochleography (ECoG)
- MRI to rule out acoustic neuroma or other structural causes
Treatment
- Low-sodium diet to reduce fluid retention
- Diuretics (hydrochlorothiazide, triamterene)
- Vestibular rehabilitation therapy
- Betahistine (used in many countries outside the US)
- Intratympanic steroid or gentamicin injections for refractory cases
- Endolymphatic sac decompression surgery in severe cases
Prevention
- Limit dietary sodium to less than 1,500–2,000 mg per day
- Manage stress through relaxation techniques
- Avoid caffeine, alcohol, and tobacco
- Stay well hydrated
When to See a Doctor
- Sudden onset of vertigo with hearing changes
- Hearing loss that worsens progressively
- Vertigo episodes that interfere with daily activities
- New tinnitus or ear pressure that persists
