Dizziness, a blanket term used to describe any feeling of unsteadiness, is one of the leading health complaints in the United States, affecting an estimated nine million people annually. For those over the age of 70 it’s the top reason for a visit to the doctor’s office.
Dizziness is the result of your brain receiving false signals from the balance system (comprised of the inner ear, eyes and sensory nerves). It senses movement and overcompensates, leading to a spinning sensation, weakness and faintness. There are many possible causes of dizziness including low blood pressure, anemia, dehydration, heat-related disorders, endocrine system disorders (e.g., diabetes, thyroid disease), heart conditions, high blood pressure, viral and bacterial infections, head trauma, hyperventilation, neurological disorders and certain medications.
Several balance disorders are commonly associated with dizziness and/or vertigo. Benign Paroxysmal Positional Vertigo (BPPV) involves brief but intense periods of vertigo that are triggered by specific changes in head position. It occurs when tiny crystals in the otolith organs become dislodged and migrate to the semicircular canals. Meniere’s disease is a chronic condition that causes vertigo, tinnitus, fullness in the ear and fluctuating hearing loss that may eventually become permanent. Meniere’s is usually confined to one ear and though its cause is unknown it may be the result of abnormal fluid buildup in the inner ear. Labyrinthitis is an inflammation of the inner ear usually caused by an infection. Its symptoms include vertigo, temporary hearing loss and tinnitus.
Patients who experience dizziness report a variety of symptoms depending on the exact nature of their balance disorder. These include:
- Vertigo (the sensation of movement in your surroundings)
- Blurred vision
Treatment for dizziness takes many forms, depending on the cause. Your doctor will try to target the underlying condition in order to reduce or eliminate the symptoms. Options include medications (antihistamines, sedatives, antibiotics, steroids), physical or occupational therapy, surgery, repositioning exercises, vestibular retraining programs and lifestyle modifications such as dietary changes and elimination of alcohol and nicotine).
Ménière’s disease is an inner ear disorder that causes fluctuating hearing loss, tinnitus, vertigo and fullness or pressure in the ear. It is the result of excess fluid in the inner ear. There is no cure for Ménière’s disease, but various strategies can help you manage your symptoms.
The exact cause of Ménière’s disease is unknown. It is believed to be associated with a dysfunction of the endolymphatic sac, an organ responsible for regulating the volume and pressure of fluid in the inner ear. Various theories point to circulation disorders, viral infections, head trauma, allergies, migraines and obstructions of the ear canal as possible causes. It is estimated that Ménière’s disease affects about 1 out of every 1,000 people, with most patients between the ages of 40 and 60.
People with Ménière’s disease suffer progressive attacks that are often characterized by warning signs in advance. These include loss of balance, dizziness, headache, increased hearing loss and/or tinnitus, sensitivity to noises, and pressure in the ear. During the attack, you may experience episodes of severe vertigo, fluctuating hearing loss, fullness in the ear, and tinnitus. These symptoms may be accompanied by anxiety, blurry vision, nausea, vomiting, trembling, rapid pulse, and diarrhea. Afterwards, exhaustion often sets in, leading to an increased need for sleep. Attacks may be brief, lasting for as little as 20 minutes, or may persist for as long as 24 hours. Their frequency is unpredictable and sporadic; they may occur several times a week, or as little as once every few years. Due to the unpredictable nature of this disease, it’s impossible to tell just how much it will affect your life.
Because the symptoms of Ménière’s disease resemble those associated with other conditions, we will need to perform hearing and balance tests in order to make a diagnosis. An audiogram will show hearing loss in the low tones, a key indicator of Ménière’s disease. In some cases, imaging scans or blood tests are ordered.
Medical options for treating Ménière’s include motion sickness and anti-nausea medications, diuretics, an antibiotic called Gentamycin, and oral or injectable steroids. These, coupled with a low-sodium diet, can help prevent dizziness or reduce the severity of attacks. Other lifestyle remedies include limiting caffeine, alcohol, chocolate and monosodium glutamate from your diet; drinking six to eight glasses of water per day; quitting smoking; avoiding allergens; and reducing stress and anxiety.
When medications don’t work, you may benefit from vestibular rehabilitation exercises to improve balance. Hearing aids will help treat hearing loss associated with Ménière’s.
Individuals who experience severe attacks and are unable to find relief from other treatments may have success with surgery. Procedures that have proven effective include an endolymphatic sac procedure to drain fluid from the inner ear, a vestibular nerve section to cut the nerve that connects the ear and brain to eliminate dizziness and preserve hearing, and a labyrinthectomy to control dizziness.
