Dizziness

People experiencing dizziness may describe it as any of a number of sensations, such as:

• A false sense of motion or spinning (vertigo)
• Lightheadedness or feeling faint
• Unsteadiness or a loss of balance
• A feeling of floating, wooziness or heavy-headedness

These feelings may be triggered or worsened by walking, standing up or moving your head. Your dizziness may be accompanied by nausea or be so sudden or severe that you need to sit or lie down. The episode may last seconds or days and may recur.

When to see a doctor

Generally, see your doctor if you experience any recurrent, sudden, severe, or prolonged and unexplained dizziness or vertigo.

Get emergency medical care if you experience new, severe dizziness or vertigo along with any of the following:

• Sudden, severe headache
• Chest pain
• Difficulty breathing
• Numbness or paralysis of arms or legs
• Fainting
• Double vision
• Rapid or irregular heartbeat
• Confusion or slurred speech
• Stumbling or difficulty walking
• Ongoing vomiting
• Seizures
• A sudden change in hearing
• Facial numbness or weakness

Factors that may increase your risk of getting dizzy include:

• Age. Older adults are more likely to have medical conditions that cause dizziness, especially a sense of imbalance. They're also more likely to take medications that can cause dizziness.
• A past episode of dizziness. If you've experienced dizziness before, you're more likely to get dizzy in the future.

Dizziness can increase your risk of falling and injuring yourself. Experiencing dizziness while driving a car or operating heavy machinery can increase the likelihood of an accident. You may also experience long-term consequences if an existing health condition that may be causing your dizziness goes untreated.

If your doctor suspects you are having or may have had a stroke, are older or suffered a blow to the head, he or she may immediately order an MRI or CT scan.

Most people visiting their doctor because of dizziness will first be asked about their symptoms and medications and then be given a physical examination. During this exam, your doctor will check how you walk and maintain your balance and how the major nerves of your central nervous system are working.

You may also need a hearing test and balance tests, including:

• Eye movement testing. Your doctor may watch the path of your eyes when you track a moving object. And you may be given an eye motion test in which water or air is placed in your ear canal.
• Head movement testing. If your doctor suspects your vertigo is caused by benign paroxysmal positional vertigo, he or she may do a simple head movement test called the Dix-Hallpike maneuver to verify the diagnosis.
• Posturography. This test tells your doctor which parts of the balance system you rely on the most and which parts may be giving you problems. You stand in your bare feet on a platform and try to keep your balance under various conditions.
• Rotary chair testing. During this test you sit in a computer-controlled chair that moves very slowly in a full circle. At faster speeds, it moves back and forth in a very small arc.

In addition, you may be given blood tests to check for infection and other tests to check heart and blood vessel health.

Dizziness often gets better without treatment. Within a couple of weeks, the body usually adapts to whatever is causing it.

If you seek treatment, your doctor will base it on the cause of your condition and your symptoms. It may include medications and balance exercises. Even if no cause is found or if your dizziness persists, prescription drugs and other treatments may make your symptoms more manageable.

Medications

• Water pills. If you have Meniere's disease, your doctor may prescribe a water pill (diuretic). This along with a low-salt diet may help reduce how often you have dizziness episodes.
• Medications that relieve dizziness and nausea. Your doctor may prescribe drugs to provide immediate relief from vertigo, dizziness and nausea, including prescription antihistamines and anticholinergics. Many of these drugs cause drowsiness.
• Anti-anxiety medications. Diazepam (Valium) and alprazolam (Xanax) are in a class of drugs called benzodiazepines, which may cause addiction. They may also cause drowsiness.
• Preventive medicine for migraine. Certain medicines may help prevent migraine attacks.

Therapy

• Head position maneuvers. A technique called canalith repositioning (or Epley maneuver) usually helps resolve benign paroxysmal positional vertigo more quickly than simply waiting for your dizziness to go away. It can be done by your doctor, an audiologist or a physical therapist and involves maneuvering the position of your head. It's usually effective after one or two treatments. Before undergoing this procedure, tell your care provider if you have a neck or back condition, a detached retina, or blood vessel problems.
• Balance therapy. You may learn specific exercises to help make your balance system less sensitive to motion. This physical therapy technique is called vestibular rehabilitation. It is used for people with dizziness from inner ear conditions such as vestibular neuritis.
• Psychotherapy. This type of therapy may help people whose dizziness is caused by anxiety disorders.

Surgical or other procedures

• Injections. Your doctor may inject your inner ear with the antibiotic gentamicin to disable the balance function. The unaffected ear takes over that function.
• Removal of the inner ear sense organ. A procedure that's rarely used is called labyrinthectomy. It disables the vestibular labyrinth in the affected ear. The other ear takes over the balance function. This technique may be used if you have serious hearing loss and your dizziness hasn't responded to other treatments.

If you tend to experience repeated episodes of dizziness, consider these tips:

• Be aware of the possibility of losing your balance, which can lead to falling and serious injury.
• Avoid moving suddenly and walk with a cane for stability, if needed.
• Fall-proof your home by removing tripping hazards such as area rugs and exposed electrical cords. Use nonslip mats on your bath and shower floors. Use good lighting.
• Sit or lie down immediately when you feel dizzy. Lie still with your eyes closed in a darkened room if you're experiencing a severe episode of vertigo.
• Avoid driving a car or operating heavy machinery if you experience frequent dizziness without warning.
• Avoid using caffeine, alcohol, salt and tobacco. Excessive use of these substances can worsen your signs and symptoms.
• Drink enough fluids, eat a healthy diet, get enough sleep and avoid stress.
• If your dizziness is caused by a medication, talk with your doctor about discontinuing it or lowering the dose.
• If your dizziness comes with nausea, try an over-the-counter (nonprescription) antihistamine, such as meclizine or dimenhydrinate (Dramamine). These may cause drowsiness. Nondrowsy antihistamines aren't as effective.
• If your dizziness is caused by overheating or dehydration, rest in a cool place and drink water or a sports drink (Gatorade, Powerade, others).

Your family doctor or primary care provider will probably be able to diagnose and treat the cause of your dizziness. He or she you may refer you to an ear, nose and throat (ENT) specialist or a doctor who specializes in the brain and nervous system (neurologist).

Here's some information to help you get ready for your appointment.

What you can do

• Be aware of any pre-appointment restrictions. At the time you make the appointment, be sure to ask if there's anything you need to do in advance, such as restrict your diet. If you're scheduled for vestibular testing, your doctor will provide instructions regarding any medications to withhold the night before and what to eat on the day of testing.
• Be prepared to describe your dizziness in specific terms. When you have an episode of dizziness, do you feel like the room is spinning, or like you are spinning in the room? Do you feel like you might pass out? Your description of these symptoms is crucial to helping your doctor make a diagnosis.
• List any other health conditions or symptoms you have, including any that may seem unrelated to your dizziness. For example, if you have felt depressed or anxious recently, this is important information for your doctor.
• List key personal information, including any major stresses or recent life changes.
• Make a list of all prescription and over-the-counter medications, vitamins or supplements that you're taking.
• List questions to ask your doctor.

Your time with your doctor is limited, so preparing a list of questions ahead of time will help you make the most of your time together. For dizziness, some basic questions to ask your doctor include:

• What's the most likely cause of my symptoms?
• Are there any other possible causes for my symptoms?
• What tests do you recommend?
• Is this problem likely temporary or long lasting?
• Is it possible my symptoms will go away without treatment?
• What treatment options might help?
• Do I need to follow any restrictions? For example, is it safe for me to drive?
• Should I see a specialist?
• Is there a generic alternative to the medicine you're prescribing?
• Do you have any brochures or other printed material that I can take home with me? What websites do you recommend?

What to expect from your doctor

Your doctor will likely ask you a number of questions about your dizziness, such as:

• Can you describe what you felt the first time you had an episode of dizziness?
• Is your dizziness continuous, or does it occur in spells or episodes?
• If your dizziness occurs in episodes, how long do these episodes last?
• How often do your dizziness episodes occur?
• When do your dizzy spells seem to happen, and what triggers them?
• Does your dizziness cause the room to spin or produce a sensation of motion?
• When you feel dizzy, do you also feel faint or lightheaded?
• Does your dizziness cause you to lose your balance?
• Are your symptoms accompanied by a ringing or fullness in your ears (tinnitus) or trouble hearing?
• Does your vision blur?
• Is your dizziness made worse by moving your head?
• What medications, vitamins or supplements are you taking?

What you can do in the meantime

If you tend to feel lightheaded when you stand up, take your time making changes in posture. If you have had episodes of dizziness while driving, arrange for alternate transportation while you're waiting to see your doctor.

If your dizziness causes you to feel like you might fall, take steps to reduce your risk. Keep your home well lighted and free of hazards that might cause you to trip. Avoid area rugs and exposed electrical cords. Place furniture where you're unlikely to bump into it, and use nonslip mats in the bathtub and on shower floors.
