A balance disorder is a condition that makes you feel unsteady or dizzy. If you are standing, sitting, or lying down, you might feel as if you are moving, spinning, or floating. If you are walking, you might suddenly feel as if you are tipping over.

About 15 percent of American adults (33 million) had a balance or dizziness problem in 2008. Balance disorders can be caused by certain health conditions, medications, or a problem in the inner ear or the brain. A balance disorder can profoundly affect daily activities and cause psychological and emotional hardship.

Other symptoms might include nausea and vomiting; diarrhea; changes in heart rate and blood pressure; and fear, anxiety, or panic. Symptoms may come and go over short time periods or last for a long time, and can lead to fatigue and depression.

Causes of balance problems include medications, ear infection, a head injury, or anything else that affects the inner ear or brain. Low blood pressure can lead to dizziness when you stand up too quickly. Problems that affect the skeletal or visual systems, such as arthritis or eye muscle imbalance, can also cause balance disorders. Your risk of having balance problems increases as you get older.

Your sense of balance relies on a series of signals to your brain from several organs and structures in your body, specifically your eyes, ears, and the muscles and touch sensors in your legs. The part of the ear that assists in balance is known as the vestibular system, or the labyrinth, a maze-like structure in your inner ear made of bone and soft tissue.

Within the labyrinth are structures known as semicircular canals. The semicircular canals contain three fluid-filled ducts, which form loops arranged roughly at right angles to one another. They tell your brain when your head rotates. Inside each canal is a gelatin-like structure called the cupula [KEW-pyew-lah], stretched like a thick sail that blocks off one end of each canal. The cupula sits on a cluster of sensory hair cells. Each hair cell has tiny, thin extensions called stereocilia that protrude into the cupula.

When you turn your head, fluid inside the semicircular canals moves, causing the cupulae to flex or billow like sails in the wind, which in turn bends the stereocilia. This bending creates a nerve signal that is sent to your brain to tell it which way your head has turned.

Between the semicircular canals and the cochlea (a snail-shaped, fluid-filled structure in the inner ear) lie two otolithic [oh-toe-LITH-ic] organs: fluid-filled pouches called the utricle [YOU-trih-cull] and the saccule [SACK-kewl]. These organs tell your brain the position of your head with respect to gravity, such as whether you are sitting up, leaning back, or lying down, as well as any direction your head might be moving, such as side to side, up or down, forward or backward.

The utricle and the saccule also have sensory hair cells lining the floor or wall of each organ, with stereocilia extending into an overlying gel-like layer. Here, the gel contains tiny, dense grains of calcium carbonate called otoconia [oh-toe-CONE-ee-ah]. Whatever the position of your head, gravity pulls on these grains, which then move the stereocilia to signal your head's position to your brain. Any head movement creates a signal that tells your brain about the change in head position.

When you move, your vestibular system detects mechanical forces, including gravity, that stimulate the semicircular canals and the otolithic organs. These organs work with other sensory systems in your body, such as your vision and your musculoskeletal sensory system, to control the position of your body at rest or in motion. This helps you maintain stable posture and keep your balance when you're walking or running. It also helps you keep a stable visual focus on objects when your body changes position.

When the signals from any of these sensory systems malfunction, you can have problems with your sense of balance, including dizziness or vertigo. If you have additional problems with motor control, such as weakness, slowness, tremor, or rigidity, you can lose your ability to recover properly from imbalance. This raises the risk of falling and injury.

Diagnosis of a balance disorder is difficult. To find out if you have a balance problem, your primary doctor may suggest that you see an otolaryngologist and an audiologist. An otolaryngologist is a physician and surgeon who specializes in diseases and disorders of the ear, nose, neck, and throat. An audiologist is a clinician who specializes in the function of the hearing and vestibular systems.

You may be asked to participate in a hearing examination, blood tests, a video nystagmogram (a test that measures eye movements and the muscles that control them), or imaging studies of your head and brain. Another possible test is called posturography. For this test, you stand on a special movable platform in front of a patterned screen.

Posturography measures how well you can maintain steady balance during different platform conditions, such as standing on an unfixed, movable surface. Other tests, such as rotational chair testing, brisk head-shaking testing, or even tests that measure eye or neck muscle responses to brief clicks of sound, may also be performed. The vestibular system is complex, so multiple tests may be needed to best evaluate the cause of your balance problem.

The first thing an otolaryngologist will do if you have a balance problem is determine if another health condition or a medication is to blame. If so, your doctor will treat the condition, suggest a different medication, or refer you to a specialist if the condition is outside his or her expertise.

If you have BPPV, your otolaryngologist or audiologist might perform a series of simple movements, such as the Epley maneuver, to help dislodge the otoconia from the semicircular canal. In many cases, one session works; other people need the procedure several times to relieve their dizziness.

If you are diagnosed with Mnire's disease, your otolaryngologist may recommend that you make some changes to your diet and, if you are a smoker, that you stop smoking. Anti-vertigo or anti-nausea medications may relieve your symptoms, but they can also make you drowsy. Other medications, such as gentamicin (an antibiotic) or corticosteroids may be used. Although gentamicin may reduce dizziness better than corticosteroids, it occasionally causes permanent hearing loss. In some severe cases of Mnire's disease, surgery on the vestibular organs may be needed.

Some people with a balance disorder may not be able to fully relieve their dizziness and will need to find ways to cope with it. A vestibular rehabilitation therapist can help you develop an individualized treatment plan.

Talk to your doctor about whether it's safe to drive, and about ways to lower your risk of falling and getting hurt during daily activities, such as when you walk up or down stairs, use the bathroom, or exercise. To reduce your risk of injury from dizziness, avoid walking in the dark. Wear low-heeled shoes or walking shoes outdoors. If necessary, use a cane or walker and modify conditions at your home and workplace, such as adding handrails.

NIDCD-funded scientists are also working to develop much-needed tests to appropriately diagnose balance disorders. Standardized tests will help doctors determine the best way to help individuals restore their sense of balance and quality of life. These tests will also help us understand how many people suffer from balance disorders, and track whether the sense of balance is restored following treatment.

Balance is the ability to distribute your weight in a way that lets you stand or move without falling, or recover if you trip. Good balance requires the coordination of several parts of the body: the central nervous system, inner ear, eyes, muscles, bones, and joints. Problems with any one of these can affect balance. Medical conditions can also affect balance. These include:

Because so many parts of the body are involved in maintaining balance, balance disorders may arise from a wide range of conditions. Medications can cause dizziness. Small nerve fibers in the feet become less sensitive, which can make people unsteady. Just having a severe cold can cause a temporary disruption of your inner ear balance. But physical changes due to aging are the most common reason for a lack of balance.

Eyesight is another important balance-related function, since we need a clear sense of our surroundings to stay on our feet (If you doubt this, try standing on one foot with your eyes closed). When someone develops vision problems, their ability to judge distances and depth of field can lead to their losing balance.

Throughout our muscles, joints and tendons, nerves called proprioceptors tell the brain about subtle changes in conditions that call for adjustments, as when you step onto a patch of ice. With lightning speed, the brain sends instructions for how to react. When our muscles and tendons are weak, stiff or slow, we are less likely to avoid a fall.

While things as simple as ear infection and allergies can disrupt equilibrium, loss of balance may be tied to more serious conditions. For some such illnesses, loss of balance is the primary symptom, but for others it may go largely overlooked thanks to seemingly more urgent issues.

Balance issues in elderly people are common and can result in severe injury from a fall. Any new balance issues or dizziness should prompt a call to your doctor. He or she will do a physical examination, with special attention paid to taking blood pressure lying and standing, watching you walk, and checking nerve sensitivity in your feet.

Depending upon the results of the physical, the doctor may refer you for further testing. An otolaryngologist or otologist might perform a hearing test to see how responsive the hairlike cells of the inner ear are. Age related changes of the inner-ear structures is a common cause of balance issues in seniors.
