Meniere's disease is a disorder of the inner ear that causes spontaneous episodes of vertigo — a sensation of a spinning motion — along with fluctuating hearing loss, ringing in the ear (tinnitus), and sometimes a feeling of fullness or pressure in your ear. In many cases, Meniere's disease affects only one ear.
People in their 40s and 50s are more likely than people in other age groups to develop Meniere's disease, but it can occur in anyone, even children.
Although Meniere's disease is considered a chronic condition, various treatment strategies can help relieve symptoms and minimize the disease's long-term impact on your life.

The primary signs and symptoms of Meniere's disease are:
A typical episode might start with a feeling of fullness in your ear, increasing tinnitus and decreasing hearing followed by severe vertigo, often accompanied by nausea and vomiting. Such an episode might last 20 minutes to four hours, after which signs and symptoms improve. Episodes often occur in clusters, with long periods of mild or no symptoms (remission) between.
Still, the severity, frequency and duration of each of these sensory perception problems vary, especially early in the disease. For example, you could have frequent episodes with severe vertigo and only mild disturbances in other sensations. Or you may experience mild vertigo and hearing loss infrequently but have frequent tinnitus that disturbs your sleep.
See your doctor if you experience any signs or symptoms of Meniere's disease. Because any one of these problems may be the result of other illnesses, it's important to get an accurate diagnosis as soon as possible.
Vertigo is an uncommon but possible sign of other disorders, such as stroke, brain tumor, multiple sclerosis, or diseases of your heart or blood vessels (cardiovascular disease). See your primary care doctor immediately if vertigo is accompanied by any of the following signs or symptoms:

The cause of Meniere's disease isn't well understood. It appears to be the result of the abnormal volume or composition of fluid in the inner ear.
The inner ear is a cluster of connected passages and cavities called a labyrinth. The outside of the inner ear is made of bone (bony labyrinth). Inside is a soft structure of membrane (membranous labyrinth) that's a slightly smaller, similarly shaped version of the bony labyrinth. The membranous labyrinth contains a fluid (endolymph) and is lined with hair-like sensors that respond to movement of the fluid.
In order for all of the sensors in the inner ear to function properly, the fluid needs to retain a certain volume, pressure and chemical composition. Factors that alter the properties of inner ear fluid may help cause Meniere's disease. Scientists have proposed a number of potential causes or triggers, including:
Because no single cause has been identified, it's likely that Meniere's disease is caused by a combination of factors.

A diagnosis of Meniere's disease requires:
If you have signs or symptoms associated with Meniere's disease, your doctor will ask you questions about your sensory problems, order tests that evaluate the quality of inner ear function and order other tests to screen for possible causes of the problems.
Your doctor will conduct a physical examination and ask questions about:
A hearing test (audiometry) assesses how well you detect sounds at different pitches and volumes and how well you distinguish between similar-sounding words. The test not only reveals the quality of your hearing but also may help determine if the source of hearing problems is in the inner ear or the nerve that connects the inner ear to the brain.
Between episodes of vertigo, the sense of balance returns to normal for most people with Meniere's disease. But there may be some degree of ongoing balance problems.
There are several tests that assess function of the inner ear. Some or all of these tests can yield abnormal results in a person with Meniere's disease.
Videonystagmography (VNG). This test evaluates balance function by assessing eye movement. Balance-related sensors in the inner ear are linked to muscles that control movement of the eye in all directions. This connection is what enables you to move your head around while keeping your eyes focused on a single point.
In a VNG evaluation, warm and cool water or warm and cool air are introduced into the ear canal. Measurements of involuntary eye movements in response to this stimulation are performed using a special pair of video goggles. Abnormalities of this test may indicate an inner ear problem.

The unpredictable episodes of vertigo are usually the most debilitating problem of Meniere's disease. The episodes often force a person to lie down for several hours and lose time from work or leisure activities, and they can cause emotional stress.
Vertigo can also increase your risk of:

Certain self-care tactics can help reduce the impact of Meniere's disease. Consider these tips for use during an episode:
Modifying your diet can reduce your body's fluid retention and help decrease fluid in your inner ear. Your doctor may suggest you follow these dietary changes to lessen the severity and frequency of Meniere's disease symptoms:
Some evidence suggests that lifestyle factors may worsen symptoms of Meniere's disease or act as triggers for the onset of symptoms. Your doctor may recommend the following changes to alleviate symptoms or help prevent the onset of symptoms.

Meniere's disease may affect your interaction with friends and family, your productivity at work, and the overall quality of your life. You may find encouragement and understanding in a support group. Group members can provide information, resources, support and coping strategies. Your doctor may be able to recommend a group in your area, or you may find information about local groups from the Vestibular Disorders Association.
