Meniere's Disease

Meniere's disease is a long-term disorder of the inner ear, which controls both hearing and balance. It causes episodes, sometimes called attacks, in which several symptoms occur together, typically affecting one ear, although it can later involve both.

The four characteristic features are vertigo (a spinning sensation), hearing loss that can come and go, tinnitus (ringing or buzzing in the ear), and a feeling of pressure or fullness deep inside the ear. Episodes can last from minutes to hours and may be followed by tiredness. Between episodes, people may feel well or have lingering symptoms such as some hearing loss or tinnitus.

The hallmark of Meniere's disease is recurring episodes that bring together vertigo, fluctuating hearing loss, tinnitus and a sense of fullness in the affected ear. The vertigo can be severe and may cause nausea or vomiting and difficulty keeping balance during an attack.

The pattern is what distinguishes Meniere's disease from some other inner ear problems. Unlike BPPV, where short bursts of vertigo are triggered by head position and there is no hearing loss, Meniere's episodes are not simply position-triggered and involve hearing changes, tinnitus and ear fullness alongside the vertigo.

The exact cause of Meniere's disease is not fully understood. It is thought to be related to a build-up of fluid in the inner ear, which disturbs the signals the ear sends to the brain about hearing and balance.

A number of factors have been suggested as possible contributors, but no single cause has been confirmed. Because the cause is uncertain, treatment focuses on controlling symptoms and reducing how often episodes occur rather than curing the underlying condition.

There is no single test for Meniere's disease, so diagnosis is based mainly on the typical pattern of repeated episodes combining vertigo, hearing loss, tinnitus and ear fullness. A clinician will ask in detail about the symptoms and examine the ears, head and neck.

Hearing tests are commonly used to document the hearing loss and how it fluctuates. Other tests, such as blood tests or an MRI scan, may be arranged to exclude other conditions that can cause similar symptoms. Referral to an ear, nose and throat or balance specialist is often part of confirming the diagnosis.

There is no cure for Meniere's disease, but a combination of approaches can help control symptoms and reduce the frequency of episodes. Medicines may be used to ease nausea and vertigo during an attack, and others may be tried to help prevent episodes. Lifestyle measures are an important part of management and often include reducing salt in the diet, staying well hydrated, and cutting back on caffeine and alcohol, with stopping smoking also encouraged.

For the hearing loss and tinnitus that can persist between episodes, hearing aids and tinnitus management strategies can help. Vestibular rehabilitation, a form of balance physiotherapy, can improve steadiness for people troubled by ongoing imbalance. In a small number of cases where symptoms are severe and other treatments have not helped, procedures or surgery on the inner ear may be considered.

During an episode of vertigo it is usually safest to stop what you are doing and sit or lie down somewhere secure until the spinning passes, as sudden vertigo can lead to falls. Keeping still, focusing on a fixed point, and avoiding driving or operating machinery until you feel steady again can all help.

If you experience new or unusual symptoms, such as a sudden severe headache, weakness, slurred speech, double vision or sudden complete hearing loss, seek urgent medical care, as these are not typical of a Meniere's episode and need prompt assessment.

Meniere's disease cannot be prevented, but identifying and reducing personal triggers, along with dietary and lifestyle measures, can help some people have fewer or milder episodes. Keeping a record of episodes can make it easier to spot patterns and adjust management.

The course of Meniere's disease varies from person to person. For many, episodes of vertigo become less frequent over time, although some degree of hearing loss or tinnitus in the affected ear may remain. With ongoing support, most people are able to manage the condition and maintain a good quality of life.
