Diagnosing Menieres disease in the UK involves a combination of clinical history, hearing assessments, and specialised balance tests. Because there is no single blood test that can definitively confirm the condition, specialists rely on a pattern of symptoms and objective test results to reach a diagnosis. The process is designed to confirm the presence of fluid pressure in the inner ear while ruling out other potential causes of vertigo and hearing loss.
The diagnostic pathway usually begins with a GP referral to an ENT (Ear, Nose, and Throat) specialist or an audio vestibular physician. These specialists use a variety of tools to measure how well the inner ear is functioning. Identifying the characteristic low frequency hearing loss and vestibular weakness is essential for confirming Menieres and developing a long term management plan to protect your hearing and stability.

Pure tone audiometry and hearing patterns
The first and most important test for Menieres disease is a hearing test called pure tone audiometry. This test measures the quietest sounds you can hear at different frequencies. In the early stages of Menieres, the results typically show a very specific type of sensorineural hearing loss that affects the lower frequencies (bass sounds) more than the higher ones.
This pattern is highly characteristic of the fluid buildup found in Menieres. Your audiologist will often perform this test multiple times over several months because the hearing loss in Menieres is known to fluctuate. Seeing the hearing drop during or after an attack and then partially recover is a key indicator that the issue is related to fluid pressure within the cochlea.
Vestibular and balance assessments
Because Menieres affects the balance part of the inner ear, specialised balance tests are used to check for vestibular weakness. These tests help determine which ear is affected and how much damage has occurred to the balance sensors.
- Caloric Testing: This involves gently swirling warm or cool air or water in the ear canal to trigger a balance response. In Menieres, the affected ear often shows a reduced response compared to the healthy ear.
- Video Head Impulse Test: This uses specialised goggles to track eye movements while your head is moved quickly. It provides a detailed look at how well each of the six semicircular canals is functioning.
- VEMP Testing: Vestibular Evoked Myogenic Potentials measure the response of the neck or eye muscles to sound. This helps specialists assess the function of the otolith organs, which are often affected by Menieres fluid pressure.
Ruling out other causes with MRI
In some specialised centres, a specific type of high resolution MRI using a contrast agent can sometimes show the actual fluid buildup within the inner ear. While this is not yet a routine test in every hospital, it is an emerging tool that provides a more direct way of visualising the physical changes associated with the disease.
Comparison: Diagnostic Tests for Menieres
| Test Type | What It Measures | Why It Matters for Menieres |
| Audiometry | Hearing thresholds | Detects low frequency hearing loss |
| MRI Scan | Brain and nerve anatomy | Rules out tumours or neurological issues |
| Caloric Test | Inner ear balance response | Identifies which ear has a weakness |
| ECoG | Electrical activity in the ear | Detects abnormal fluid pressure |
| Speech Test | Clarity of words | Measures impact of hearing distortion |
| VEMP | Muscle response to sound | Checks the gravity sensing parts of the ear |
To Summarise
Diagnosing Menieres disease in the UK is a thorough process that focuses on proving a pattern of fluctuating hearing loss and vestibular weakness. By combining audiometry results with balance tests and imaging, specialists can confirm the diagnosis with a high degree of accuracy. While the process can take time due to the fluctuating nature of the symptoms, these tests are essential for ensuring that you receive the correct treatment and support for your specific inner ear condition.
If you experience a sudden and complete loss of hearing in one ear, you should seek urgent medical advice from your GP or an A and E department.
How long does it take to get a final diagnosis?
Because the symptoms must be observed over time and hearing loss must be proven to fluctuate, it can often take several months or multiple attacks before a definite diagnosis is made.
Is the caloric test uncomfortable?
Some people find that the caloric test causes a brief sensation of vertigo and nausea, but this usually passes within a few minutes once the test is finished.
Can I have Menieres if my MRI is normal?
Yes. In fact, most people with Menieres have a normal MRI because the scan is used to rule out other problems rather than to see the Menieres itself.
What is the difference between definite and probable Menieres?
A definite diagnosis requires proven hearing loss and at least two spontaneous attacks of vertigo. A probable diagnosis is used when the symptoms fit the pattern but hearing loss has not yet been captured on a test.
Do I need to stop my vertigo medication before the tests?
Yes, you are usually asked to stop taking vestibular suppressants like prochlorperazine for 48 hours before balance tests, as they can interfere with the results.
Will a blood test help diagnose Menieres?
Blood tests are not used to diagnose Menieres, but they may be ordered to check for other conditions like diabetes, thyroid issues, or autoimmune disorders that can cause similar symptoms.
