The assessment of vertigo and balance disorders by a General Practitioner (GP) is a structured process designed to distinguish between simple inner ear issues and more complex neurological or cardiovascular conditions. In the UK, GPs follow clinical guidelines to determine the likely source of the dizziness and decide whether it can be managed in primary care or requires a specialist referral to an ENT (Ear, Nose, and Throat) consultant or a neurologist.
The most critical part of the assessment is the medical history. By understanding the exact nature of the sensation, its duration, and its triggers, a doctor can often narrow down the diagnosis before even beginning a physical exam. This initial consultation serves as the foundation for choosing the right physical tests to perform in the clinic to confirm the underlying cause.

The clinical history: Time and triggers
The duration of the episodes provides essential clues. Short bursts of spinning lasting seconds suggest Benign Paroxysmal Positional Vertigo (BPPV), while episodes lasting hours may point toward Menieres disease or vestibular migraines. Your doctor will also ask about associated symptoms such as hearing loss, tinnitus, or ear pressure, which are strong indicators of an inner ear origin.
Physical examination and ear inspection
Once the history is recorded, the GP will perform a physical examination. This starts with an inspection of the ears using an otoscope to look for signs of infection, fluid behind the eardrum, or impacted earwax. These are common and easily treatable causes of balance disruption.
The doctor will also check your cardiovascular health. This involves taking your blood pressure while you are sitting and again while you are standing, which is known as orthostatic blood pressure. A significant drop in pressure when standing can explain feelings of light headedness that mimic vertigo. They may also check your heart rate and rhythm to ensure the dizziness is not being caused by a cardiac issue.
Specialised bedside balance tests
To pinpoint the source of the vertigo, GPs use several specialised bedside tests. These are designed to trigger the symptoms under controlled conditions so the doctor can observe the body’s response.
- Dix Hallpike Manoeuvre: You will be asked to lie down quickly while your head is turned to one side. If this triggers spinning and specific eye movements, it confirms a diagnosis of BPPV.
- Romberg Test: You stand with your feet together and eyes closed. This tests how well your brain uses signals from your joints and inner ears when your vision is removed.
- HINTS Exam: This is a series of three eye movement tests used in urgent care to help distinguish between a simple ear issue and a more serious stroke at the back of the brain.
- Tandem Gait: The GP may ask you to walk heel to toe in a straight line to assess your coordination and neurological function.
Observation of Nystagmus
During these tests, the GP is looking closely at your eyes for nystagmus, which is a repetitive, uncontrolled eye movement. The direction and trigger of these movements are incredibly helpful. For example, eye movements that only happen after a specific head turn usually point to the ear. Eye movements that are constant or move straight up and down may indicate a central neurological issue that requires further investigation with imaging.
Comparison: Diagnostic Indicators in a GP Exam
| Feature | Suggests Inner Ear (Peripheral) | Suggests Brain or Nerve (Central) |
| Nystagmus | Horizontal or rotatory | Vertical or direction changing |
| Balance | Can stand with some support | Often unable to stand even with help |
| Hearing | Often affected (tinnitus or loss) | Usually normal |
| Neurological Signs | None present | Slurred speech or double vision |
| Onset | Sudden and severe | Can be sudden or gradual |
| Nausea | Often severe and distressing | Often mild or absent |
To Summarise
GPs assess vertigo by combining a detailed medical history with specific physical tests designed to challenge the balance system. By looking at your ears, checking your blood pressure, and observing your eye movements during head manoeuvres, they can usually determine if the issue is a mechanical ear problem or something requiring further specialist input. This structured approach ensures that the most common causes are identified quickly while serious neurological conditions are screened for and managed appropriately.
If you experience sudden vertigo accompanied by facial drooping, weakness in your limbs, or difficulty speaking, call 999 immediately.
Will I need a blood test for my vertigo?
Blood tests are not always necessary but can be used to rule out other causes of dizziness such as anaemia, low blood sugar, or thyroid issues.
Why does the doctor move my head so quickly?
Tests like the Dix Hallpike require a relatively quick movement to shift the fluid or crystals in your inner ear so the doctor can observe the resulting symptoms.
Can a GP treat vertigo during the appointment?
If you are diagnosed with BPPV, many GPs can perform a repositioning manoeuvre, like the Epley manoeuvre, during the same appointment to resolve the issue.
How long does a balance assessment usually take?
A thorough assessment typically takes between ten and twenty minutes, depending on the complexity of your symptoms and the number of tests required.
When will I be referred to a specialist?
Referrals are usually made if the diagnosis is unclear, if your hearing is significantly affected, or if the GP suspects a neurological cause that requires an MRI.
Should I take travel sickness medication before my appointment?
It is often better not to take these medications before your assessment, as they can suppress your eye movements and make it harder for the doctor to get an accurate test result.
