What it is
Dizziness or lightheadedness describes a spectrum of sensations including unsteadiness, faintness, presyncope, and a floating or woozy feeling — distinct from vertigo (a false sense of rotational movement).

Patterns of Dizziness or Lightheadedness
Dizziness and lightheadedness are among the most prevalent presenting symptoms in primary care, encompassing several phenomenologically distinct experiences. Presyncope (lightheadedness, faintness, 'greying out') reflects transient cerebral hypoperfusion — from orthostatic hypotension (standing up too quickly), vasovagal syncope (emotional or pain trigger), cardiac arrhythmia, dehydration, or anaemia. Disequilibrium describes a sense of unsteadiness while standing or walking, without head sensation — typically from peripheral neuropathy, cerebellar dysfunction, or vestibular disorders. Non-specific dizziness describes a woozy, floating, or foggy sensation without a clearly rotational or presyncopal quality — often associated with anxiety, hyperventilation, medication effects, or persistent postural-perceptual dizziness (PPPD). Distinguishing these presentations from true vertigo (rotational sensation) is critical, as they have different aetiologies, investigations, and treatments.

The Evidence
Evidence context
Dizziness and lightheadedness cover several distinct experiences with different causes, investigations, and care pathways — understanding the type matters.
Overall pictureHigh evidence base
A common symptom with many causes — type matters most
Dizziness is one of the most frequent presentations in primary care, spanning presyncope, unsteadiness, and non-specific wooziness. Each subtype has distinct causes and evidence-supported approaches, making accurate characterisation the essential first step.
When to seek urgent assessmentSome causes of dizziness require prompt medical evaluation and should not be self-managed.
Sudden dizziness with neurological symptoms such as facial drooping, slurred speech, or limb weakness may indicate stroke or TIA — seek emergency care immediately. Dizziness during exercise with loss of consciousness requires cardiac assessment. New severe headache with dizziness, or persistent dizziness alongside new hearing loss, also warrant prompt professional review.
What the evidence supportsSeveral approaches have strong evidence, but they depend on correctly identifying the subtype of dizziness.
Orthostatic hypotension responds well to hydration, compression, and in some cases medication. Vasovagal episodes are managed with trigger avoidance and physical counter-manoeuvres. PPPD has evidence for vestibular rehabilitation, SSRIs, and CBT. Benign paroxysmal positional vertigo responds to the Epley manoeuvre, though this involves rotational vertigo rather than lightheadedness specifically.
Safety considerationsSome common responses to dizziness can inadvertently slow recovery.
Long-term use of antihistamine-based vestibular suppressants may impair the brain's natural compensation process and worsen chronic dizziness over time. Prolonged bedrest without a clear underlying reason similarly delays vestibular recovery. These approaches may be appropriate short-term in specific situations but should be guided by a qualified practitioner.
Understanding the subtypesPresyncope, disequilibrium, and non-specific dizziness are distinct experiences with different underlying mechanisms.
Presyncope — faintness or greying out — reflects reduced blood flow to the brain. Disequilibrium is unsteadiness without head sensation, often linked to neurological or vestibular causes. Non-specific dizziness, described as woozy or foggy, is frequently associated with anxiety, hyperventilation, or medication effects. Distinguishing these from true vertigo guides appropriate investigation and care.
Complementary approachesSome complementary options have traditional use and limited to modest evidence for specific dizziness types.
Ginger has both traditional use and some evidence supporting its role in motion sickness and vestibular-type dizziness. Ginkgo biloba is traditionally used for dizziness, though clinical evidence for non-vertiginous presentations is modest. These approaches are best considered alongside, not instead of, professional assessment — particularly where an underlying cause has not been established.
When to involve a practitionerPersistent or unexplained dizziness warrants professional assessment to identify the underlying cause.
A GP or physician is the appropriate first point of contact for new or recurring dizziness. Depending on findings, referral to neurology, cardiology, or a vestibular specialist may follow. Vestibular physiotherapists play a key role in rehabilitation for PPPD and related conditions. Self-managing without assessment risks missing treatable or time-sensitive causes.
