Question 1

What is dizziness or lightheadedness?

Accepted Answer

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.

Question 2

What do people commonly experience with dizziness or lightheadedness?

Accepted Answer

Individuals often feel as if they might faint or lose balance.

Question 3

What lifestyle changes can help with dizziness or lightheadedness?

Accepted Answer

Rising slowly from seated or lying positions prevents orthostatic hypotension. Adequate hydration reduces vasovagal and dehydration-related lightheadedness. Eating regular meals prevents hypoglycaemic dizziness. Avoiding known syncope triggers (prolonged standing in heat, blood draws without lying) reduces vasovagal episodes. Reducing alcohol and caffeine improves vestibular stability.

Question 4

What integrative approaches support dizziness or lightheadedness?

Accepted Answer

Orthostatic hypotension: hydration, compression stockings, fludrocortisone, midodrine. Vasovagal syncope: trigger avoidance, physical counter-manoeuvres (leg crossing, tensing). Cardiac arrhythmia: device or pharmacological management. PPPD (persistent postural-perceptual dizziness): vestibular rehabilitation, SSRIs, CBT. Menière's disease: low-sodium diet, betahistine, intratympanic interventions. BPV (benign paroxysmal positional vertigo) responds to Epley manoeuvre — but is associated with rotational vertigo rather than lightheadedness per se.

Question 5

When should I seek professional support for dizziness or lightheadedness?

Accepted Answer

Seek urgent assessment for dizziness with loss of consciousness, dizziness with new neurological symptoms (weakness, speech difficulty, diplopia), or dizziness following trauma. Seek routine assessment for persistent or recurrent dizziness — ECG, blood pressure measurement (including lying and standing), full blood count, and glucose are appropriate first-line investigations.
