Dizziness is an umbrella word for three quite different sensations, and naming yours correctly is most of the diagnosis. Vertigo is a spinning sensation. Lightheadedness is feeling faint. Disequilibrium is unsteadiness on your feet. Your doctor’s first question will be which one it is, so it is worth deciding before you go.
What Causes Each Type?
| Sensation | Common causes |
|---|---|
| Spinning (vertigo) | BPPV, vestibular neuritis, Meniere’s disease, vestibular migraine |
| Faint or woozy | Low blood pressure on standing, dehydration, anaemia, low blood sugar, medication |
| Unsteady | Inner ear problems, vision changes, neuropathy, muscle weakness |
The single most common cause of true spinning is benign paroxysmal positional vertigo — loose crystals in the inner ear. It lasts under a minute, is triggered by rolling over in bed or looking up, and is often fixed in one session with a repositioning manoeuvre.
Why Is Dizziness More Common in Women?
Several reasons stack up. Iron deficiency is far more prevalent in women, and anaemia causes lightheadedness long before it is picked up. Migraine, which affects women around three times as often as men, frequently presents as vertigo with little or no headache. And in perimenopause, fluctuating oestrogen affects blood pressure regulation and inner ear fluid balance, so episodes of wooziness are a genuinely common complaint in the mid-40s onward.
What Can You Do About It?
- Get bloods checked. Full blood count, ferritin, thyroid function, glucose and B12 explain a large share of cases. See why B12 matters.
- Stand up slowly and sit on the edge of the bed for a few seconds first.
- Hydrate properly and do not skip meals — both are frequent culprits and easily fixed.
- Review your medication list with a pharmacist. Blood pressure drugs, sedatives and some antidepressants are common contributors.
- Ask about vestibular rehabilitation for persistent balance problems. It works, and it is underused.
- Reduce fall risk in the meantime: good lighting, no loose rugs, and balance work such as single-leg stands.
When Is Dizziness an Emergency?
Call emergency services if dizziness comes with any of these:
- Sudden severe headache, or the worst headache of your life
- Double vision, slurred speech, or weakness or numbness on one side
- Chest pain, palpitations or breathlessness
- Fainting, or a fall with loss of consciousness
- New difficulty walking or a sudden loss of hearing
Frequently Asked Questions
Can dehydration alone make you dizzy?
Yes, easily — particularly in hot weather, after exercise, or alongside a very low calorie intake.
Is dizziness a sign of low iron?
It can be. Lightheadedness with fatigue, breathlessness on stairs and pale skin warrants a ferritin test, not just a haemoglobin.
Why do I feel dizzy when I stand up?
Usually orthostatic hypotension — blood pressure dipping briefly on standing. It is more common with dehydration, hot weather and certain medications, and worth mentioning to your doctor if it is frequent.
