Dizziness is a common symptom that almost everyone will experience at some point in their lifetime.Â
Dizziness isn’t normally a sign of anything serious but there can be underlying causes of dizziness that you need to check out.
Causes of dizziness include:
- Common cold
- Migraine
- Motion (travelling in a car or on a boat)
- Nausea
- Shock, panic, severe emotion
- Stress
More serious causes of dizziness include:Â
- Head injury
- Heart problems
- Eye problems
- Ear problems
- Low blood pressure
- Low blood sugar
- Dehydration
- Anaemia
- Hyperventilation (rapid deep breathing)
Occasional dizziness is usually nothing to worry about but if you find that you are dizzy most of the time, or have regular attacks of dizziness for no apparent reason, it’s a good idea to see a doctor or specialist.
Vertigo is a more severe form of dizziness that describes a spinning or swaying sensation when you are standing still.Â
Vertigo may be because of inflammation, pressure or infection in the inner ear which may be due to several related conditions:
- Benign paroxysmal positional vertigo (BPPV) from calcium crystals (canalith) lodging inside the semicircular canal of your ear
- Inner ear inflammation linked to hearing loss
- Labyrinthitis, inflammation of the labyrinth of the inner ear due to a viral infection
- Vestibular neuritis, inflammation of the vestibular nerve inside the ear due to a viral infection
- Meniere’s disease due to fluid pressure in the ear causing vertigo, tinnitus and hearing loss
More rarely vertigo can be a symptom of severe migraine, stroke or multiple sclerosis (MS). Vertigo can arise due to a disturbance of blood flow in the brain or because of nerve inflammation.Â
If you have difficulty walking or speaking while experiencing vertigo it may be a sign of a stroke and you should seek immediate medical attention.
