People use “dizzy” for everything from light-headedness to a room that will not stop spinning. Doctors separate these because the causes, and the treatments, are different.
What is vertigo?
Vertigo is a spinning sensation. It often starts in the inner ear, where tiny crystals or fluid-filled canals help the brain sense movement. When they misbehave, you feel as though you are moving even when you are still.
Common causes
BPPV, inner-ear inflammation and Ménière’s disease are frequent ENT causes. Many cases respond well to positional manoeuvres, medicines and exercises.
Red flags
Dizziness with weakness of a limb, slurred speech, double vision, a severe sudden headache or fainting needs emergency care, as it can point to a problem in the brain rather than the ear.
