Dizziness (dizzy spells) is a feeling of light-headedness or unbalanced. Dizziness affects the sensory organs, mostly eyes, and ears, and can lead to fainting from dizziness.

Dizziness itself isn’t an illness, but a symptom of various underlying disorders like vertigo and disequilibrium. Occasional dizziness is nothing to worry about; however, if the person is experiencing frequent bouts of dizziness for no apparent reason or for a longer time, they should consult a doctor.

Migraine, medications, or alcohol may cause dizziness. A problem in the inner ear also may cause dizziness, where body balance is regulated. Dizziness is also caused by vertigo.
