What is dizziness?

Dizziness is a feeling of unsteadiness, wooziness, lightheadedness and vertigo (sensations of moving, spinning, floating, swaying, tilting or whirling). These sensations occur even when standing still or lying down.

More than 4 out of 10 people experience an episode of dizziness significant enough to send them to a doctor. Dizziness changes your sense of balance and can increase your risk of falling.
