Dizziness

Dizziness, or lightheadedness, is a feeling of unsteadiness. Dizziness can lead to feeling faint or to fainting (brief loss of consciousness).

Dizziness can be caused by many things, including stress and/or problems with brain functions.

Dizziness often goes away or improves after lying down. If it does not, it may be linked with conditions related to the inner ear or brain function.
