Dizziness is a feeling of unsteadiness or lightheadedness. It may make you feel as though you or your surroundings are spinning or moving (which is known as vertigo), or it may simply give you a sensation of being off-balance or faint. This condition can be caused by various factors, including inner ear problems, medication side effects, dehydration, or anxiety.
The word "dizziness" comes from the Middle English word "dizzy," which means "faint" or "confused." It can be traced back to the Old English "dysig," meaning "foolish" or "dizzy," and has roots in the Proto-Germanic "*dūgiz," referring to a state of confusion or dizziness.
