Many causes.: Dizziness can be either vertigo (sensation of things moving) or light-headed. There are many possible causes of vertigo. These range from inner ear problems (vestibulitis, benign paroxysmal positional vertigo) to vestibular migraines to problems with the brainstem (such as strokes). Light-headedness can be caused by standing up too quickly, dehydration, or low blood counts.
