Hello. : Hello. Dizziness is a very generalized symptom with many possible causes. Dizziness can be caused by dehydration. Try to ensure that you are drinking at least 8 8 ounce glasses of water per day. Dizziness can be a migraine headache symptom. Dizziness can occur with congestion that impacts the internal portion of the ear. Dizziness can occur if a person is really hypoglycemic. If your dizziness presents in a manner that makes it feel like things are spinning around you, this could be vertigo. I hope your symptoms resolvequickly, if it remains problematic, seek medical care.
