Dizziness: Symptoms
Dizziness is a vague term describing a variety of sensations including:

• Lightheadedness
• Feeling like you might faint
• Being unsteady
• Losing balance
• Feeling that either you or the room is spinning or moving (vertigo)
• Nausea
• Fatigue
• Difficulty concentrating
  

The exact symptoms depend on the cause of the dizziness:

• Meniere's disease: symptoms include recurrent, severe attacks of vertigo, deafness and ringing in the ears.
  
• Benign positional vertigo (BPV): symptoms include episodes of vertigo triggered when the person's head is moved into specific positions
  
• Viral labyrinthitis: symptoms include the sudden onset of severe vertigo, nausea, vomiting and the need to remain still. It is often preceded by a cold or flu-like illness. This condition is thought to be caused by a viral infection of the inner ear.
  
• Migraine: dizziness is one of many symptoms migraneurs experience.
  

In rare cases, dizziness or feeling unsteady can be a sign of stroke, multiple sclerosis, seizures, a brain tumor, or bleeding in the brain. In these cases, other symptoms usually accompany the dizziness or imbalance.
