Lightheadedness, Dizziness, or Fainting

Common Causes of Each Symptom

• Lightheadedness : This can occur in everyday life due to fatigue or dehydration. However, it may also be a sign of anemia or autonomic nervous system dysfunction.
• Dizziness : There are two main types—rotational dizziness (often caused by inner ear problems) and non-rotational dizziness (which may be related to brain or autonomic nervous system disorders).
• Fainting (Syncope) : A temporary loss of consciousness caused by a brief reduction in blood flow to the brain.
  If triggered by fatigue or dehydration, it usually resolves within a few seconds and is not a major concern.
  However, if fainting occurs frequently or without an obvious cause, it may indicate a serious underlying condition.
