Considerations:

Yawning is a normal response to fatigue and drowsiness, but excessive yawning can be caused by a vasovagal reaction and may indicate a heart problem.

Normal yawning may be induced when the brain or lungs are not getting enough oxygen (or when someone else yawns).

Common Causes:

• Drowsiness or weariness
• Disorders associated with excessive daytime sleepiness
• Vasovagal reaction
  • Heart attack
  • Aortic dissection
