Vocal Cord Dysfunction (VCD): Triggers

Possible triggers of vocal cord dysfunction (VCD) [or paradoxical vocal fold motion (PVFM)] are often similar to asthma triggers. However, it is important to know that not all people who experience VCD have asthma.

The following are some common triggers for VCD:

• Upper respiratory infections
• Exposure to airborne irritants (e.g., pollution, chemicals, allergens)
• Post-nasal drip
• Gastroesophageal reflux (GER) or Gastroesophageal reflux disease (GERD)
• Laryngopharyngeal reflux (i.e., "silent reflux")
• Strong odors or fumes
• Cigarette/fire smoke
• Exercise/exertion
• Singing
• Laughing
• Environmental change (e.g., cold air, change in temperature or moisture)
• Heightened emotions
• Stress/anxiety/tension
