Possible triggers of vocal cord dysfunction (VCD) and 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:

  • Strong odors/fragrances

  • Smoke

  • Heightened emotions (stress and anxiety)

  • Upper respiratory infections

  • Some vocal maneuvers (talking, singing, laughing)

  • Changes in temperature and humidity

  • Exercise.

People with VCD generally have symptoms that are limited to exercise, although occasionally other triggers can cause problems.

Sometimes the triggers are not identified.
