The cause of cyclic vomiting syndrome is unknown. But the bouts of vomiting that characterize the syndrome can be triggered by:

  • Colds, allergies or sinus problems
  • Emotional stress or excitement, especially in children
  • Anxiety or panic attacks, especially in adults
  • Foods, such as chocolate or cheese
  • Overeating or eating right before going to bed
  • Hot weather
  • Physical exhaustion
  • Menstruation
  • Motion sickness

Identifying the triggers for vomiting episodes may help with managing cyclic vomiting syndrome.
