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