The symptoms of cyclic vomiting syndrome include:

  • Severe vomiting that occurs several times per hour and lasts less than one week
  • Three or more separate episodes of vomiting with no apparent cause in the past year

Other symptoms during a vomiting episode may include:

  • Abdominal pain
  • Diarrhea
  • Fever
  • Dizziness

The intervals between vomiting episodes are generally symptom-free. But some people experience mild to moderate nausea or abdominal or limb pain between episodes.

Continued vomiting may cause severe dehydration that can be life threatening. Symptoms of dehydration include:

  • Thirst
  • Less urination
  • Paleness
  • Exhaustion and listlessness
