SymptomsBy Mayo Clinic staff
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
- Sensitivity to light
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:
- Less urination
- Exhaustion and listlessness
