Symptoms
By Mayo Clinic staffCyclic vomiting syndrome causes severe vomiting, nausea and gagging — sometimes as often as 12 times an hour. Episodes in children generally last only a day or two, but adults can have symptoms for almost a week. Adults tend to have about four episodes a year, while children have about 12. Episodes typically begin late at night or first thing in the morning.
Other common signs and symptoms include pallor and exhaustion. Some people are also sensitive to light during cyclic vomiting episodes and may develop:
- Headache
- Fever
- Dizziness
- Diarrhea
- Abdominal pain
