Cyclic vomiting syndrome is a disorder characterized by multiple recurring episodes of nausea and vomiting. It can sometimes be severe enough to lead to dehydration. In between episodes, patients typically have no symptoms. Chronic marijuana use has been associated with some cases. Physician and emotional stress, menstruation, fasting, infections, and certain foods have been identified as potential triggers for symptoms. Treatment for episodes can include fluid and electrolyte replacement and anti-nausea medications.
