Cyclic vomiting syndrome can cause these complications:

  • Dehydration. Excessive vomiting causes the body to lose water quickly. Severe cases of dehydration may need to be treated in the hospital.
  • Injury to the food tube. The stomach acid that comes up with the vomit can damage the tube that connects the mouth and stomach (esophagus). Sometimes the esophagus becomes so irritated it bleeds.
  • Tooth decay. The acid in vomit can corrode tooth enamel.
