Pregnancy complicated by cyclic vomiting syndrome.
BACKGROUND
Cyclic vomiting syndrome is a condition that consists of recurrent episodes of vomiting occurring between periods of normal health, with no apparent organic cause of vomiting. We report the sentinel case of pregnancy complicated by preexisting cyclic vomiting syndrome.


METHODS
A primigravida presented at 8 weeks of gestation with a complaint of protracted vomiting. She had been diagnosed previously with cyclic vomiting syndrome. An extensive workup was performed, and she was admitted for therapy numerous times during her pregnancy. She underwent an indicated preterm delivery for fetal growth restriction, oligohydramnios, and nonreassuring fetal testing. The neonate was discharged to home in stable condition.


CONCLUSIONS
Cyclic vomiting syndrome can complicate pregnancy, and the gravida with cyclic vomiting syndrome may be at risk for pregnancy complications. Increased surveillance may be warranted.
