Cyclic vomiting syndrome (CVS) can complicate pregnancy, posing risks to both mother and fetus. This case highlights the need for increased surveillance in pregnant individuals with CVS.
Area of Science:
- Obstetrics and Gynecology
- Gastroenterology
- Perinatology
Background:
- Cyclic vomiting syndrome (CVS) is characterized by recurrent, unexplained vomiting episodes between periods of wellness.
- This report details a sentinel case of pregnancy complicated by pre-existing CVS.
Observation:
- A primigravida presented with severe vomiting at 8 weeks gestation, with a prior CVS diagnosis.
- The patient required multiple hospital admissions for management during pregnancy.
- Complications included fetal growth restriction and oligohydramnios, necessitating preterm delivery.
Findings:
- Pregnancy can be significantly complicated by underlying cyclic vomiting syndrome.
- Maternal CVS may increase the risk of adverse pregnancy outcomes.
- Neonatal outcome was stable following indicated preterm delivery.
Implications:
- Pregnant individuals with CVS require heightened clinical surveillance.
- Early recognition and management of CVS in pregnancy are crucial.
- Further research into CVS management during gestation is warranted.
