Cyclic Vomiting Syndrome (Episode 218)

from Primary Care Perspectives Hosted by Children’s Hospital of Philadelphia

In this episode, Haley Pearlstein, MD, a CHOP gastroenterologist, discusses cyclic vomiting syndrome (CVS), a pediatric condition marked by recurrent severe nausea and vomiting episodes separated by symptom-free intervals, with a prevalence of up to 3.2% in children. We cover typical presentation in primary care, NASPGHAN guidelines, differential diagnoses including CNS tumors, and diagnostic work-up strategies. In addition, we explore how acute treatments parallel migraine therapies, recommended lifestyle modifications, and preventive medications.
