Advancements in Understanding Hyperemesis and Electrolyte Disturbances

Hyperemesis Gravidarum (HG) has a reported incidence of approximately 0.3–3% of pregnancies. Without prompt recognition and treatment, severe maternal dehydration, electrolyte abnormalities, cardiac arrhythmias, and potentially altered fetal neurodevelopment may result. Recently, HG made medical and general media news as new data has pinpointed 2 likely culprits of its origin- and neither one is estrogen. In this episode, we will discuss these 2 protein markers, and how researchers are looking to develop a genetic test for patients to predict HG. We will also summarize a new publication from Obstetrics & Gynecology (which was published on February 1, 2024) as an ACOG Clinical Expert Series on the inpatient management of HG.
