Missed Abortion Presented with Worsening Hyperemesis Gravidarum

Hyperemesis gravidarum (HG) is the most common cause of in-patient hospitalizations during the first half of pregnancy. The etiology of HG has not yet been elucidated, and the treatment is mainly symptomatic. Untreated severe HG can lead to catastrophic maternal complications such as cardiac arrhythmia and death. In contrast, the impact of untreated severe HG on the fetuses remains contradictory. Evidence suggested that HG may increase the risk of a small for gestational age (GA) fetus. We here report a case of 32-year-old nulliparous woman, GA of 14 weeks, who presented with worsening HG and later had a diagnosis of missed abortion. More research is needed to clarify the possibility of HG as a contributory cause of abortion.
