Prognosis

Uncomplicated NVP

Prognosis is excellent. Uncomplicated NVP typically resolves by the 20th week of gestation. Furthermore, women who experience NVP have been shown to have improved pregnancy outcomes. These include a decrease in miscarriages, pre-term deliveries, and stillbirths. In addition, there is a lower prevalence for reduced fetal birth weight, fetal growth restriction, and fetal mortality.[41][42][43]

Hyperemesis gravidarum

Hyperemesis may persist throughout the pregnancy and often requires ongoing pharmacological intervention, intravenous hydration, and hospital admission. In contrast with uncomplicated NVP, hyperemesis gravidarum is associated with an increase in maternal morbidity, and also increased fetal morbidity and mortality.[44][45][46][47] Additionally, patients may experience significant psychological impact from severe NVP.
