Assessment and Management of Nausea and Vomiting during Pregnancy: A Biopsychosocial Approach

David McCormack, Leroy Edozien

Research output: Chapter in Book/Report/Conference proceedingChapter (peer-reviewed)peer-review


Nausea and vomiting are very common symptoms
experienced during pregnancy, with approximately
80% of pregnant women experiencing some vomiting
and/or nausea and 52% having both nausea and
vomiting [1]. A smaller number of pregnant women,
approximately 0.3 to 1.5%, will experience hyperemesis
gravidarum (HG), which is a severe and intractable
form of nausea and vomiting during pregnancy
(NVP), typically starting between the fourth and sixth
weeks of gestation and resolving before the end of the
22nd week, with around 13% reporting it as lasting
beyond 20 weeks’ gestation [1–3]. NVP is associated
with negative physical, social and psychological effects
[4–6]. Severe and persistent vomiting, particularly if
left untreated, can lead to maternal weight loss, dehydration
and electrolyte imbalance; if electrolyte disturbance
occurs, there is some evidence that this
presents an elevated risk of lower birth weight and
fetal anomalies [7–9].
