Hyperemesis gravidarum (which occurs in 0.3-1% of
pregnancies)1
and gestational transient hyperthyroidism
(which occurs in 1-2% of pregnancies)3
are associated with
elevated hCG levels during pregnancy2
. It is important to
distinguish gestational transient hyperthyroidism from
Graves’ disease because the course, fetal outcomes,
management, and follow-up are different3
. Graves’ disease
should be suspected if there is presence of goitre1
and/or
persistent abnormal thyroid function test result after 20th
gestational week5
. Gestational transient hyperthyroidism
usually resolveed by then, when hCG levels decline3
.
The aim of this case report is to highlight the clinical
presentation and transient phenomenon of gestational
transient hyperthyroidism with hyperemesis gravidarum,
and also to emphasize on the recommended management.
