Hyperemesis gravidarum due to thyrotoxicosis

Abstract
A case of hyperemesis gravidarum at 9 weeks’ gestation is described for which no cause could initially be found. Intravenous feeding was needed as a life preserving measure and following improvement on this regime the patient went into a thyrotoxic crisis which was successfully diagnosed and treated. The continuing pregnancy and its outcome is described. The need for practitioners to remember vomiting as a presenting sign of thyrotoxicosis is stressed.
