[Pregnancy and thyroid disorders]. / Pathologies thyroïdiennes et grossesse.

ABSTRACT

Thyroid disorders are frequent among women, with a few specificities during pregnancy. Recent guidelines from the Endocrine Society concerning the management of thyroid disorders during pregnancy have been published, one year after the guidelines published by the American Thyroid Association. Iodine deficiency in France can increase the development of thyroid disorders during pregnancy. Hypothyroidism during pregnancy must be correctly substituted to avoid fetal complications. Maternal hyperthyroidism should be explored and monitored following a specific defined modality to discuss the necessity of a treatment and to prevent maternal and fetal complications. In case of thyroid nodes or cancer, the follow-up will not differ from non-pregnant women. However in most of cases, involvement of a multidisciplinay team might be necessary.
