Research output: Contribution to journalArticlepeer-review


From the onset of pregnancy, the maternal thyroid undergoes physiological changes to its function. These are required to ensure a successful pregnancy and for normal offspring development to occur. It is therefore important to note that thyroid disorders can have significant impacts on the health of both mother and fetus. The most common of the thyroid conditions in pregnancy which has evidence of significant impact to the fetus are the hypothyroidism disorders. Hypothyroidism can be further categorised as overt or subclinical hypothyroidism. The epidemiology, pathophysiology of these conditions during pregnancy will be discussed in this review along with the associated significance of definitive pregnancy reference ranges to allow for measuring of the key thyroid hormones needed in the identification of thyroid disorders during pregnancy.
