Hypothyroidism and pregnancy

Live Webinar

Hypothyroidism and pregnancy

E-learning Modules

Launch: 22 November 2024


The negative impact of thyroid hormone imbalances during conception and pregnancy on both mother and baby are well-documented. Despite the potential impact on the intellectual development of the baby, the diagnosis and treatment, particularly of subclinical hypothyroidism, is still controversial. This webinar will highlight the need for vigilance to case-find and monitor or treat women with hypothyroidism according to local guidelines.

The issue of trimester-specific reference ranges for thyroid stimulating hormone and free thyroid hormones that transcend inter-assay variability and other confounders (including ethnicity and iodine intake) [Gietka-Czernel, 2021] will also be discussed. Fixed reference ranges suggested by endocrine societies risk misclassifying some healthy pregnant women as hypothyroid, who are then treated unnecessarily, which can cause preterm delivery, gestational diabetes, hypertension and pre-eclampsia [Gietka-Czernel, 2021]. While treatment for subclinical hypothyroidism remains controversial, current recommendations do not support universal screening of low-risk women during pregnancy [Sullivan, 2019].

There is a high lifetime risk of developing permanent hypothyroidism post-partum in women with subclinical hypothyroidism before they were pregnant or who developed hypothyroidism in the first trimester [Peng, 2022]. The need for vigilance and periodic testing of these women will be discussed.
