Maternal thyroid disorders during pregnancy require timely treatment to prevent adverse outcomes. Screening for thyroid dysfunction, even mild cases, is crucial for fetal neurodevelopment and maternal health.
Area of Science:
- Endocrinology
- Obstetrics
- Maternal-Fetal Medicine
Background:
- Thyroid gland physiology significantly changes during pregnancy.
- Thyroid hormone levels are gestational-age dependent.
- Accurate interpretation of thyroid hormone levels is vital for preventing pregnancy complications.
Purpose of the Study:
- Highlight the importance of timely thyroid disease treatment in pregnancy.
- Emphasize the need for screening subclinical hypothyroidism.
- Discuss the role of thyroid hormone levels in fetal neurodevelopment and postpartum thyroiditis.
Main Methods:
- Measurement of serum thyroid stimulating hormone (TSH) and free thyroxine.
- Utilizing gestation-age-specific TSH thresholds for diagnosis.
- Assessing thyroid peroxidase antibody (TPO Ab) and thyroglobulin autoantibody (TgAb) for postpartum thyroiditis prediction.
Main Results:
- Subclinical hypothyroidism can impact fetal neurodevelopment.
- Gestational iodine deficiency remains a concern in some regions.
- Thyroid peroxidase antibody and thyroglobulin autoantibody accurately predict postpartum thyroiditis.
Conclusions:
- Early diagnosis and treatment of maternal thyroid dysfunction are essential for positive maternal and fetal outcomes.
- Development of pregnancy-specific free thyroxine thresholds is needed.
- Large-scale trials are required to evaluate preconception and early pregnancy screening for thyroid disorders.

Hyperthyroidism I: Introduction
Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
