Core Tip

Core tip: Hypothyroidism during pregnancy poses a significant health challenge as it is associated with adverse health outcomes for mother as well as the child. There is evidence that supports increased maternal and neonatal morbidity, even in absence of a clinically overt maternal hypothyroid state. However, in view of limited available healthcare resources, the jury is still divided regarding use of universal vs targeted screening programs in pregnant women. In addition, there is a lack of consensus regarding the best management approach for isolated hypothyroxinaemia and subclinical hypothyroidism. Keeping these contentious issues in mind, we have carried out a review of the literature.
