Early Detection of Thyroid Issue During Pregnancy Linked to Higher Risk of Pregnancy Loss

Subclinical Hypothyroidism Diagnosed Before 21 Weeks Associated with Increased Risk

Study Highlights Importance of Prenatal Screening and Treatment

Pregnant women with a mild form of hypothyroidism known as subclinical hypothyroidism (SCH) diagnosed before 21 weeks of pregnancy have a significantly higher risk of pregnancy loss, according to a new study.

The study, published in the Journal of Clinical Endocrinology & Metabolism, found that women with SCH had a fourfold increased risk of pregnancy loss compared to euthyroid women (women with normal thyroid function).

"These findings highlight the importance of routine prenatal screening for and treatment of subclinical thyroid dysfunction," said lead author Dr. [Author's name]. "Early detection and treatment can help to reduce the risk of adverse pregnancy outcomes."

SCH is a condition in which the thyroid gland does not produce enough thyroid hormone, but not enough to cause symptoms. The study found that compared to euthyroid women, women with SCH had a higher risk of pregnancy loss (relative risk 2.01, 95% confidence interval 1.66-2.44).

The study's findings have led several professional organizations to recommend routine prenatal screening for and treatment of subclinical thyroid dysfunction.
