Miscarriage and Hypothyroidism

Miscarriage and Hypothyroidism

Miscarriage is extremely painful, studies state that one in four pregnancies end with a miscarriage. If you have ever suffered one, you know the sense of loss and the heartbreak. A slightly elevated TSH level, known as subclinical hypothyroidism, has shown an increased risk of miscarriage or the ability to even concieve at all. Women with pre-existing hypothyroidism need more medication during pregnancy, but many cases of hypothyroidism go undiagnosed prior to a woman becoming pregnant.

I can see why there is a problem with lack of treatment for subclinical hypothyroidism. The ranges for the standard TSH testing are too wide and even though there has been some adjustments, most doctors are not up to date with new thyroid testing. This is so sad because of the damage low thyroid hormone can cause a developing baby.

Hypothyroidism Linked to Miscarriage


Neonatal Thyroid Screening

Before neonatal screening became standard in the United States during the past 40 years, congenital hypothyroidism often went unrecognized in many children. Congenital hypothyroidism is one of the most common endocrine disorders present at birth, as well as the most common treatable cause of mental retardation.

The most common underlying etiology of congenital hypothyroidism is thyroid dysgenesis, failure of the gland to develop or fully develop. “The thyroid gland starts its development in the fetus at the base of the tongue, and it has to migrate down to its normal location in the middle of the neck. If it does not migrate normally, it is referred to as an ectopic gland,” Stephen H. LaFranchi, MD.

“With increased sensitivity and accuracy of [thyroid-stimulating hormone] methods, many U.S. and other programs around the world have switched from a primary thyroxine follow-up TSH approach to a primary TSH test,” the researchers wrote. We know “If the TSH cutoff is lowered, more infants with milder congenital hypothyroidism will be detected.”
