Because of the immunosuppressive effect of pregnancy, antithyroid drugs can be given in doses lower than with non pregnant patients. Over treatment of the hyperthyroidism with antithyroid drugs can affect the babys thyroid since the drugs cross the placenta into the babys bloodstream.Screening is performed by measuring the TSH level. Breast Feeding and Thyroid Disease Radioactive isotopes are secreted in milk therefore no isotope tests or isotope scans should be performed on someone who is breastfeeding.
Infertility Patients with either hyper- or hypothyroidism can have fertility problems although it is certainly possible to have these diseases and still get pregnant. Once the diseases have been treated, it is important to recommence birth control (if desired since fertility is restored quickly once the patients thyroid function is normal.Antithyroid drugs can be used when breast feeding, as only negligible amounts actually get into the milk. Thyroxine is also secreted in the milk, but providing the dosage in the mother is in the physiologic range, it appears to be quite safe for the mother on thyroxine to breast feed.
Sub-clinical hypothyroidism can sometimes cause infertility and miscarriages and is, thus, usually treated in women of childbearing age that desire to become pregnant. In addition, both men and women with untreated thyroid disease often have decreased sexual desire (libido).As a result of the loss of this protective effect at the end of pregnancy, there is a tendency for thyroid disease to occur after delivery in those women who have had previous thyroid disease or who are at risk for developing thyroid disease.

This "post partum thyroiditis" tends to get better after a few weeks although recurrence in subsequent pregnancies and progression to permanent hypothyroidism is possible.TSH suppression was associated with an increased incidence of premature ventricular beats, an increased left ventricular mass index, and enhanced left ventricular systolic function. The clinical significance of these changes remains to be determined.
The mean daily thyroxine dose was 1.99 mcg/kg (range, 0.3 to 6.6 mcg/kg) with a mean duration of therapy of 20.4 years (range, less than 1 to 68 years). Women taking daily doses of 1.6 mcg/kg or more had significantly lower bone mineral density levels at the ultradistal radius, midshaft radius, hip, and lumbar spine.The preferred medication during pregnancy is Propylthiouracil. Although there is no clear causality link between Methimazole (Tapazole) and fetal problems (aplasia cutis, choanal atresia) its use is second line in North America during pregnancy.
It is generally recommended to wait six months after radioactive iodine treatment before becoming pregnant. One other cause of infertility in patients with thyroid disease is the uncommon condition of primary ovary failure.This is an autoimmune disorder, like Graves disease and Hashimotos thyroiditis, caused by proteins and white cells in the blood that attack proteins in the patients ovaries. This leads to the decreased size of the ovaries, the failure to ovulate, premature menopause, and infertility.
Thyroid hormones play an important role in fetal brain development, so the thyroid hormones provided by the mother during the first trimester of pregnancy are especially important. Thyroxine treatment is adjusted to obtain TSH levels specific to each trimester (less than 2.5 mIU/L in the first trimester or 3 mIU/L during the second and third.Screening during Pregnancy for Thyroid Disorders. Screening guidelines for thyroid disease differ among the various associations and expert groups. The Endocrine Society recommends screening for thyroid disorders in women at high risk: Women with prior thyroid disease or surgery, goitre, family history, positive thyroid antibodies, other autoimmune diseases, symptoms or signs suggestive of thyroid dysfunction.

Preferably, Graves disease should be treated with radioactive iodine or by surgery before pregnancy to avoid the use of antithyroid medication during pregnancy.However, estrogen use appeared to negate the adverse effects of thyroid hormone on bone mineral density. Higher rates of femur fractures have been found in males (p0.008) prescribed long-term thyroid hormone therapy as compared to controls in a case-control analysis of 23,183 patients, from the United Kingdom General Practice Research Database, prescribed thyroid hormone.
