What Is The Interaction Between The Thyroid Function Of The Mother And The Baby

For the first 18-20 weeks of pregnancy, the baby is completely dependent on the mother for the production of thyroid hormone. By mid-pregnancy, the babys thyroid begins to produce thyroid hormone on its own. The baby, however, remains dependent on the mother for ingestion of adequate amounts of iodine, which is essential to make the thyroid hormones. The World Health Organization recommends iodine intake of 250 micrograms/day during pregnancy to maintain adequate thyroid hormone production. Because iodine intakes in pregnancy are currently low in the United States, the ATA recommends that US women who are planning pregnancy, pregnant, or breastfeeding should take a daily supplement containing 150 mcg of iodine.

What Are The Treatment Options For A Pregnant Woman With Graves’ Disease/ Hyperthyroidism

Mild hyperthyroidism often is monitored closely without therapy as long as both the mother and the baby are doing well. When hyperthyroidism is severe enough to require therapy, anti-thyroid medications are the treatment of choice, with PTU being preferred in the first trimester. The goal of therapy is to keep the mothers free T4 in the high-normal to mildly elevated range on the lowest dose of antithyroid medication. Addition of levothyroxine to ATDs is not recommended. Targeting this range of free hormone levels will minimize the risk to the baby of developing hypothyroidism or goiter. Maternal hypothyroidism should be avoided. Therapy should be closely monitored during pregnancy. This is typically done by following thyroid function tests monthly.

In patients who cannot be adequately treated with anti-thyroid medications , surgery is an acceptable alternative. Surgical removal of the thyroid gland is safest in the second trimester.

Radioiodine is contraindicated to treat hyperthyroidism during pregnancy since it readily crosses the placenta and is taken up by the babys thyroid gland. This can cause destruction of the gland and result in permanent hypothyroidism.

The hormones your thyroid creates play a key role in regulating your metabolism the way your body uses energy along with your temperature, weight, cholesterol levels and other key body functions.

Production of thyroid hormones, in turn, is regulated by levels of thyroid-stimulating hormone , generated by your pituitary gland . The levels of thyroid hormones in your blood naturally fluctuate throughout the day; usually, the pituitary gland responds by creating more or less TSH.

The management of each woman’s situation is considered individually after consultation with her physician. The benefits of treatment extend not only to pregnant women with hypothyroidism, but also to their children.

What Is The Natural History Of Graves’ Disease After Delivery

Pin on Conditions and Getting Pregnant

Graves disease typically worsens in the postpartum period or may occur then for the first time. When new hyperthyroidism occurs in the first months after delivery, the cause may be either Graves disease or postpartum thyroiditis and testing with careful follow-up is needed to distinguish between the two. Higher doses of anti-thyroid medications may be required during this time. As usual, close monitoring of thyroid function tests is necessary.

What Is Postpartum Thyroiditis

Postpartum thyroiditis is an inflammation of the thyroid that affects about 1 in 20 women during the first year after giving birth1 and is more common in women with type 1 diabetes. The inflammation causes stored thyroid hormone to leak out of your thyroid gland. At first, the leakage raises the hormone levels in your blood, leading to hyperthyroidism. The hyperthyroidism may last up to 3 months. After that, some damage to your thyroid may cause it to become underactive. Your hypothyroidism may last up to a year after your baby is born. However, in some women, hypothyroidism doesnt go away.

Not all women who have postpartum thyroiditis go through both phases. Some only go through the hyperthyroid phase, and some only the hypothyroid phase.

What Is The Link Between Iodine Deficiency And Thyroid Function In Pregnancy

Having too little iodine in your body is a common cause of low thyroid hormone levels. A study found that, on average, Australian women consume 100 micrograms of iodine a day. However, the World Health Organization recommends a daily intake of least 250 micrograms of iodine during pregnancy and breastfeeding.

Australian guidelines recommend that pregnant and breastfeeding women take a supplement containing 150 micrograms of iodine each day .

Check with your antenatal health provider if you are concerned about your iodine levels, particularly if you are taking supplements such as pregnancy or pre-natal vitamins and minerals.

Your pharmacist will also be able to guide you on the potential impact of your prescription and over-the-counter medicines and their potential impact on iodine absorption and thyroid function.

What Tests Are Used To Check Thyroid Function

Your doctor can detect unusual thyroid hormone levels with a blood test. Regular screening is recommended for those with a higher risk of thyroid dysfunction, such as pregnant women:

  • with symptoms of thyroid dysfunction
  • with their own or family history of thyroid disease
  • with previous thyroid surgery
  • who are severely overweight or obese
  • who are aged 30 or older

The Debate Over Universal Thyroid Screening

Get Pregnant fast controlling your Thyroid

In the United States, doctors tend only to screen women at high risk for thyroid dysfunction or those who have a history of autoimmune diseases or preterm deliveries.

Doctors tend to debate the screening based on cases when a women has no symptoms or abnormal or borderline thyroid tests. Treating borderline cases detected via a universal screening could risk patient anxiety and puts pressure on clinicians. Most noted is that evidence is lacking when it comes to the benefits of treating women with abnormal and borderline test results.

On the flip side, Taylor said that universal thyroid screening in early pregnancy could improve child IQ and reduce complications of pregnancy.

However, a consensus is unlikely to be reached without further controlled trials which recruit women pre-conception or as early as possible in pregnancy, he added.

What Are The Risks Of Graves’ Disease/ Hyperthyroidism To The Baby

The risks to the baby from Graves disease are due to one of three possible mechanisms:

  • UNCONTROLLED MATERNAL HYPERTHYROIDISM: Uncontrolled maternal hyperthyroidism has been associated with fetal tachycardia , small for gestational age babies, prematurity, stillbirths and congenital malformations . This is another reason why it is important to treat hyperthyroidism in the mother.
  • ANTI-THYROID DRUG THERAPY . Methimazole or propylthiouracil are the ATDs available in the United States for the treatment of hyperthyroidism . Both of these drugs cross the placenta and can potentially impair the babys thyroid function and cause fetal goiter. Use of either drug in the first trimester of pregnancy has been associated with birth defects, although the defects associated with PTU are less frequent and less severe. Definitive therapy may be considered prior to pregnancy in order to avoid the need to use PTU or methimazole in pregnancy. When ATDs are required, PTU is preferred until week 16 of pregnancy. It is recommended that the lowest possible dose of ATD be used to control maternal hyperthyroidism in order to minimize the development of hypothyroidism in the baby. Overall, the benefits to the baby of treating a mother with hyperthyroidism during pregnancy outweigh the risks if therapy is carefully monitored.
  • Is It Safe To Breastfeed While Im Taking Beta

    Certain beta-blockers are safe to use while youre breastfeeding because only a small amount shows up in breast milk. The lowest possible dose to relieve your symptoms is best. Only a small amount of thyroid hormone medicine reaches your baby through breast milk, so its safe to take while youre breastfeeding. However, in the case of antithyroid drugs, your doctor will most likely limit your dose to no more than 20 milligrams of methimazole or, less commonly, 400 mg of PTU.

    Thyroid Hormones Are Necessary For Normal Fetal Development During The First 3 Months Because Hypothyroidism And Hyperthyroidism Are Possible Thyroid Levels Should Be Monitored Before And Throughout Your Pregnancy

    The thyroid diseaseshyperthyroidism and hypothyroidismare relatively common in pregnancy and important to treat. The thyroid is an organ located in the front of your neck that releases hormones that regulate your metabolism , heart and nervous system, weight, body temperature, and many other processes in the body.

    Thyroid hormones are particularly necessary to assure healthy fetal development of the brain and nervous system during the first three months of your pregnancy since the baby depends on your hormones, which are delivered through the placenta. At around 12 weeks, the thyroid gland in the fetus will begin to produce its own thyroid hormones.

    If you have Grave’s disease while pregnant, you will likely have your thyroid levels checked monthly.

    There are 2 pregnancy-related hormones: estrogen and human chorionic gonadotropin ; that may cause your thyroid levels to rise. This may make it a bit harder to diagnose thyroid diseases that develop during pregnancy. However, your doctor will be on the look-out for symptoms that suggest the need for additional testing.

    Untreated thyroid diseases during pregnancy may lead to premature birth, preeclampsia , miscarriage, and low birth weight among other problems. Therefore, it is important to talk to your doctor if you have had a history of hypothyroidism or hyperthyroidism so you can be monitored before and during your pregnancy, and to be sure that your medication is properly adjusted, if necessary. ;

    If you have hypothyroidism, your doctor may prescribe thyroxine tablets before and after conception to optimise your thyroid hormone levels. This treatment is usually accompanied by regular thyroid function tests to ensure your thyroid level is in the recommended range. If left untreated, low levels of thyroid hormone can cause complications in pregnancy, such as premature birth, low birth weight and miscarriage. It may also affect the intellectual development of your baby.

    If you have hyperthyroidism, your doctor or specialist may prescribe medication to block thyroid hormone production . The most common medicine used for this is called propylthiouracil. Uncontrolled overactive thyroid during pregnancy has been associated with complications such as a higher fetal heart rate , small gestational size, premature birth or stillbirth.

    How Are Thyroid Conditions During Pregnancy Diagnosed

    Health care providers dont usually test your thyroid before or during pregnancy unless youre at high risk of having a thyroid condition or you have signs or symptoms of one. If you have signs or symptoms of a thyroid condition, especially during pregnancy, tell your provider. Signs of a condition are things someone else can see or know about you, like that you have a rash or youre coughing. Symptoms are things you feel yourself that others cant see, like having a sore throat or feeling dizzy. Signs and symptoms of thyroid conditions may appear slowly over time. Many are signs and symptoms of other health conditions, so having one doesnt always mean you have a thyroid problem.

    Your provider gives you a physical exam and a blood test to check for thyroid conditions. The blood test measures the levels of thyroid hormones and thyroid stimulating hormone in your body. TSH is a hormone that tells your thyroid gland to make thyroid hormones. If you think you may have a thyroid condition, ask your provider about testing.
