Your Thyroid While Youre Pregnant

Getting PREGNANT with a THYROID gland disorder

There are a few ways pregnancy can be impacted if thyroid problems arent addressed first.

Increasing demands from a developing baby can occasionally cause new onset or worsening hypothyroidism for pregnant women.

Additionally, impaired thyroid function prior to and during conception can impact healthy brain development in the fetus. That said, T4 therapy through meds like levothyroxine can of babies born with a lower body weight and other complications.

As for pregnancy loss and miscarriage, theres been little evidence found to directly link hyperthyroidism to either. But one study did find that the risk of miscarriage is doubled with hyperthyroid women as compared to women without thyroid issues. In terms of hypothyroidism , there is evidence that suggests that inadequate treatment can lead to infertility, miscarriage, and adverse pregnancy outcomes.

After pregnancy, theres also an increased risk for postpartum thyroiditis, or inflammation of the thyroid this happens to five to ten out of every 100 women within the first year after childbirth. This can lead to temporary hypothyroidism, hyperthyroidism, or hyperthyroidism followed by hypothyroidism.

Thyroid Dysfunction And Reproductive Health

Thyroid function is regulated by the hypothalamus-pituitary axis , an interconnected duo made up of the hypothalamus and the pituitary gland . This pair is as thick as thieves when one of these organs sends a signal, it sets off a chain reaction in the other.

Because the HPA also controls the production of some of the most important hormones related to fertility, thyroid dysfunction can impact how much of those hormones are released. When any of these deviations from the status quo happen, they can disrupt menstrual cycles. Without the complete cycle, including ovulation, fertilization, and implantation, you cant get pregnant naturally.

As a result of these hormone changes, both hyperthyroidism and hypothyroidism have been linked to abnormal menstrual cycles.

All that said, getting a handle on your thyroid through treatment can reduce the chances of related fertility issues down the line. In one study of a group of almost 400 women suffering from infertility, 24% of participants were found to have hypothyroidism but within a year of treatment, 76% were able to conceive.

How Is Graves’ Disease Treated

Treatments for Graves’ disease lower the amount of thyroid hormone in your body or block the action of thyroid hormone. There are three main treatments for Graves’ disease:

  • Antithyroid medicine. The Food and Drug Administration has approved two medicines for Graves’ disease: , or MMI and , or PTU. These medicines keep the thyroid gland from making too much thyroid hormone. They are often given to patients before thyroid surgery or radioiodine therapy. You cannot take MMI in the early stages of pregnancy, because it may hurt your developing baby.
  • Radioactive iodine . RAI is a type of iodine that damages the thyroid gland by giving it radiation. The RAI destroys thyroid cells so that your thyroid gland cannot make as much thyroid hormone. This cures the overactive thyroid gland, but it can lead to underactive thyroid gland. If this happens, you will need to take thyroid hormone for the rest of your life.
  • Surgery to remove all or most of the thyroid. As with RAI, surgery cures overactive thyroid but can lead to underactive thyroid. You will need to take thyroid hormone to replace the needed thyroid hormone that your body can no longer make.

All medicines have risks. You should talk to your doctor about the benefits and risks of all medicines.

Can Hypothyroidism Impact Your Fertility

An underactive thyroid can affect your ability to conceive. Heres what to do if you have hypothyroidism and are trying to become pregnant.


When your thyroid gland isnt making enough thyroid hormone, it can have a serious effect on every organ in your body including your reproductive system.

This means hypothyroidism may make it difficult to conceive if youre planning on having children. A study published in August 2015 in the Journal of Pregnancy found that women with hypothyroidism were less likely to become pregnant and more likely to take longer to become pregnant than women without the condition.

Thats because women with hypothyroidism may not ovulate or ovulate with any regularity, and you have to ovulate to get pregnant, says Ingrid Rodi, MD, a gynecologist and reproductive endocrinologist at UCLA Medical Center in Santa Monica, California.

Hypothyroidism can affect fertility in men as well, according to the Thyroid Foundation of Canada. Although hypothyroidism is less common in men, those who do have an underactive thyroid may have low libido and low sperm count, according to a review of research published in November 2013 in Frontiers in Endocrinology in November 2013.

Additionally, hypothyroidism can lead to fatigue in both men and women. When youre fatigued, you may not have much sex, Dr. Rodi says. Its harder to get pregnant when youre not having much sex.

Its a little gland in your neck shaped like a butterfly, but the thyroid is powerful. It regulates everything from body temperature to metabolism, but most of us never think about our thyroid until something goes wrong.

How Is Hypothyroidism Tested

The main test used to detect hypothyroidism is measuring blood levels of TSH. An elevated TSH level usually means the thyroid gland is not making enough thyroid hormone, and the pituitary gland has responded by making more TSH to try to get the thyroid hormone levels where they should be.

Other blood tests include measuring T4 and thyroid autoantibodies. Antibodies are substances made by your immune system, usually to protect you against bacterial and viral infections. Sometimes, however, the immune system can make antibodies against your own bodysuch as against your thyroid. T4 is a hormone produced directly by the thyroid gland. It is typically low in patients with hypothyroidism. An autoantibody is an antibody that attacks the cells and tissues of the organism that made it. Thyroid autoantibodies are seen in patients with Hashimotos thyroiditis.

How Do Doctors Treat Hypothyroidism During Pregnancy

Treatment for hypothyroidism involves replacing the hormone that your own thyroid can no longer make. Your doctor will most likely prescribe levothyroxine, a thyroid hormone medicine that is the same as T4, one of the hormones the thyroid normally makes. Levothyroxine is safe for your baby and especially important until your baby can make his or her own thyroid hormone.

Your thyroid makes a second type of hormone, T3. Early in pregnancy, T3 cant enter your babys brain like T4 can. Instead, any T3 that your babys brain needs is made from T4. T3 is included in a lot of thyroid medicines made with animal thyroid, such as Armour Thyroid, but is not useful for your babys brain development. These medicines contain too much T3 and not enough T4, and should not be used during pregnancy. Experts recommend only using levothyroxine while youre pregnant.

Some women with subclinical hypothyroidisma mild form of the disease with no clear symptomsmay not need treatment.

If you had hypothyroidism before you became pregnant and are taking levothyroxine, you will probably need to increase your dose. Most thyroid specialists recommend taking two extra doses of thyroid medicine per week, starting right away. Contact your doctor as soon as you know youre pregnant.

Your doctor will most likely test your thyroid hormone levels every 4 to 6 weeks for the first half of your pregnancy, and at least once after 30 weeks.1 You may need to adjust your dose a few times.
