Can a woman with thyroid problems get pregnant? HealthifyMe

If you are currently being treated for a thyroid condition or have had thyroid problems in the past, it is important to know what to expect when trying to get pregnant.

The thyroid gland plays an important role in overall reproductive health, including fertility, so an undiagnosed thyroid condition can make it difficult to conceive. However, a healthy and successful pregnancy is possible only when thyroid function is restored or thyroid disease is under control.

Thyroid and Pregnancy: The Connection

If you have hyperthyroidism:

Hyperthyroidism is a case of an overactive thyroid that causes light and irregular periods. The increased levels of thyroid hormones caused by hyperthyroidism disrupt your menstrual cycle, making it more difficult to get pregnant. If you have active hyperthyroidism, you must take antithyroid medications and a preventive diet during pregnancy.

If you are trying to get pregnant after treatment, you should get your thyroid checked through a blood test. This is because you may still have Graves’ antibodies in your blood, which may affect your chances of conception.

Also, women who previously had hyperthyroidism but did not receive thyroid surgery or radioiodine may have a relapse. Therefore, working with your doctor to achieve a stable balance is essential.

If you have hypothyroidism:

If you have untreated or treated hypothyroidism, there is a high chance that you will have difficulty conceiving. Women with hypothyroidism may have heavy or heavy periods, which can lead to anemia.

Sometimes, periods may stop completely. However, taking medication (levothyroxine pills) and getting your thyroid back to normal can dramatically improve your chances of getting pregnant.

If you have postpartum thyroiditis:

Postpartum thyroiditis is an inflammatory thyroid disorder that occurs in 5–10% of women after childbirth. It is most common in women with thyroid auto-antibodies.

Postpartum thyroiditis is usually a temporary disorder. It may get better after a few months with or without treatment with levothyroxine tablets. However, postpartum thyroiditis can sometimes lead to hypothyroidism, which makes it difficult to conceive in the future.

Therefore, it is important to get thyroid function tests done before you conceive and after each birth. There is a 50% risk of recurrence of postpartum thyroiditis in subsequent pregnancies.

Can a woman get pregnant with a thyroid condition?

You can still get pregnant with hyperthyroidism or hypothyroidism, but getting pregnant can be more challenging. Additionally, if you have a thyroid disorder during pregnancy, your baby may have an increased risk of low birth weight, rapid heart rate, poor weight gain, and low IQ. Hence, it is safe to plan your pregnancy after getting your thyroid hormone levels under control.

If you’ve already been diagnosed with a thyroid condition, you’re at a significant advantage compared to those who are undiagnosed. Treating your thyroid condition before trying to get pregnant can help reduce your chances of miscarriage and other fertility problems. For example, a study found that 76% of 400 women diagnosed with hypothyroidism could conceive within a year of treatment.

HealthifyMe Note

While you can get pregnant with a thyroid condition, any disruption to normal thyroid function can lead to delayed conception. Additionally, a pregnancy with thyroid problems can increase the health complications of your baby. Therefore, doctors strongly recommend that you first get your thyroid hormone levels under control and then plan for pregnancy.

What to do and know during pregnancy?

Here’s what you can expect after becoming pregnant if you suffer from a thyroid condition.

According to ResearchPremature birth, preeclampsia, poor fetal growth and brain development, low birth weight, and miscarriage can occur if you don’t address thyroid disease with medication during pregnancy.

Consider taking anti-thyroid medications to help reduce abnormal levels of thyroid hormone. Never stop taking a thyroid supplement without talking to your doctor, especially while pregnant.

All pregnant women with thyroid dysfunction should be screened for abnormal TSH (thyroid stimulating hormone) levels. TSH should be less than 2.5 mIU/mL in the first trimester. It may sound overwhelming, but thyroid monitoring during pregnancy will pay off.

Keep track of your iodine intake before pregnancy and during pregnancy. During pregnancy, you’ll need extra iodine — about 250 micrograms each day. Iodized salt, dairy products for vegetarians legumesWhole grains, kale, strawberries, meat, poultry and seafood are excellent sources of iodine.

Prenatal vitamins are an essential component of preconception and pregnancy nutrition. However, it is important to discuss with your health professional whether a prenatal vitamin containing iodine is appropriate for you.


Getting pregnant can be more challenging if you have a thyroid condition, but it’s not impossible. All women thinking of becoming pregnant and having a thyroid condition should get treated.

Thyroid conditions during pregnancy can increase the risk of complications for the mother and baby. Fertility issues will go away with proper treatment for your thyroid condition. However, remember that each case is different, so you should work with a specialist to develop a treatment plan that’s right for you.
