The Need For Thyroid Replacement During Pregnancy

What is it?

Thyroid replacement during pregnancy is when a pregnant woman takes supplement hormones to replace the ones that her thyroid has stopped making. The purpose of this is to help her body produce the necessary hormones to support a healthy pregnancy.

Why is it important?

Thyroid hormones play an important role in the regulation of key functions in the body, including heart rate, body metabolism, digestive functions, and temperature regulation. During pregnancy, these hormones are essential for healthy fetal development. They help to:

  • prepare the uterus for implantation of the embryo
  • promote proper brain development in the fetus

  • ensure normal bone, muscle, and organ development
  • provide nutrition to the developing fetus

Without the necessary amounts of thyroid hormones, pregnant women may experience a range of health issues, including preterm labor, miscarriage, and fetal death.

Who is at risk?

Women who are pregnant or planning to become pregnant may be at risk for developing hypothyroidism. This is a condition in which the thyroid does not produce enough thyroid hormones for the body’s needs. It is important for pregnant women to be checked for hypothyroidism as soon as possible in order to ensure their fetus is getting the necessary nutrition for proper development.

How do I get replacement hormones?

If it is determined that you are at risk for hypothyroidism, your doctor will likely recommend that you take a daily thyroid hormone supplement. This will help to increase the amount of hormones in your body so that your fetus can receive adequate hormones for proper development.

What are the side effects?

The most common side effects of taking a daily thyroid hormone supplement are:

  • anxiety
  • nervousness
  • insomnia
  • headache
  • excessive sweating
  • palpitations
  • loss of appetite
  • weight gain

It is important to talk to your doctor about any side effects that you are experiencing so that your dosages can be adjusted accordingly.


It is essential for pregnant women to have adequate thyroid hormone levels throughout their pregnancy in order to ensure a healthy pregnancy and fetus. If you are pregnant or planning to become pregnant, talk to your doctor about getting screened for hypothyroidism and receiving the necessary thyroid hormone therapy to ensure your body and your fetus are receiving the necessary nutrition for a successful pregnancy.
