Thyroid disease and pregnancy: an overactive or underactive thyroid, the medicines, and after the baby

For anyone pregnant, or hoping to be, with a thyroid problem, anyone who had Graves’ disease or Hashimoto’s disease, and anyone whose moods, sleep or heartbeat changed after a baby was born. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK, part of the NIH) says that with thyroid problems you can still have a healthy pregnancy and protect your baby’s health, with regular thyroid tests and the medicines your doctor prescribes. This page passes on, by name, what NIDDK says: why the thyroid matters for the baby, and the signs; an overactive thyroid and Graves’ disease, and the medicines used in pregnancy; an underactive thyroid and levothyroxine; and after the baby: postpartum thyroiditis, breastfeeding, and iodine. It builds the words to say and the questions to ask, and prints a card to keep with you.

Right now

  • Chest pain, trouble breathing, fainting, or a seizure? Call 911 (ours). Something feels wrong with the pregnancy? Call your doctor or midwife now (ours).
  • On an antithyroid medicine, with yellow skin or eyes, a dull belly pain, a sore throat that will not go away, or a fever? NIDDK says stop the medicine and call your doctor right away; if you do not hear back the same day, go to the nearest emergency room.
  • Just found out you are pregnant, and you take levothyroxine? NIDDK says contact your doctor as soon as you know: you will probably need a higher dose.
  • Worn down, or thinking of ending your life? Call or text 988, any hour (ours).

Other guides on this site that go with this page

Free to read. We chose these ourselves; no professional did. Each guide was written with AI and has not been reviewed by a professional. They are general information, not advice.

General information from people who care, not medical advice. We are not doctors, nurses or midwives. Only your health care team can say how your thyroid is working, which medicine and dose are right during the pregnancy and after, and how often to test, and this page cannot. Follow the instructions your team gives you over anything here. This guide names only the medicines NIDDK names, and no brand or dose. In an emergency, call 911.

This page and its wording were written with AI (Claude) for Scarlet Beast (our AI policy). No doctor, nurse or midwife has reviewed it. The facts were read on October 18, 2026 on NIDDK’s (NIH) page Thyroid Disease & Pregnancy (last reviewed December 2017), in English and in Spanish. That page is not new, and your team may know newer advice. The numbers (the first 3 months; around 12 weeks; 18 to 20 weeks; 1 to 4 of every 1,000 pregnancies; 2 to 3 of every 100; every 4 to 6 weeks, and once after 30 weeks; about 1 in 20; up to 3 months; up to a year; about 250 micrograms of iodine a day; 150 micrograms in a prenatal vitamin) are NIDDK’s. Ours: 911 for chest pain, trouble breathing, fainting or a seizure; calling your doctor or midwife now if something feels wrong with the pregnancy; telling your team about any thyroid problem you have had; never stopping or changing a prescribed medicine on your own, apart from NIDDK’s stop-and-call list; the after-hours number on your card; 988 and the maternal mental health line; and the order of the steps. What we left out: the brand NIDDK names, the dose changes and the breastfeeding dose limits NIDDK gives (only your doctor can set your dose), the references, the clinical-trials section, and NIDDK’s outside links. This page saves nothing and loads no trackers.
