Pregnancy Pregnancy and thyroid disorders An undiagnosed or uncontrolled thyroid disorder can make it harder to conceive and can cause problems during pregnancy. We have guidance to help patients understand more about their thyroid disorder and how it may affect, or be affected by, pregnancy. If you've been diagnosed with a thyroid disorder, you should let your doctor know that you're trying for a baby because they may need to make changes to your medication. If you're pregnant or want to get pregnant and you have thyroid disease or a history of thyroid disease in your family, please see the information on the following links: Pregnancy and thyroid disorders guidance Thyroid disorders in pregnancy article Pregnancy and thyroid disorders alert card Thyroid and pregnancy FAQs Breastfeeding and thyroid disease Read our pregnancy webinar Q&As Thyroid disorders and getting pregnant short film - shared with kind permission of Concise Medical Information Cines (CoMICs) Pregnancy and hypothyroidism short film - shared with kind permission of Concise Medical Information Cines (CoMICs) Pregnancy and hyperthyroidism short film - shared with kind permission of Concise Medical Information Cines (CoMICs) Information for healthcare professionals Please help us help others With your support we can help people to live better with thyroid disease.
