An undiagnosed or uncontrolled thyroid condition can make it harder to get pregnant. It can also increase the risk of miscarriage and harm the developing baby. With appropriate management and regular monitoring of thyroid levels, most women can go on to have a successful pregnancy and a healthy baby. It is therefore vital that women are given information and support to reduce these risks and improve outcomes.

To help women access the best care before, during and after pregnancy, the Royal College of Obstetricians and Gynaecologists (RCOG) published its 2025 Green-top guideline on the Management of Thyroid Disorders in Pregnancy.

This is a summary of the key recommendations to help you manage your patients’ thyroid health at this critical time:

• The BTF Thyroid Disorders and Pregnancy Information Prescription is now available in EMIS. The guidance is for women of reproductive age who are on thyroid hormone treatment for primary hypothyroidism. 
• The BTF pocket-sized Thyroid and Pregnancy Alert Card sets out the key messages in respect of pregnancy and thyroid disorders and is ideal to hand out to patients. If you'd like us to send you free copies for your surgeries please contact us.
