Pregnancy and thyroid disorders: for professionals 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. 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. We rely on donations to fund our work supporting and informing people living with thyroid disorders.
