A pregnant person looks at a note on their phone with details about their thyroid treatment to share with their medical team.
Writing down your treatment and the date you confirmed the pregnancy can help you share useful information with your prenatal care team.

Should I wait until my next appointment to report that I’m pregnant?

If you have hypothyroidism or hyperthyroidism and have confirmed a pregnancy, promptly inform the professional managing your thyroid disease and your prenatal care team; you do not need to wait until your next scheduled appointment. They can tell you whether an earlier checkup would be appropriate. If you are planning a pregnancy, discuss it in advance so you can receive guidance based on your medical history.

Feeling well does not confirm that your thyroid is still well controlled

Symptoms alone cannot tell you whether your thyroid condition is adequately controlled. During pregnancy, follow-up and, for some people, treatment may need to change. The decision depends on your diagnosis, medical history, test results, and stage of pregnancy.

Why might monitoring change during pregnancy?

Pregnancy can affect monitoring needs. Your medical team will consider your medical history and the treatment you already receive to decide which tests are needed and when to do them. There is no single schedule that works for everyone who is pregnant and has thyroid disease.

Do not stop or adjust your medication on your own

Do not stop or change your thyroid medication without guidance from a medical professional, even if you think pregnancy may affect your treatment. Tell your team which medication you take and mention any recent changes recommended by a professional. If you have questions, consult the professional responsible for your care before making any changes.

What new symptoms should I report?

Mention any new or worsening symptoms, such as persistent palpitations, pronounced tremor, or unusual weakness. These can have different causes and do not, by themselves, confirm a thyroid problem. If they persist, are severe, or concern you, contact your care team for guidance.

What information is helpful for follow-up?

When you contact your team, say when you confirmed the pregnancy, what thyroid diagnosis you have, and what treatment you receive. Mention any recent changes recommended by a professional, new symptoms, and any test results you already have. With this information, your team can decide what follow-up is appropriate.

Not everyone needs the same tests

The type and frequency of monitoring depend on your medical history, symptoms, test results, and stage of pregnancy. Having a known thyroid condition makes it important to report the pregnancy and coordinate follow-up, but it is not enough to determine a universal plan without an individual assessment.

What to do after confirming a pregnancy

Inform the professional managing your thyroid disease and your prenatal care team; share details about your treatment and follow their guidance about tests and appointments. Do not change your medication on your own. If you are planning a pregnancy, ask for guidance to coordinate your care. This content is for educational purposes and does not replace a medical consultation.

When to seek medical care

If symptoms persist, test results are abnormal, or you have questions about medication, arrange an individual assessment. Do not change treatment or doses without medical guidance.

Frequently asked questions

Should I notify my prenatal care team even if I already see an endocrinologist?

Yes. Inform both the professional managing your thyroid disease and your prenatal care team so they can coordinate follow-up based on your medical history and stage of pregnancy.

Do palpitations or tremor mean my thyroid is out of control?

Not necessarily. They can have different causes and do not, by themselves, confirm a thyroid problem. If they are new, persistent, pronounced, or concerning to you, discuss them with your medical team.

Can I change my thyroid medication when I confirm a pregnancy?

Do not stop or change it on your own. Consult the professional responsible for your care, who can assess whether any change is needed based on your diagnosis, test results, and clinical situation.
