Hypothyroidism in Pregnancy
WHAT YOU NEED TO KNOW:
Hypothyroidism is a condition that develops when the thyroid gland makes little or no thyroid hormone. Thyroid hormones help control body temperature, heart rate, growth, and how you gain or lose weight.
Call your local emergency number (911 in the US) or have someone call if:
- You faint or have a seizure.
- You have sudden chest pains or trouble breathing, or swelling in your legs, ankles, or feet.
Seek care immediately if:
- Your water breaks, or you are bleeding from your vagina.
- You have diarrhea, tremors, or trouble sleeping.
Call your doctor if:
- You feel your baby is restless and always kicking, or is very still and not moving at all.
- You are losing weight without trying.
- Your signs and symptoms return or become worse.
- You are out of thyroid medicine.
- You have questions or concerns about your condition or care.
- Thyroid medicine will bring your thyroid hormone level back to normal. The dose may be adjusted during your pregnancy. Your thyroid hormone level will be checked regularly to make sure you get the right dose.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
- Get more iodine. The thyroid gland uses iodine to work correctly and to make thyroid hormones. Your healthcare provider may tell you to eat foods that are rich in iodine. He or she will tell you how much of these foods to eat. Milk and seafood are good sources of iodine. You may also need iodine supplements.
- Keep track of your baby's movements. Keep track of how much your baby moves every day. Wait 1 hour after you eat. Write down every movement that you feel from your baby.
- Check your blood pressure and write it down as often as directed. It is important to measure your blood pressure on the same arm and in the same position each time. Keep track of your blood pressure readings, along with the date and time you took them. Take this record with you to your prenatal visits.
- Weigh yourself daily before breakfast after you urinate. More weight gain than recommended during your pregnancy may be a sign of extra fluid in your body. Keep track of your daily weights and take the record with you to your prenatal visits.
Follow up with your healthcare provider as directed:
You may need to return often for blood tests to monitor your thyroid hormone level. This will show if you are getting the right amount of thyroid medicine. Write down your questions so you remember to ask them during your visits.
