Hypothyroidism in Pregnancy
WHAT YOU NEED TO KNOW:
What is hypothyroidism?
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.
What increases my risk for hypothyroidism?
- Autoimmune disease, such as Hashimoto's disease
- Radiation therapy or thyroid surgery
- History of hypothyroidism, thyroid cancer, or an enlarged thyroid
- Family history of hypothyroidism or an autoimmune disease
- Low iodine level
What are the signs and symptoms of hypothyroidism during pregnancy?
- Extreme fatigue
- Sensitivity to cold
- Dry, flaky skin, or brittle fingernails
- Thin hair
- Muscle pain or weakness
- Swollen thyroid gland
- Depression or irritability
How is hypothyroidism diagnosed?
Your healthcare provider will ask about your symptoms and examine you. He or she will ask what medicines you take. Tell him or her about your medical history and if anyone in your family has hypothyroidism. You will have blood tests to check your thyroid hormone level.
How is hypothyroidism treated?
Thyroid medicine will bring your thyroid hormone level back to normal. You may also need iodine supplements or eat foods higher in iodine. Ask your healthcare provider for more information on other medicines you may need.
How can I manage my condition?
- 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.
- Keep track of your blood pressure and weight:
- 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. Weight gain 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.
Call your local emergency number (911 in the US) if:
- You faint or have a seizure.
- You have sudden chest pains or trouble breathing, or swelling in your legs, ankles, or feet.
When should I call my doctor?
- You have diarrhea, tremors, or trouble sleeping.
- You feel your baby is restless and always kicking, or is very still and not moving at all.
- Your water breaks, or you are bleeding from your vagina.
- 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.
