Pregnancy brings so many changes to your body, and your thyroid—that small butterfly-shaped gland in your neck—works harder than ever during these nine months. If you’re wondering how to care for your thyroid during pregnancy, you’re already taking an important step toward a healthy journey for both you and your baby.
Your thyroid produces hormones that help your baby’s brain develop properly. It also controls your energy levels, body temperature, and metabolism. During pregnancy, your body needs up to 50% more thyroid hormones. This means even women who’ve never had thyroid problems before might face challenges.
Whether you have hypothyroidism, hyperthyroidism, or simply want to keep your thyroid healthy, understanding the basics can make a real difference. Let’s walk through everything you need to know about thyroid care during pregnancy.
Why Your Thyroid Health Matters During Pregnancy
Your thyroid does crucial work when you’re expecting. The hormones it produces—called T3 and T4—help build your baby’s brain and nervous system, especially in the first trimester. Without enough thyroid hormone, your baby’s development could be affected.
Pregnancy naturally changes how your thyroid works. The pregnancy hormone hCG actually stimulates your thyroid to work harder. Your body also produces more blood, which dilutes thyroid hormones. These changes mean you need closer monitoring throughout pregnancy, even if your thyroid was perfectly healthy before.
Common Thyroid Problems You Might Face
▹Hypothyroidism (Underactive Thyroid)
This happens when your thyroid doesn’t make enough hormones. You might feel constantly tired (more than typical pregnancy fatigue), gain weight unexpectedly, feel unusually cold, or struggle with brain fog. Some women also experience constipation or notice their hair becoming dry and brittle.
If left untreated, hypothyroidism can lead to serious issues like miscarriage, preeclampsia, or problems with your baby’s brain development.
▹Hyperthyroidism (Overactive Thyroid)
This is when your thyroid makes too much hormone. Signs include a racing heartbeat, feeling overheated all the time, unexplained weight loss, shaky hands, and severe anxiety. Untreated hyperthyroidism might cause premature birth or low birth weight.
The tricky part? Many thyroid symptoms look like normal pregnancy experiences. That’s why testing is so important.
Recognizing Warning Signs
Pay attention to these symptoms and mention them to your doctor:
For Hypothyroidism:
- Exhaustion that rest doesn’t fix
- Unexpected weight gain beyond normal pregnancy
- Difficulty concentrating or remembering things
- Always feeling cold when others are comfortable
- Very dry skin or hair loss
For Hyperthyroidism:
- Heart racing or pounding
- Constant sweating or feeling too hot
- Losing weight despite eating enough
- Trembling hands
- Extreme nervousness or irritability
Essential Steps for Thyroid Care During Pregnancy
▹Get Tested Early and Regularly
Ask for thyroid screening before you conceive or during your first trimester. The tests check your TSH (thyroid stimulating hormone), Free T4, and sometimes thyroid antibodies. If you have thyroid issues, expect testing every 4-6 weeks throughout pregnancy. Your doctor will tell you what your numbers should be, as pregnancy requires different target levels than normal.
▹Take Medication as Prescribed
If you need thyroid medication, take it every single day—usually first thing in the morning on an empty stomach.
Many women need higher doses during pregnancy, which is completely normal. Never adjust your dose or skip pills without talking to your doctor.
Important tip: Wait at least 3-4 hours after taking thyroid medication before taking calcium supplements, iron, or prenatal vitamins. These can interfere with how your body absorbs the medication.
▹Eat Foods That Support Your Thyroid
Focus on getting enough iodine through iodized salt, dairy products, eggs, and safe seafood options. Brazil nuts, fish, and whole grains provide selenium, which your thyroid needs. Include iron-rich foods like lean meats, beans, and fortified cereals.
You don’t need to avoid foods, but be mindful of timing. Take your thyroid medication away from high-calcium foods and soy products. Large amounts of raw broccoli, cauliflower, or kale might interfere with thyroid function, but cooked vegetables in normal portions are perfectly fine.
▹Choose the Right Prenatal Vitamin
Look for a prenatal vitamin with about 150 mcg of iodine. Most women get what they need from a good prenatal and a balanced diet. Don’t add extra iodine supplements without asking your doctor—too much can actually harm your thyroid.
▹Manage Stress Levels
Stress affects your thyroid hormones. Try gentle activities like prenatal yoga, meditation, or simply taking walks. Get enough sleep—your thyroid needs rest to function properly. Build a support system of friends, family, or support groups who understand what you’re going through.
▹Stay Active Safely
Moderate exercise helps your thyroid work better and boosts your energy. Walking, swimming, and prenatal yoga are great choices. Listen to your body—if you’re exhausted, take it easy. The goal is gentle movement, not pushing yourself hard.
▹Keep Your Doctor Informed
Stay in regular contact with your doctor about any symptoms or concerns. If you have thyroid problems, you might benefit from seeing both your pregnancy doctor and a thyroid specialist. Keep notes about how you’re feeling, which helps your doctor make better decisions about your care.
After Your Baby Arrives
Your thyroid needs attention after delivery too. Some women develop postpartum thyroiditis, which can cause thyroid levels to swing up and down. Continue monitoring your thyroid in the months after birth.
If you’re breastfeeding, thyroid medications are safe to take. You’ll still need regular blood tests to make sure your dose is right. Many women need dose adjustments after delivery as their body returns to its pre-pregnancy state.
When to Seek Medical Help
Contact your doctor if you experience:
- Severe fatigue that doesn’t improve with rest
- Rapid heartbeat or chest pain
- Sudden weight changes
- Extreme mood swings or depression
- Difficulty breathing or swallowing
- Visible swelling in your neck
