Pregnancy is a beautiful chapter in a woman’s life, but it also brings specific physical and psychological changes that support the baby’s growth. However, when the thyroid gland (a small butterfly-shaped gland in your neck) produces too much (Hyperthyroidism) or too little hormone (Hypothyroidism), it may affect you and your baby’s health.
Imbalanced thyroid levels may cause pregnancy complications such as miscarriage, preterm delivery, or developmental delays in the baby. Thus, regular monitoring is crucial to maintain balanced thyroid levels during pregnancy. Let’s understand the symptoms, diagnosis, treatment, and proper timing for thyroid hormone screening.

Common Symptoms of Thyroid Problems in Pregnancy

While some thyroid symptoms resemble typical pregnancy signs, severe cases require further medical evaluation. Here are the common symptoms of thyroid issues (of both types) in pregnancy.

Symptoms of Hypothyroidism

● Dry skin & hair loss
● Weakness or unusual fatigue
● Constipation
● Excessive weight gain
● Swelling in the neck
● Sensitivity to cold

Symptoms of Hyperthyroidism

● Unnatural weight loss
● Rapid heartbeat or palpitations
● Excessive sweating
● Nervousness
● Swelling at the base of the neck
● Trouble sleeping

When to Get Tested for Thyroid Disorders?

Doctors usually recommend a thyroid function test once every trimester or more if needed. Though routine thyroid testing isn’t always a part of prenatal screening, your healthcare professional may recommend it if you have risk factors such as:
● Family history of thyroid disorders
● Previous miscarriage or preterm birth
● History of thyroid surgery
● Type 1 diabetes or other autoimmune conditions
● Excessive weight loss, weight gain

Safe Treatment Options for Balanced Thyroid Health During Pregnancy

Managing thyroid levels is crucial for both the mother’s and the baby’s well-being. Regular monitoring and doctor-suggested tips may help balance the thyroid levels and lead to a healthy, safe pregnancy. Here are the treatment tips for balanced thyroid health.

1. Medications Under Doctor’s Supervision

The first step to balancing thyroid health during pregnancy is to take the doctor’s prescribed medicines. In case of hypothyroidism, your doctor will recommend medications that restore normal hormone levels, improve metabolism, and support the baby’s brain development. On the other hand, if you’re suffering from hyperthyroidism, your doctor will recommend medicines that control excessive hormone production.
Note: Consume the prescribed dosage. Do not stop taking the medicine abruptly; stick to your doctor’s advice. In case of unusual side effects, get immediate medical assistance.

2. Dosage Adjustments are Important

During pregnancy, thyroid hormones requirement increase by 30 to 50 percent, so regular monitoring is crucial to keep them within a normal range. If you are on treatment for hyperthyroidism, a medication change would be required during pregnancy. Doctors usually recommend thyroid tests every 4 to 6 weeks, or more frequently if needed, depending on your condition. These regular check-ups are essential for monitoring your thyroid levels and adjusting doses accordingly.

Tip: Don’t adjust the dosage yourself. Your doctor will manage the doses based on your current medical reports and overall health.

3. Don’t Overlook Nutrition

Consuming a nutritious diet is crucial to maintaining thyroid function during pregnancy. Iodine is essential for thyroid hormone production. Adding iodine-rich foods to your diet supports hormone synthesis and immune function. Furthermore, stay hydrated, get adequate sleep, and manage stress through prenatal yoga or breathing exercises to support overall hormonal balance.

Tip: Avoiding Brasssica group of vegetables (Ex: cabbage, cauliflower, Broccoli etc), milk, soya or Wheat and consuming Brazilian nuts do not have a significant impact on Thyroid health.

4. Postpartum Thyroid Care

After childbirth, thyroid hormone requirements might change again due to reduced requirement or postpartum thyroiditis. Regular follow-ups are vital to monitor thyroid function. Remember that making a timely adjustment is essential for both the mother’s and the baby’s well-being, especially during breastfeeding.

Thyroid problems are common in pregnancy, but early diagnosis, regular monitoring, and the doctor’s medications can easily manage them. Whether you have hyperthyroidism or hypothyroidism, implementing the right tips, such as taking the doctor’s prescribed medications, sticking to a balanced diet, and a proper sleep schedule, combined with postpartum thyroid care, may help lead to a safe, healthy pregnancy.
