Introduction
Thyroid disorders are common during pregnancy and can significantly impact both the mother and baby if left untreated. Proper diagnosis and timely management are essential for a healthy pregnancy. At Shukan Hospital & IVF Center, we specialize in diagnosing and treating thyroid disorders in expectant mothers, ensuring a smooth pregnancy journey.
Understanding the Thyroid Gland and Pregnancy
The thyroid gland, located in the neck, produces hormones (T3 and T4) that regulate metabolism, energy levels, and overall bodily functions. During pregnancy, the body’s demand for thyroid hormones increases to support fetal development, making thyroid disorders more prevalent.
Normal Thyroid Hormone Levels
For Non-Pregnant Adults:
- TSH (Thyroid-Stimulating Hormone): 0.4 – 4.0 mIU/L
- Free T4: 0.8 – 2.0 ng/dL
For Pregnant Women:
- First Trimester: TSH: 0.1 – 2.5 mIU/L | Free T4: 0.8 – 1.5 ng/dL
- Second Trimester: TSH: 0.2 – 3.0 mIU/L | Free T4: 0.7 – 1.8 ng/dL
- Third Trimester: TSH: 0.3 – 3.5 mIU/L | Free T4: 0.7 – 1.8 ng/dL
Common Thyroid Disorders in Pregnancy
1. Hypothyroidism (Underactive Thyroid)
- Occurs when the thyroid gland does not produce enough hormones.
- Most commonly caused by Hashimoto’s thyroiditis (an autoimmune condition).
Symptoms:
- Fatigue and excessive weight gain.
- Dry skin and hair loss.
- Depression and mood swings.
- Constipation.
- Slow heart rate.
Diagnosis:
- Blood tests measuring TSH (Thyroid-Stimulating Hormone) and Free T4.
- TPO (Thyroid Peroxidase) antibodies test for autoimmune thyroid disorders.
Treatment:
- Levothyroxine (Synthroid) is the standard treatment.
- Regular TSH monitoring is required for dose adjustments.
Risks if Left Untreated:
- Increased risk of miscarriage and preterm birth.
- Developmental delays in the baby.
- Maternal preeclampsia and anemia.
2. Hyperthyroidism (Overactive Thyroid)
- Occurs when the thyroid produces excess hormones.
- Graves’ disease (an autoimmune disorder) is the most common cause.
Symptoms:
- Unexplained weight loss.
- Rapid heartbeat and high blood pressure.
- Excessive sweating and heat intolerance.
- Nervousness and irritability.
- Tremors (shaky hands).
Diagnosis:
- Blood tests measuring low TSH and high Free T4/T3.
- Thyroid ultrasound to check for nodules.
- Thyroid-stimulating immunoglobulin (TSI) test for Graves’ disease.
Treatment:
- Antithyroid medications (PTU or Methimazole).
- Beta-blockers for heart rate control.
- Surgery (thyroidectomy) in severe cases.
Risks if Left Untreated:
- Increased risk of preeclampsia and stillbirth.
- Low birth weight and fetal growth restriction.
- Neonatal hyperthyroidism in newborns.
3. Postpartum Thyroiditis
- Inflammation of the thyroid after childbirth.
- May cause temporary hyperthyroidism, followed by hypothyroidism.
Symptoms:
- Fatigue and depression.
- Weight fluctuations.
- Heart palpitations.
Treatment:
- Symptoms often resolve naturally.
- Beta-blockers for symptom relief.
- Thyroid hormone replacement if hypothyroidism persists.
Nutritional Needs for Thyroid Health in Pregnancy
Proper diet and nutrition play a key role in managing thyroid disorders during pregnancy. At Shukan Hospital, we emphasize a balanced diet rich in essential nutrients:
1. Iodine:
- Essential for thyroid hormone production.
- Recommended Daily Allowance (RDA): 220 mcg/day during pregnancy.
- Found in iodized salt, dairy products, eggs, and seafood.
2. Selenium:
- Supports thyroid function and reduces inflammation.
- RDA: 60 mcg/day.
- Found in brazil nuts, fish, and whole grains.
3. Iron:
- Helps with thyroid hormone synthesis and prevents anemia.
- RDA: 27 mg/day.
- Found in spinach, legumes, red meat, and fortified cereals.
4. Vitamin D:
- Improves immune function and reduces thyroid inflammation.
- RDA: 600 IU/day.
- Found in sunlight, dairy products, and fish.
5. Omega-3 Fatty Acids:
- Supports fetal brain development and reduces inflammation.
- Found in salmon, flaxseeds, and walnuts.
