How to Control Thyroid During Pregnancy?

Since many of these symptoms closely resemble those of a normal pregnancy, a medical evaluation is essential to identify the underlying cause and its connection to thyroid function.

Diagnosis of Thyroid Disorders During Pregnancy

Thyroid screening becomes an integral part of prenatal care and is crucial for diagnosing thyroid disorders, which helps protect the mother and fetus. Here are the common procedures:

1.Thyroid Stimulating Hormone (TSH) 

This is a first-level evaluation test reflecting thyroid-stimulating hormone levels. The reference range is 0.2–2.5 mU/L in the first trimester and 0.3–3 mU/L afterwards.

2.Free Thyroxine (FT4) Test

This test measures free thyroxine (FT4) levels, typically low in hypothyroidism. It reflects active thyroid hormones crucial for fetal growth and maternal metabolism.

3.Thyroid Antibody Tests (TPOAb and TRAb)

These tests detect thyroid-specific antibodies, marking autoimmune thyroid disorders. They help identify conditions like Hashimoto’s thyroiditis or Graves’ disease, aiding in predicting and managing thyroid diseases during pregnancy.

Diet and Lifestyle Tips to Control Thyroid Hormones During Pregnancy

Maintaining balanced thyroid hormones during pregnancy is essential for both maternal and fetal health. Certain dietary choices and lifestyle changes can play a key role in managing thyroid function effectively.

Nutritional Considerations for Thyroid Health

• Iodine-Rich Foods: Consumption of dairy products, fish, eggs and foods containing iodised salt is encouraged. A prenatal vitamin containing 150 micrograms of iodine may be recommended.
• Magnesium Sources: Spinach, carrots, and mushrooms help produce adequate thyroid hormone and contribute to metabolic activities.
• Protein Intake: Fish, eggs, meat, and poultry strengthen muscles and enhance energy levels in pregnant women.
• Vitamin A Foods: Include eggs, carrots, and pumpkin in the diet, especially as they help with thyroid issues and are important nutrients.

Lifestyle Changes to Support Thyroid Function

• Stress Management: Exercises to reduce stress, such as deep breathing, prenatal yoga, and meditation, can help reduce thyroid impacts.
• Moderate Exercise: Exercise lightly during pregnancy by walking, swimming, or participating in prenatal yoga.
  Caffeine Moderation: Avoid an intake of caffeine products because these will affect the working of the thyroid gland.

Potential Risks and Complications

Thyroid disorders in pregnancy can severely affect the health of the mother with a range of serious manifestations. A study published in the Journal of Clinical Endocrinology & Metabolism found that untreated thyroid disorders can lead to complications such as an increased prevalence of preeclampsia, gestational diabetes, and placental issues like placental abruption.

Low thyroid hormones can hinder the baby’s development, slowing neurological and cognitive growth. Newborns may have low birth weight, increasing their vulnerability to health issues. Cardiac problems, including arrhythmias and heart failure, may also occur. Most notably, untreated thyroid diseases in pregnancy can lead to IQ deficits, affecting the child’s abilities and future development.

Collaborating with Healthcare Providers

Thyroid disorder control during pregnancy requires proper care coordination between the endocrinologists and obstetricians. These specialists manage hormonal changes and any other complications that may arise and affect both the mother and the baby.

Pregnant women need to be on an individualised plan that takes into account the patient’s history of thyroid disease, medication, and changes in hormonal status during pregnancy.

Prevention Strategies for Thyroid Disorders During Pregnancy

To reduce the risk of thyroid issues during pregnancy, consider the following strategies:

• Thyroid function tests should be encouraged early enough in pregnancy so that any problems can be identified early and necessary action can be taken.
• Iodine should be sourced naturally from foods to avoid overdose, which can occur from supplements without a prescription.
• Always check the thyroid hormone levels and then alter the dose of T3/T4 during pregnancy appropriately.
• Concentrate on selenium products, such as dairy products, eggs, and seafood.
• Use stress-reducing strategies like Yoga, meditation or even deep breathing.
• To support thyroid function, avoid pregnancy-related weight gain by maintaining a healthy weight before conception and during pregnancy.

Conclusion

Thyroid disorders, whether existing or newly diagnosed, play a significant role in pregnancy outcomes and maternity experiences. The best course of action for expectant mothers regarding thyroid health is early screening, proper medical checkups, and living a healthy life.
