Thyroid Hormone Levels During Pregnancy
know all about thyroid hormone level during pregnancy, common disorders. Learn to manage and check thyroid levels during pregnancy.
Introduction
Pregnancy is a beautiful journey, but it also brings many changes to your body, including shifts in your thyroid hormone levels. The thyroid, a small butterfly-shaped gland in your neck, plays a crucial role in regulating metabolism, energy, and even your baby’s brain development.
If your thyroid hormone levels are too high or too low during pregnancy, it can affect both you and your baby. However, the good part is that with proper awareness and care, thyroid imbalances can be managed effectively. Let’s understand how thyroid hormones work during pregnancy and what you can do to stay healthy.
Why Are Thyroid Hormones Important in Pregnancy?
Thyroid hormones (T3 and T4) are essential for:
- Your baby’s brain and nervous system development, especially in the first trimester.
- Maintaining your energy levels and metabolism.
- Supporting a healthy pregnancy by regulating heart rate, digestion, and muscle function.
Since your baby relies entirely on your thyroid hormones in early pregnancy, any imbalance can impact their growth and development.
