Thyroid disease refers to conditions where the thyroid gland doesn't function properly, like producing too much or too little thyroid hormone. Thyroid health is especially important during pregnancy because these hormones play a key role in the healthy development of the baby's brain and nervous system. Untreated thyroid issues can also lead to complications for both mom and baby, including miscarriage and growth problems.

Pregnancy brings many changes, including to your thyroid. Your body might need more thyroid hormones because of increased demand from you and your growing baby. Pregnancy hormones can also cause your thyroid size to slightly increase. It's a bit like your body's way of adapting to ensure your baby gets everything it needs.

Not everyone needs screening, but if you are at high risk, like if you have a history of thyroid problems, type 1 diabetes, or other specific health conditions," it is a smart move.

Treatment depends on whether you have hypothyroidism (too little hormone) or hyperthyroidism (too much hormone). For hypothyroidism, levothyroxine, a synthetic thyroid hormone, is often prescribed to keep hormone levels in check. For hyperthyroidism, the treatment plan might include antithyroid medications. It's all about keeping you and your baby safe, so your doctor will guide you through the best treatment plan.

Yes, it can. Thyroid hormones are superstars in your baby's brain and nervous system development, especially in the first trimester, when the baby relies entirely on your thyroid hormone supply. If your thyroid levels are unbalanced, it could impact your baby's growth and brain development. That's why managing thyroid conditions during pregnancy is so important.

Checking your thyroid levels first is a good idea if you're planning a pregnancy. Being in a euthyroid state (having normal thyroid function) can improve your chances of a successful pregnancy and reduce the risk of miscarriage. Also, inform your doctor immediately when you're pregnant so they can adjust your treatment plan. Regular check-ups will be key to keeping you and your baby healthy.
