Thyroid disorders during pregnancy can lead to complications such as preeclampsia, premature birth, low birth weight, miscarriage, and stillbirth. Pregnant women should regularly monitor their thyroid hormone levels and seek timely intervention when necessary. Treatment aims to promote hormonal balance and support a healthy pregnancy. Maintaining a healthy lifestyle, eating iodine-rich foods, and following a well-balanced diet are also important. Medication may be prescribed by a doctor to normalize thyroid hormone levels.
