Why do doctors ask for the Thyroid test after a miscarriage?

Thyroid hormone controls our body's metabolic process. Hypothyroidism is a condition which means that the thyroid gland is not producing enough thyroid, due to which there can be many implications for anyone and especially it matters a lot for a pregnant lady.

Your thyroid hormones are as crucial for your baby as they are for you. During the first 3 months of the pregnancy, baby depends on your supply of thyroid hormone through the placenta. The baby's overall development and development of the baby’s brain and nervous system depends on the supply of thyroid hormone from the mother. At around 12 weeks, your baby’s thyroid starts to work on its own, but it doesn’t make enough thyroid hormone until 18 to 20 weeks of pregnancy.

Women with less thyroid production have the risk of miscarriage, because of deficiency of thyroid hormones which are essential for the growth and metabolism of the growing fetus.
