Pregnant women 'must manage thyroid hormone levels'

All pregnant women should take a daily prenatal vitamin with iodine in the form of potassium iodide, the American Thyroid Association (ATA) has claimed.

The association claims that hypothyroidism – where not enough of the thyroid hormone is produced – can lead to increased risks of complications such as miscarriage and early delivery.

It is claimed that for the first ten to 12 weeks of pregnancy, the developing baby is completely dependent on its mother for the production of this hormone.

ATA says the baby's thyroid only begins to produce the hormone at the end of the first trimester of pregnancy.

It remains dependent on the mother to ingest adequate amounts of iodine during pregnancy, something that is essential for hormone generation, the association claims.

This intake is vital for the normal development of the fetal brain, ATA says.

One of the largest endocrine glands in the human body, the thyroid is located in the middle of the lower neck.ADNFCR-2094-ID-19064463-ADNFCR
