The ATF recommend all women of childbearing age should be aware of their thyroid function levels, family thyroid history and daily iodine intake. Thyroid function (TSH level) and auto-immune disease testing (thyroid auto antibodies TPO & TGO) are recommended to rule out a thyroid disorder during this life stage. This testing is best done as early as possible in pregnancy or prior to conception if there is any suspicion or concern about a thyroid disorder. If necessary a thyroid ultrasound can be ordered to determine any physical abnormalities of the thyroid gland. 

Australian research states 50% of pregnancy and breastfeeding women are mildly to moderately iodine deficient. An adequate daily intake of iodine enriched foods with a Pregnancy Supplement including at least 150 mcgs of iodine is recommended. The iodine supplement should be continued while breastfeeding.

If you are considering pregnancy, or if you are pregnant or breastfeeding, it is important your thyroid function is tested, monitored and treated if necessary. A daily adequate amount of iodine is essential as well. A daily pregnancy supplement including at least 150mcgs. of iodine is recommended for women contemplating pregnancy, pregnant or breastfeeding. Australian research shows 50% of pregnant women are iodine deficient. Both inadequate thyroid function and iodine deficiency can affect the development of the foetal brain of your baby and lead to lower intelligence and learning difficulties in children. All children are entitled to enjoy the life they were intended. 

Good Thyroid Health during pregnancy and breastfeeding is essential to sustain the pregnancy and the developing foetus.

If a thyroid disorder is determined, close pathology monitoring and treatment are essential.

Please speak to your treating doctor or obstetrician to discuss thyroid testing.
