Iodine in Pregnancy: Why It’s Essential & How to Get Enough
Pregnancy journey is nutritionally demanding. An expecting mother needs to take all the essential nutrients to prevent any deficiencies. Out of all the nutrients, iodine is the one of the most important. It plays a crucial role for the synthesis of maternal thyroid hormones which are essential for foetal brain, nervous system, and cognitive development. Your body needs iodine to produce thyroid hormones - thyroxine (T4) and triiodothyronine (T3) which are important for regulating metabolism, energy production and so on.
Let us understand the importance of Iodine in Pregnancy: -
Supports Baby’s Brain Development
During the first trimester, if iodine intake is inadequate, your body cannot produce sufficient thyroid hormones. This can affect the baby’s brain development resulting in learning difficulties, delayed cognitive development, and speech and hearing problems.
Maintains Healthy Thyroid Function
The requirement of iodine in pregnancy increases due to increased maternal thyroid hormone production, greater renal iodine clearance, and the transfer of iodine to the developing fetus. Therefore, if the iodine intake is low, the thyroid gland can enlarge, and it may lead to hypothyroidism. As a result of which the risk of miscarriage, still birth, preterm birth, low birth weight, and pre-eclampsia increases. However, adequate levels of iodine may help maintain balanced thyroid hormone levels supporting the maternal and the foetal health.
Supports Baby’s Growth and Development
Other than brain development, iodine helps with skeletal development, nervous system maturation and overall physical growth.
What are the key signs of Iodine Deficiency in Pregnancy?
Deficiency of iodine pregnancy may lead to: -
- Goitre, which causes swelling at the base of the neck
- Persistent Fatigue and Weakness due to the low thyroid hormone production.
- Slowed metabolism resulting in increase in weight
- Feeling excessively cold
- Dry skin and hair thinning
- Cognitive issues like poor concentration or memory lapses.
How Much Iodine Does a Pregnant Woman Need?
The recommended iodine intake for Indian pregnant women and breastfeeding women is 250 µg/day. This increased amount (compared to 150 µg/day for non-pregnant adults) is necessary to support fetal brain development and increased maternal thyroid hormone production.
What are the best iodine sources pregnancy?
- Iodized Salt - A reliable source of iodine; however, salt intake should be limited during pregnancy to reduce the risk of preeclampsia while ensuring adequate iodine intake.
- Dairy Products - Some of the good sources of iodine include milk, yogurt and cheese.
- Seafood - Fish and shellfish are rich in iodine. But some fish contain high levels of mercury which can impair fetal brain and nervous system development; therefore, you should consume in moderation and only when well-cooked.
- Eggs - It is highly preferred and contains a moderate amount of iodine.
- Grains & Cereals - Whole grains and fortified cereals can contribute small amounts of iodine, depending on soil content and fortification
- Prenatal Supplements - Consuming good quality prenatal vitamins that includes high quality iodine helps to meet the required needs of iodine during pregnancy without any side effect.
Conclusion:-
Iodine is an essential nutrient needed for a pregnant woman. It supports normal thyroid hormone production, which is important for the baby’s brain development and cognitive function, as well as the mother’s health. Additionally, it lowers the risk of miscarriage, preterm birth, maternal and foetal goitre (enlarged thyroid gland), congenital anomalies and neonatal hypothyroidism. Therefore, it is important to include iodine in your diet.
Since it is not always possible to meet the increased iodine requirements during pregnancy solely through diet, you should take appropriate iodine supplements for pregnancy.
