Iodine Supplementation for Pregnant Mothers: Why is it Necessary?
A mother lacking iodine during pregnancy may give birth to a child with congenital hypothyroidism, intellectual disabilities, becoming a burden for the family and society. Therefore, to ensure optimal fetal development and the mother's health for childbirth, nurturing, and caring for the child, it is essential to supplement iodine for pregnant mothers according to the doctor's recommendations.
1. What is Iodine?
Iodine (I-iodine) is a chemical element that is very important for human health, especially for pregnant women. This element is naturally found in seawater and in some types of soil. Iodine is also found in marine organisms such as fish, shrimp, and seaweed, as well as in some crops and animal products from land that contains iodine. Additionally, iodine is added to some foods like salt and bread to help supplement nutrition for the body.
Iodine plays a crucial role in the production of thyroid hormones, regulating metabolic functions in the body. Thyroid hormones are also essential for the brain and nervous system development of the fetus, helping to maintain the health of both mother and child. Iodine deficiency can lead to many serious health issues, especially during pregnancy.
2. Why is Iodine Supplementation Necessary for Pregnant Mothers?
A mother lacking iodine during pregnancy may give birth to a child with congenital hypothyroidism.
The role of Iodine for the human body in general and for pregnant women in particular is very important. In the human body, the thyroid gland needs iodine to produce hormones that control metabolism, helping the body grow. During pregnancy, the iodine requirement of the pregnant woman increases by about 50% to meet the thyroid hormone needs of both mother and baby.
The hormones released from the thyroid will help develop the brain and nervous system of the fetus. After birth, thyroid hormones continue to be transferred to the baby through breast milk, ensuring the brain and nervous system of the baby develop. If the pregnant woman does not receive enough iodine in her diet, both mother and fetus may suffer from iodine deficiency.
Iodine deficiency causes the thyroid gland to enlarge rapidly, leading to goiter or thyroid enlargement. At the same time, iodine deficiency also affects hormone production, making it difficult for the pregnant woman to chew and swallow, leading to hypothyroidism which causes weight gain, fatigue, poor cold tolerance, and depression. Additionally, iodine deficiency can significantly impact the brain development of the child during pregnancy and after birth. Some children face many learning difficulties due to iodine deficiency.
The most serious consequence of iodine deficiency is its impact on fetal development. Pregnant women who are iodine deficient are at a higher risk of miscarriage, stillbirth, premature birth, and the child being born with intellectual disabilities due to brain damage, and low birth weight. Moreover, children who are iodine deficient from pregnancy are more likely to suffer from congenital disabilities such as limb paralysis, speech impediments, strabismus, deafness, and mutism. Iodine deficiency also increases the perinatal mortality rate.
2.1 The Impact of Iodine Deficiency on Maternal Health
Iodine deficiency not only affects fetal development but also causes many health issues for the mother. Pregnant women who do not receive enough iodine may experience symptoms such as fatigue, uncontrolled weight gain, and depression. These issues can reduce the quality of life and make it difficult to care for themselves and their future children.
2.2 The Impact on Fetal Development
For the fetus, iodine deficiency can lead to irreversible brain damage, causing the child to have difficulties in learning and development. Studies show that children whose mothers were iodine deficient during pregnancy often have lower IQ scores compared to other children. This highlights the necessity of iodine supplementation during pregnancy.
3. How to Supplement Iodine for Pregnant Mothers?
Iodine supplementation is essential. However, pregnant women need to know how much they should intake, not too much or too little compared to the recommended amount. According to the National Institutes of Health in the United States, the recommended daily iodine supplementation for pregnant women is 220 mcg. If the necessary amount of iodine is not consumed daily, pregnant women can compensate by eating iodine-rich foods or taking iodine supplements as prescribed by their doctor.
To ensure that both mother and baby do not suffer from iodine deficiency, pregnant women should pay attention to:
Organic bread, salt-free bread, or homemade bread usually does not contain iodine. It is advisable to eat packaged bread to supplement iodine, but check the iodine content on the food label of the bread;
Seafood should be consumed, but avoid swordfish, barramundi, etc., during pregnancy as the meat of these fish has high mercury content;
Eggs, meat, vegetables (cooked potatoes, white beans, apples), and dairy products should be consumed;
Women experiencing morning sickness who cannot eat animal products should supplement iodine through medications;
Use iodized salt.
Pregnant women should use iodized salt.
3.1 Iodine-Rich Foods
Iodine-rich foods that pregnant women should include in their daily diet are:
Seafood such as shrimp, salmon, and tuna.
Seaweed, a very rich natural source of iodine.
Milk and dairy products such as cheese and yogurt.
Eggs are also a good source of iodine for pregnant women.
iodized salt, which is the easiest and most convenient option.
3.2 Considerations When Supplementing Iodine
Pregnant women need to supplement iodine appropriately. Consuming too much iodine can lead to health issues, including:
Goiter due to abnormal enlargement of the thyroid gland.
Thyroiditis and thyroid cancer.
Burning sensation in the throat, mouth, and stomach.
Fever, diarrhea, and stomach pain.
Nausea and vomiting.
4. Notes When Supplementing Iodine for Pregnant Women
Supplement the correct amount of iodine, not too much or too little. If the pregnant woman absorbs iodine beyond the limit, the baby at birth will suffer from congenital hypothyroidism. If untreated, hypothyroidism will lead to cognitive impairment in newborns and young children.
Be cautious of the presence of nitrates in foods as they affect iodine absorption. Pregnant women should avoid processed foods and cold cuts, sausages as they contain high levels of nitrates;
If the pregnant woman has previously supplemented iodine due to thyroid issues, inform the doctor;
Potasium iodide (KI) can be used to manage iodine deficiency and thyroid disorders;
Do not use iodine alcohol during pregnancy. Iodine alcohol is a disinfectant used to treat minor wounds. Iodine alcohol is a mixture of 2% iodine and 2% sodium iodide in 50% alcohol. Ingesting iodine alcohol can lead to death.
If planning to become pregnant or currently pregnant, women should visit a hospital to check the iodine levels in their body and find solutions to improve their health in the best way. Changing the diet and paying attention to supplementing necessary nutrients is a way to help pregnant women stay healthy and ensure the fetus develops comprehensively.
5. Conclusion
Iodine supplementation for pregnant mothers is an essential factor to ensure the health of both mother and fetus. Iodine deficiency can lead to many serious issues, from congenital disabilities to long-term health problems for the child. Therefore, iodine supplementation should be carried out in a planned manner, based on the guidance of a doctor and a reasonable diet.
Pregnant women should pay attention to iodine-rich foods and ensure that the amount of iodine ingested meets the needs. Additionally, regular health check-ups and monitoring iodine levels in the body are also very important. With the right measures, mothers can give birth to healthy, intelligent children who develop comprehensively.
