Fact 4: Iodine Deficiency: A Silent Global Health Issue
Despite being largely preventable, iodine deficiency continues to pose a significant health issue globally. It is the leading cause of preventable intellectual and developmental disabilities worldwide. Moreover, it can also lead to hypothyroidism and associated symptoms.
Iodine deficiency is more prevalent in parts of the world where iodine is scarce in the local diet. This includes many landlocked areas where seafood (a prime source of dietary iodine) is less common. However, it’s not confined to developing countries. Even developed countries see cases of iodine deficiency, making it a truly global concern.
One of the primary consequences of iodine deficiency is a reduction in thyroid hormone production. Over time, this can lead to an enlarged thyroid gland, a condition known as goiter. Goiter can cause a visible swelling in the neck and may also lead to breathing and swallowing difficulties.
For pregnant women, iodine deficiency can have severe implications. It can lead to stunted physical and intellectual growth in infants, leading to long-term health and developmental issues. It is why sufficient iodine intake is crucial during pregnancy. (4)
