World Iodine Excess/ Deficiency / Thyroid Health

Thyroid Health

In the last 10 years there has been a reduction in the number of countries with a public health problem due to Iodine deficiency ( 110 countries in 1993 had a problem ). In 2003 only 54 countries had a continuing health problem. Iodine deficiency is a significant cause of mental developmental problems in children. The plan of universal salt iodization, has been successful, but more needs to be done. Soil iodine deficiency, leads to low levels in food, and results in the thyroid gland failing to make enough thyroid hormone. The result is a series of functional, and developmental problems called Iodine Deficiency Disorders. Cretinism is the most extreme problem. However, the subtle disorders leading to poor school performance, reduced intellectual ability, and impaired work capacity, are the main reason for the universal iodization program. The USA is sufficient in iodine, except in young women during pregnancy.Some need iodine added to their vitamins during pregnancy.

29 countries have excess iodine intake. Excess iodine can be a problem for patients with thyroid diseases such as Hashimoto's thyroiditis. Iodine induced thyroid disorders, can cause hypothyroidism, hyperthyroidism, nodules, and goiter. People with goiters from iodine insuficient areas of the world, can develop toxic hyperthyroid goiter years after entering the US, caused by the increase in iodine intake in our country.
