La deficiencia de yodo grave y moderada durante la gestación y la lactancia afecta a la función tiroidea de la madre y del neonato, así como al desarrollo neuropsicológico del niño. En la mayoría de los países de Europa el estado nutricional de yodo de gestantes y recién nacidos es deficiente, pues las necesidades de yodo en las mujeres embarazadas y en las que amamantan a sus hijos son al menos el doble de las recomendadas para la población adulta. Estudios realizados en España confirman que la mayoría de las mujeres se encuentran en yododeficiencia durante la gestación y la lactancia y muestran que la ingesta de sal yodada no es suficiente para conseguir un estado nutricional de yodo óptimo en esta población. Varios estudios demuestran el efecto beneficioso de la suplementación de yodo de las embarazadas sobre el estado nutricional de yodo y la función tiroidea de la madre y el recién nacido. Las mujeres embarazadas, las que amamantan a sus hijos y las que planifican su gestación deberían recibir suplementos de yodo en forma de tabletas de yoduro potásico.

Severe and mild iodine deficiency during pregnancy and lactation affects thyroid function of the mother and neonate as well as the infant's neuropsychological development. In most European countries, maternal and neonatal iodine status is deficient, since iodine requirements in pregnant and lactating women are almost double those recommended for nonpregnant or non-lactating women. Studies performed in Spain confirm that most women are iodine deficient during pregnancy and lactation, and show that iodized salt intake is insufficient to achieve optimal iodine nutritional status in this population. Several studies have demonstrated the beneficial effect of iodine supplementation in pregnant women on the iodine and thyroid status of both mother and neonate. Pregnant and breast feeding women and women planning to become pregnant should take iodine supplements in the form of potassium iodide tablets.
