What severe complication can excessive iodine intake during gestation potentially cause in an unborn baby?
Significant excess iodine during gestation can cause the unborn baby to develop an enlarged thyroid gland that may compress the windpipe.
The developing fetus is acutely vulnerable to high levels of iodine exposure received through the mother. When a pregnant woman consumes excessive iodine via kelp supplements without medical guidance, this surplus can severely impact the developing system. The critical risk is that this exposure can lead to the enlargement of the fetal thyroid gland, a condition known as fetal goiter. In severe instances, this enlarged gland occupies too much space within the confined fetal environment, leading to physical compression of the infant’s windpipe, which subsequently causes potentially life-threatening breathing difficulties immediately upon birth.
