Why is hypothyroidism so common now?

Worldwide, environmental iodine deficiency is the most common cause of thyroid disorders, including hypothyroidism [6]. Iodine is an essential component of thyroid hormones, but is also thought to make the thyroid gland more antigenic [2, 3, 33].


Why is hypothyroidism increasing?

Not enough iodine.

The thyroid gland needs the mineral iodine to make thyroid hormones. Iodine is found mainly in seafood, seaweed, plants grown in iodine-rich soil and iodized salt. Too little iodine can lead to hypothyroidism. Too much iodine can make hypothyroidism worse in people who already have the condition.
