What causes goiter?

Answer 1

Goiter is primarily caused by an iodine deficiency in the diet. The thyroid gland requires iodine to produce thyroid hormones, and if the body lacks sufficient iodine, the thyroid gland enlarges in an attempt to produce more hormones. In regions where iodine deficiency is prevalent, goiters are more common. However, goiters can also be caused by other factors such as thyroid nodules, thyroid inflammation (thyroiditis), certain medications, pregnancy, and some genetic conditions.
