A goitre (sometimes spelt  goiter ) is an abnormal swelling of the thyroid gland that causes a lump to form in the neck.

A shortage of iodine in the diet is a common cause of goitre, especially in areas where the soil has little iodine. If a personâs diet is too low in iodine, the pituitary keeps sending chemical messages to the thyroid, but without effect. In attempting to make more thyroid hormone, the gland gets larger and larger.
