                                Worldwide, iodine deficiency is the most common cause of goitre, affecting an estimated 2.2 billion people. A goitre is an abnormal enlargement of the thyroid gland, which can appear as a visible swelling in the neck. This condition arises when the thyroid lacks the necessary resources to produce its hormones, primarily triggered by a shortage of a specific mineral.
