whetehr goitre is a inherited or deficiency diseases
A goitre or goiter is a swelling of the thyroid gland, which can lead to a swelling of the neck or larynx (voice box). Goitre is a term that refers to an enlargement of the thyroid and can be associated with a thyroid gland that is functioning properly or not.
Worldwide, over 90% cases of goitre are caused by iodine deficiency. Selenium ( a chemical element necessary for cellular function in many organisms, including all animals ) deficiency is also considered a contributing factor. In countries that use iodized salt, Hashimoto's thyroiditis ( an autoimmune disease in which the thyroid gland is attacked by a variety of cell- and antibody-mediated immune processes ) is the most common cause. So Goitre is a deficiency disease.
