Clinical Information
  • An enlarged thyroid. It may be caused by too little iodine in the diet or by other conditions. Most goiters are not cancer.
  • Enlargement of the thyroid gland that may increase from about 20 grams to hundreds of grams in human adults. Goiter is observed in individuals with normal thyroid function (euthyroidism), thyroid deficiency (hypothyroidism), or hormone overproduction (hyperthyroidism). Goiter may be congenital or acquired, sporadic or endemic (goiter, endemic).
  • Enlargement of the thyroid gland usually caused by lack of iodine in the diet, hyperthyroidism, or thyroid nodules. Symptoms include difficulty in breathing and swallowing.
  • Enlargement of the thyroid gland.
