   • An abnormally enlarged thyroid gland: A medical condition characterized by a visible swelling in the neck due to the enlargement of the thyroid gland.

  • The doctor diagnosed her with a simple goiter caused by iodine deficiency.
  • A large goiter can sometimes cause difficulty with swallowing or breathing.

  • The patient's symptoms, including weight loss and rapid heartbeat, pointed to exophthalmic goiter.

Synonyms

Notes on Meaning

The term "goiter" refers specifically to the physical enlargement of the thyroid gland itself, which is a symptom of an underlying thyroid disorder rather than a specific disease. The cause (e.g., iodine deficiency, autoimmune disease) determines the type and treatment of the goiter.
