What is a Goiter?

A goiter is the enlargement of the thyroid gland. When the gland enlarges, you may see or feel a swelling on one or both sides of your neck or notice that your collars or necklaces have become tighter.

A goiter may develop in a person with hypothyroidism because the thyroid gets bigger in an attempt to produce more hormone. In hyperthyroidism, the thyroid cells may multiply too fast and cause the thyroid to grow. Multiple nodules can also make the thyroid larger.
