Hyperthyroidism (
overactive thyroid
A goiter can sometimes occur when your thyroid gland produces too much thyroid hormone (hyperthyroidism). In someone who has Graves' disease, antibodies produced by the immune system mistakenly attack the thyroid gland, causing it to produce excess thyroxine. This overstimulation causes the thyroid to swell.
