Over secretion of thyroxine causes ____ goiter?

Hyperthyroidism:

1. When your thyroid gland produces an abnormally large amount of the hormone thyroxine, you have hyperthyroidism (overactive thyroid).
2. The thyroid gland accelerates your body's metabolism, resulting in unexpected weight loss and a fast or irregular heartbeat.
3. Goiters are caused by a lack of iodine in the body. Iodine is necessary for the thyroid to manufacture thyroid hormones.
4. When you don't get enough iodine, your thyroid has to work harder to produce thyroid hormone, which causes the gland to enlarge.

Final answer:

Over secretion of thyroxine causes Hyperthyroidism goiter.
