Answer:

"Graves disease" is also sometimes called "thyroid storm". It's a condition that sometimes occurs when a thyroid gland turns "on" and won't shut off. When too much thyroxine is produced.

There are a couple treatments for the disease, one involves a medication to allow the thyroid glands to slow production until the body can heal, the other involves destroying the thyroid glands either surgically or through radioactive iodine.
