In the thyroid, the T4 is stored and bound to what?

Vitamin D
T3 and T4 are synthesized from what?
Tyresone and Iodine
Thyroiditis
Inflammation of the thyroid
It initially causes a leak of hormones that results in symptoms of an overactive thyroid (hyperthyroidism). Over time, the inflammation impairs thyroid hormone production resulting in underactivity (hypothyroidism).
There may be no symptoms. When symptoms occur, they may vary depending on the stage of the inflammation.
Treatment is focused on the underlying cause as well as regulating thyroid function.
Graves disease

Main Sx: Exophthalmos (eyes bulging out)
