The thyroid responds to signals from the hypothalamus and pituitary in order to appropriately maintain to the body’s metabolic needs. The hypothalamus is responsible for managing hunger, thirst, sleep, hormones, body temperature and other important functions. It is also constantly monitoring thyroid hormone levels and when more thyroid hormone is needed, it sends out a signal known as thyrotropin releasing hormone (TRH). This hormone travels to the pituitary, which is our master hormone gland, and triggers it to release thyroid stimulating hormone (TSH). TSH is sent directly to the thyroid, which is then stimulated to produce more thyroid hormone, or T4 (6.) As mentioned before, standard thyroid testing will look at TSH and sometimes T4 and T3.
