If we had to break it down into the big classes of hormones that it produces. So one big hormone that it produces, or what one organ that it controls is the thyroid gland. So the thyroid gland is heat and cold intolerance. It’s what, to some extent, gives us the energy to get through the day. People without thyroid hormone get very, very lethargic, hard to arouse and wake up, and ultimately a very, very low thyroid level can even lead to death. Pituitary tumors that produce thyroid hormone are very, very rare. In fact, it’s usually the opposite problem where you’ve got a pituitary tumor and it doesn’t allow the normal pituitary to won’t function right and people get a slightly low thyroid state.
