Fun fact #1 – TSH’s job is to stimulate the thyroid gland to produce thyroid hormones (both T3
and T4).
Fun fact#2 – if the TSH level is high, it is yelling at the thyroid gland to produce more thyroid
hormone – not always achievable due to thyroid damage.
Fun fact #3 - TSH provides information on pituitary function and how responsive your thyroid
gland is to pituitary function.
Fun fact #4 - TSH level can be manipulated depending on which thyroid medication you are
taking and how much.
