Thyroid stimulating hormone, or TSH as it’s commonly referred to, is a hormone produced in the pituitary gland that stimulates the thyroid to produce thyroxine (T4). When the body is producing high amounts of TSH, it typically results in lower levels of T4 resulting in hypothyroidism. When the body is producing low amounts of TSH, it typically results in higher levels of T4 resulting in hyperthyroidism.

Hyperthyroidism: A condition in which the thyroid gland produces too much thyroxine
