Thyroid Hormone

Thyroid hormone comes from the thyroid gland, and is used by all cells. It steps up all cellular function, and is crucial to the use of energy by the cells. If you don’t have the proper amount of thyroid hormone, nothing in your body works right. You become fatigued, lethargic, sleep too much, gain weight, feel generally awful. Even a very tiny amount of thyroid hormone replacement can set things straight again. Thyroid hormone levels fluctuate very quickly, so the generally measured test is a TSH (thyroid stimulating hormone) is a better barometer of your levels. It tells what the level of thyroid hormone has been over time (4-6 weeks) and is actually a hormone secreted by the anterior pituitary gland in the brain. Most thyroid regulation is done based on this test.
