The thyroid gland affects virtually every organ system in the body. It is responsible for regulating cerebral function, body temperature, and metabolism. Increased thyroid hormones cause an increase in metabolism, energy and sense of well-being and decrease in brain fog. Production of thyroid hormones starts with the thyroid stimulating hormone (TSH), which is released from the pituitary gland and acts on the thyroid gland to produce two types of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). T3 is the active form of thyroid hormone; whereas, T4 is the inactive form and must be converted to T3 in order to be active. The thyroid gland secretes about 97% of the inactive T4 hormone, versus only about 7% of the active T3 hormone. In thyroid disorders, TSH levels can be normal; therefore, additional tests are needed to properly diagnose thyroid dysfunction.
Many people suffer from hypothyroidism, a condition in which the body doesn’t produce enough thyroid hormone. Left untreated, hypothyroidism can lead to numerous health concerns, including obesity, joint pain, heart disease, neurological deficits, fatigue, and infertility. Appropriate and accurate thyroid function tests can easily help diagnosis thyroid problems. Because TSH levels can appear normal in hypothyroidism, T3 and T4 levels need to be tested in order to accurately determine thyroid function. Natural thyroid replacement hormone provides the body with a combination of both T3 and T4; whereas, synthetic thyroid replacement hormone only provides the body with the inactive T4 form which still has to be converted in the body to the active T3 form.
