Thyroid disease is a common problem that can cause symptoms because of over- or under-function of the thyroid gland. The thyroid gland is an essential organ for producing thyroid hormones, which maintain our body's metabolism. The thyroid gland is located in the front of the neck below the Adam's apple.
The pituitary in the brain signals the thyroid to produce it's hormone through the release of TSH (thyroid stimulating hormone). The TSH stimulates the thyroid gland to produce two different hormones; T3 (7%) and T4 (93%). T4, which contains 4 molecules of iodine, even though produced in abundance is the inactive form and has to be activated in the body into T3, the active form.
The inactive T4 is transported to different parts of the body like the liver, the kidneys and the gut by a transport protein called thyroglobulin. 60% of the conversion from T4 to T3 happens in the liver. A chemical process takes one of the iodine molecules off the T4 and activates into T3. Every cell in the human body has a receptor for T3 to stimulate it to do its function, from your eyes to your muscles even your hair. So you can see that T3 is a very important hormone for the body.
Now that we know what the thyroid produces and why it is important, let us address the factors that can make the thyroid dysfunction. See the thyroid CAN NOT primarily dysfunction, there are many other factor in the body that affect it's working. We will address each one separately in a video series that you can find on our YouTube channel or even at the bottom of this page.
