Thyroid disorders affect one in twenty people in the UK – could you be one of them?i
The thyroid gland is small, but mighty. It regulates how quickly our mitochondria produce adenosine triphosphate (ATP), the ‘energy currency’ of our body, and in doing so, underpins metabolism and the health of every body system.ii Its key tools are thyroid hormones that communicate with our body cells - thyroxine (T4) which can be converted to the more active triiodothyronine (T3).
If the thyroid functions too slowly, as in hypothyroidism, there is too little fuel to feed the fire and metabolism becomes sluggish. Yet, if the thyroid functions too efficiently, as in hyperthyroidism, there is too much fuel to feed the fire and metabolism starts to work too fast. As hypothyroidism is much more common, this is what we will focus on in this article.
