The thyroid gland can be found wrapped around the trachea below the Adam’s apple. The thyroid is important because it produces a hormone known as thyroxine which affects everything from metabolism to heart health. A healthy thyroid is important for good health. But when the thyroid produces too much or too little of said hormone, the consequences for our body can be unpleasant. There are different types of thyroid disorders that affect both the structure and function of the thyroid.
