The thyroid is tasked with producing hormones, which regulate the body’s energy use. The thyroid may be unable to undertake its functions due to too much or too little production of hormones. Standard treatment for hypothyroidism involves daily use of the synthetic thyroid hormone levothyroxine. This oral medication restores adequate hormone levels, reversing the signs and symptoms of hypothyroidism. Take up the quiz below to know how much you understood from chapter 116 on the thyroid.
