WebIt stimulates the production of the thyroid hormones, thyroxine (T4) and triiodothyronine (T3), by the thyroid gland by binding to its receptors in the thyroid gland. Thyroxine (T4) and triiodothyronine (T3) are essential for maintaining the body’s metabolic rate, heart and digestive functions, muscle control, brain development and bone activity. WebThyroid hormone increases beta adrenergic receptor expression on cardiomyocytes which makes the heart more sensitive to excitation through the sympathetic nervous system. Thyroid hormone will also increase GI motility and appetite. Despite increased appetite, weight loss with excess thyroid hormone occurs because of increased metabolic rate.
