Triiodothyronine (T3) is a thyroid hormone that plays a role in nearly every physiological process in the body. It plays a key role in development, growth, the regulating of heart rate, metabolism and the body's temperature. Possible thyroid issues can be hyperthyroidism, hypopituitarism, primary or secondary hypothyroidism and thyrotoxic periodic paralysis. A thyroid disorder can create symptoms of anxiety to constipation.
