Thyroid - Types, Symptoms, Causes, Diet and Treatment

The thyroid gland has an important job to do within your body — releasing and controlling thyroid hormones that control metabolism. Metabolism is a process where the food you take into your body is transformed into energy. This energy is used throughout your entire body to keep many of your body’s systems working correctly. The thyroid controls your metabolism with a few specific hormones — T4 (thyroxine) and T3 (triiodothyronine). These two hormones are created by the thyroid and they tell the body’s cells how much energy to use. When your thyroid works properly, it will maintain the right amount of hormones to keep your metabolism working at the right rate.
