|The thyroid is a small endocrine gland located just below your adamís apple and is often described visually as a butterfly having two halves or lobes.
The thyroid release hormones that influence many bodily functions, such as physical growth and development, metabolism, puberty, organ function, fertility and body temperature. These functions depend on two hormones released from the thyroid gland: tri-iodothyronine (T3) and thyroxine (T4).
The thyroid gland can produce too much of these hormones (hyperthyroidism) or not enough (hypothyroidism). These thyroid hormones play a vital role in the body, thereby influencing all organs. They also determine how fast or how slow the organs should work and when the body systems use energy.
