The thyroid is a butterfly-shaped gland in the neck that regulates metabolism, energy production, and hormone balance. It produces thyroxine (T4) and triiodothyronine (T3), influencing heart rate, digestion, and body temperature. Thyroid disorders, such as hypothyroidism and hyperthyroidism, can affect overall health and require medical management. https://elementalhealthandnutrition.com.au/thyroid/
