THE THYROID

The thyroid gland is like the thermostat of your body’s energy system. It releases hormones that control how fast or slow your body uses energy, influencing growth, temperature, and overall metabolism.

  • Produces thyroid hormones (T3 and T4) that regulate metabolism

  • Influences energy production and body temperature

  • Supports growth and development

  • Affects heart rate, digestion, and muscle function

  • Works with the pituitary and hypothalamus to maintain hormonal balance
