What is the Role of the Thyroid?

The thyroid produces two main hormones, thyroxine (T4) and triiodothyronine (T3). These hormones help regulate many bodily processes, including:

  • Metabolism: The body’s rate of burning energy.
  • Growth and development: The thyroid helps regulate the body’s growth and maturation.
  • Bone Health: Proper thyroid levels help regulate calcium levels in the bloodstream and healthy bone growth.
  • Hormone Balance: Too much or too little of the thyroid hormones can cause problems with other hormones in the body.
