Thyroid

1. What is the thyroid gland?

The thyroid is a small, butterfly-shaped gland located in the neck. It produces hormones (T3 and T4) that control metabolism, energy, growth, and body temperature.

Thyroid disorders are conditions where the thyroid gland produces too much or too little hormone, or develops structural problems (like goiter or nodules).
