The thyroid gland is a butterfly-shaped organ located in the base of your neck. It releases hormones that control metabolism—the way your body uses energy. The thyroid’s hormones regulate vital body functions, including:
- Breathing
- Heart rate
- Central and peripheral nervous systems
- Mood changes
- Digestion
- Body weight
- Muscle and bone strength
- Menstrual cycles
- Fertility
- Sexual power
- Body temperature
- Cholesterol levels
In short we can say that thyroid is a master organ which controls almost all body functions
