The thyroid gland is a butterfly-shaped gland that is located in your neck. It secretes hormones, namely Triiodothyronine (T3) and thyroxine (T4). Collectively, these two hormones are referred to as thyroid hormones. They play a significant role in the body’s growth and development. It also regulates the body’s metabolism i.e., it controls the heart, digestive functions, muscles, bone maintenance, and brain development.
In certain conditions, whenever the body needs more energy, like during the growth phase or during pregnancy, the thyroid gland produces more hormones. To make the exact amount of hormones, the pituitary gland tells the thyroid gland whether to release less or more hormones into the bloodstream.
The thyroid helps in regulating the process of transforming the food that we consume into energy. This energy is used throughout your body to keep many of your body’s systems working correctly.
Iodine is needed in the right amounts for the synthesis of thyroid hormones. Our bodies can’t produce it, therefore we need to get enough of it in our diet.
If the thyroid gland is not functioning properly, i.e., if it becomes overactive (hyperthyroidism) or underactive (hypothyroidism), it can lead to health problems and affect normal functioning of the body.
