What is Thyroid?
The thyroid is a gland. It generates thyroid hormones. This small, butterfly-shaped gland usually controls everything in your body. From your temperature, heart rate, blood pressure to metabolism and weight. It even controls the features of your skin, hair, and nails.
The gland takes iodine from your blood and makes the hormone thyroxine, T4. T4 has four iodine molecules. Another thyroid hormone T3 has three iodine molecules.
How does the thyroid gland work?
The thyroid gland stays in constant communication with your brain. Your brain gives a signal to the gland. And the glad raises thyroid-stimulating hormone (TSH) production.
When your body has enough thyroid hormone the gland works normally.
Sometimes the gland doesn’t produce the right amount (too much or too little) of hormones. It means you have thyroid disease.
