Your thyroid is a small, butterfly-shaped gland located in the front of your neck. Its main job is to act like a thermostat for your body, producing hormones that tell your cells how fast to work. When you have thyrotoxicosis, also known as hyperthyroidism, this gland goes into overdrive and produces far more hormones than your body actually needs.
Think of your body like a car engine. Normally, your thyroid keeps the engine running at a steady, comfortable speed. With this condition, it is as if the gas pedal is stuck to the floor. Your body processes energy so quickly that you may feel like you are constantly running a race, even when you are sitting still.
