Once you get to a certain age, no matter what's ailing you, someone recommends that you get your thyroid checked. Can the thyroid really be at the root of so much? Actually, yes, it can. It's important to pay attention to what's going on with your thyroid, and to do that, you need to know a little more about it.
Your thyroid is a gland located in the front of your neck between your voice box and collarbones. It's about the size of your thumb and shaped like a butterfly.
