I don't know what UPMC is as I am in England, but yes you need to get it seen to a soon as possible. A hyperactive thyroid or hyperthyroid can be dangerous. As I said in the article, it makes your heart beat much quicker, you can get the shakes and if it gets too high then your body will start to 'eat' itself. as my doctor put it. In other words, you will lose weight, and your body will turn on itself and cause all sorts of problems. And if you have an accident and need surgery it can kill! Of course, if you are only a little bit high then waiting is an option, but I personally wouldn't take the risk.
