Will treating hyperthyroidism help treat obesity as well?

Most people will tell you that having an overactive thyroid is usually associated with weight loss. In my circumstance, however, I have an overactive thyroid, but I’m fairly obese. I don’t really understand much of the biology around it, but I thought that maybe because my appetite is so high, it could be contributing to my weight problems. So, I’d love to know if there’s any way that treating my hyperthyroidism will help treat my obesity as well? I'm getting so desperate that I've even considered getting a balloon pill to curb my appetite! Thanks all.
