I've heard of it. Hormonal problems can really do some strange things to a body. If it is indeed your hormones, and you are given something for it, it's still up to you though to lose weight (if that's what you're going for) and eat healthy - getting your hormones fixed up will just help you out.

When I was younger, my hormones were imbalanced, and it messed up my cycle, caused cysts, and made me extremely emotional - I could even cry over simple things, like a commercial - and come to think of it, it even caused some acne.
