It's possible, the connective tissue between bones can change causing reduction in hand, feet size, and height is the theory I've seen, but not everyone seems to get it, I'm really hoping I won't be a US size 12 forever, but I've got more weight loss to go, went down a size already from weight loss, no HRT yet.
You're pretty young though, bones fuse at around 25, so you'll get more changes than some of us.
