stomach shrinking?

Hey ladies, so lately i've been getting full very easily and just the last day or two i have been feeling hungry but havent had an appetite? Its weird. 
I've been cutting down on portion sizes and been watching what i eat but idk what it is. 
Is it possible for my stomach to shrink?
