Hi
It probably could be. I'm 8 months out and had the tiniest piece of Christmas cake at a works do the other night and came home went to bed and an hour later, 2 after eating the cake I was up shaking, sweating and needing to be sick and go to the loo. I googled this and there is 2 types of dumping, one of them delayed. It was an awful feeling and really took me by surprise.
