Can EH come on way later?

I’ve been recovered for ~2-3 months, I’ve regained my period, and put on a ton of weight to the point of now kind of needing to keep an eye on things and think about moderating but I’m not restricting

All of a sudden I’m a black hole. I will feel very very full quickly, but then a half hour to an hour later my stomach is growling. I’m chugging water in the hopes that it’s just thirst but it isn’t working and I’m weight restored per my doctors. I don’t know how to deal with this
