Everyone said by the time I returned back to work it would be gone, and, well, its not. I have never had a weight problem in the past. It's never as easy to lose weight as it is to gain it. In order to lose the weight, a woman after pregnacny is like anyone else. She has to eat fewerr calories than she burns up.
Many women do lose weight, however, after pregnancy.
I don't know if you have been or are now breast-feeding. Also, over time many women will drift back to their natural weight, once they fall back into their old pattern of diet and activity. This can take a while, though, and is often interupted by another pregnancy before the weight is completely lost. So I would encourage you to take an active role in trying to lose the weight, if that is your goal. You can't just assume that it will go away by itself just because the pregnancy is over.
