I know its a long way off, but i am really worried about having a really saggy tummy once iv lost all my weight. After having a c-section with my first son my tummy became very saggy, and has no muscle tone any more it just hangs there. Once i lose my excess weight will excersise help to lift it or will i end up having to have a tummy tuck A.K.A Abdominoplasty. If yes. Is it something i could get done on the NHS??
