No, but the question of ideal weight before a tummy tuck is raised, and also the question of when to proceed when you are overweight.
There are some women who are overweight at the time of their tummy tucks, and they usually have a combination of liposuction of the abdomen, waist and flanks as well as the tummy tuck. They do fine and look good, since the fat that is removed with liposuction gives a much better mid-torso contouring than they could achieve with weight loss alone.
Many women carry the excess weight in their lower body and it is not necessary to reduce the fat in those areas before doing a tummy tuck.
The important question is at what level the excess weight is going to make the operation less safe or when there is really too much circumferential torso and abdominal fat to get a good result.
Every case is individualized. Some women want to reduce the bulk of their abdomen for comfort, not just aesthetics. These might be the women who really have a lot of fat and skin overhanging the pubic area
Some women just have too much weight in proportion to their height and then I recommend weight loss through a specialist medical weight loss clinic. The weight loss doctors supervise the program, and may prescribe weight loss pills. When the patient has lost enough weight to be a safe candidate for surgery and benefit from it aesthetically, then we proceed.
