Respectfully, I think you are asking the wrong question.
The FIRST question SHOULD be :
"What bothers me about my tummy is ...
A. The loose skin pooch when I lean over, (which got worse after the baby(ies).
B. the giggly fat on my hips and tummy (even though I never had a baby).
C. I am bothered by BOTH A and B.
Rather than picking a procedure and hope things will just magically turn out OK, identify what really bothers you and THEN pick the proper tools to fix it.
IF you have had a baby (or more), your tummy has been stretched and NO EXERCISE nor liposuction will bring the separated muscles back to the midline. You will need a "Full" tummy tuck.
If you only have localized fat deposits, especially if you have NOT had a child, then a well performed liposuction procedure would remove the fat (BUT it will not markedly shrink loose skin).
If your surgeon is a REAL Plastic surgeon (check him/her on the website of The American Society of Plastic Surgeons - www.PlasticSurgery.com - You may be shocked to find out that he is not) - I would ask him/her how much of a muscle separation do you have and might you be better served with a Full tummy tuck and no liposuction?
The other alternative is to have the liposuction and let it heal completely BEFORE considering ANY abdominoplasty. You may actually like the result and will not go ahead and have such a procedure.
