Tummy Tuck (Abdominoplasty) is a great procedure which if done properly by an experienced Board Certified Plastic surgeon will greatly improve your appearance. Among its uncommon risks may be bleeding, infection, ugly scar, loss of the belly button. But it WILL flatten your tummy, narrow your waist, lift a sagging pubic mound and, if a Lockwood (High Lateral tension) Abdominoplasty is done, it will lift and smooth you anterior and side thighs from cellulite dimpling.
I would NOT have a tummy tuck done if you expect to have more children. This will re-distend your tummy and ruin the surgical result.
As far as going through with it or not - listen to the voice inside. Are you doing for yourself or for someone else? Do you trust your surgeon? If you are doing it to please someone else or do not have full trust in your surgeon - do not have the surgery. Otherwise, get all your questions answered and do what your heart tells you to do.
