The short answer is absolutely yes. You can have a tremendous change in this setting if you have significant fat present in the areas of concern.I hope to see you soon.
You may do liposuction after Tummy tuck or at the same time. If liposuction is done after tummy tuck, I would suggest to leave a minimum of 6 months in between for your body to be healed and swelling to be gone before you have liposuction.
