alexandrivxo. The reason most plastic surgeons in the United States do not do both these procedures simultaneously is 2-fold. Firstly, recuperation would be extremely difficult because you cannot sit or lay on your butt or back for at least 2 weeks after BBL. If Tummytuck is done simultaneously, you cannot lie on stomach, too painful; only option standing or laying on sides! Secondly, each of these procedures carries a slightly higher risk of either blood clots or fat particles breaking away and traveling to the lungs, a potentially life threatening condition called pulmonary embolism. Doing both procedures at same time statistically increases those risks, which is unacceptable to most plastic surgeons here in the U.S. Safety is a primary concern here, not necessarily so in third world countries offering mega operations at a giant discount. Better to do the BBL first to harvest maximal fat for transfer to butt, then 3-6 months later do the Mommy Makeover. Much safer option and probably better result! Be sure to consult with a board certified plastic surgeon. Good luck!
