Why won't some doctors do a tummy tuck and a BBL at the same time?

Thank you for your question.  Similar to some of the answers below, I don't do a TT and a BBL at the same time.  There are several reasons for this.1.  When I do a BBL, I do an aggressive lipo of the abdomen, waist and lower back.  When you do that and a tummy tuck at the same time, you increase the chance of having wound healing complications.2.  When I do a BBL, you cannot sleep flat on your back for 3 weeks.  When you do a tummy tuck, you are not going to want to sleep on your stomach because it will be sore and you will have drains coming out.

I am not a proponent of doing a buttock fat transfer at the same time as abdominoplasty. The tummy tuck usually requires the inability to fully straighten up in order to facilitate the best result. Whereas fat transfer to the buttock area usually requires staying off of this area directly for several weeks postoperatively. All unnecessary pressure on the buttock area following fat transfer could reduce the overall final result by preventing the transferred fat from creating the best possible result.. For more info- you can read my blog here:

These two procedures in particular are not done at the same time because the recovery of one would affect the recovery of the other.  This is mainly due to positioning during recovery (tummy tuck patients are typically sitting in a reclined position on their back, while BBL patients are laying on their stomachs).  Fat transfer is more successful when one is able to not compress the transferred fat significantly for extended periods of time.  This is especially true for the buttocks, where a large amount of fat is typically moved.  This allows for the transferred fat to develop its own blood supply by which it can be noursished and survive indefinitely.  If this does not occur, those transferred fat cells will not survive, and will be lost, thereby minimizing the effect of the procedure.During a tummy tuck the discomfort associated with moving around much in the early days of recovery means people sit quite a lot.  This would have a negative effect on the fat transfer from the BBL.  Hope this makes sense to you.  Seek a plastic surgeon certified by the American Board of Plastic Surgery for your procedures and education as you find an appropriate surgeon.
