Dear Villanelly81,
this may be a lot of procedures all at once. Once you go under anesthesia for more than 4 hours, you may increase your risk of blood clots, infection, etc...
If you were my patient, I would suggest you undergo the liposuction of the abdomen and back, then transfer the fat to the buttocks at once. your surgeon can be more agressive in fat removal, since no skin cut for a TT.
the recovery will be fast, you will not miss work more than 1 or 2 days. and you may loose weight from the procedure. you will have to walk from day 1.
Then you can consider a TT 6 months or 1 year later. the recovery will be longer, with 6 weeks without exercises. But both procedures will be done faster individually, so less risks.
Good luck,
Florence Mussat MD
