Can BBL get rid of my stomach fat and sides fat or I strongly need BBL w/ Tummy Tuck??! (photos)

I think you need a TT at a minimum (assuming you are done with child bearing).  A 90 lb weight change is substantial and typically creates a lot of loose skin.  A BBL alone could improve your contour but your abdomen (which also looks like it may have some rectus diastasis) will not.  It will most likely remain convex and that shape competes with and masks the shape and projection of your backside.  One reason why you rarely only see lateral and posterior views of BBLs on websites is because the abdomen is loose and distorted.  I have ton a lot of tummy tucks of post-BBL patients from other practices.  That aside, you can do them together or in stages with the BBL performed first followed by a TT at a later date if so desired.  Good luck.  

Hello and thank you for the question. You can do BBL alone or with the Tummy tuck. Liposuction has the risk of leaving loose hanging skin. If you are done having children, then the tummy tuck would give you a flatter stomach. You should consider 2 weeks off of work and about 1-2 months out of the gym. Remember that some of the fat that is transferred does not last long term, but typically about 70% remains. 

You should have several consultations with board certified plastic surgeons before making any final decisions. 

As always, best to be healthy, no smoking, and make sure any health concerns you have are managed by your primary care md. 

Best to you.
