I'm 5'6", I weigh 170 pounds. I wanted 1400 ccs in each cheek. Is it an achievable goal? Do I have enough body fat for a BBL?

If you want to have 1400cc on each buttock, you need to do it 2 stages. When you get the fat grafting in the buttocks, there is a point where the skin will not stretch more, and the tissues are under too much tension, decresing the blood supply to the grafted fat, and then the fat has less chances of survival. So you can get one surgery with about 800cc for each buttock, wait for 6 to 12 months, and get another surgery for a similar amount of fat injected in the buttocks.

Thank you for your question about Brazilian Butt Lift.The limitation on how much fat can be transferred depends on the amount of donor site fat that you have and on the amount of extra room that you have in your butt to put the fat.  It can't be too tight or it might constrict and kill the fat.To be sure, see two or more board-certified plastic surgeons in your area for a full and complete evaluation to make sure you are a good candidate and that it is safe for you to have surgery.I hope this helps.

Although pictures or an exam would help make a determination, 1400 cc per buttock can be achieved in patients of your height and weight.  I
would search for the board certified plastic surgeon who you feel is
most likely to give you the best results and who performs hundreds of
these procedures each year. I would look at patient reviews as well as
before and after photos on that surgeon's website.Kenneth Hughes, MDLos Angeles, CA
