How much fat is need for a fat transfer to breasts and a Brazilian butt lift?

The amount of fat needed for fat transfer to the breasts and buttocks is dependant on how much bigger you want to be in each area.  Keep in mind that 1/3rd or so of the volume injected will not survive as fat.  Two of the best ways to ensure the highest possible fat survival is to avoid smoking and to choose your surgeon well.  The concept of suctioning fat and injecting sounds so simple.  Yet the survival rate varies significantly with the technique used.  This includes how it is suctioned, processed, and injected.  Carelessness or impatience at any stage makes the surgery potentially far less successful.  Not everyone is cut out for the meticulousness of the surgery.  Make sure that it is something that your surgeon does a lot of.Dr Rodger ShorttAssistant Clinical Professor &Director of Cosmetic Surgery Training,McMaster University

An examination is necessary to determine if you have enough donor fat to perform both procedures.  at 5'4" 140 lbs. it seems that you may have enough for both procedures, however an evaluation is necessary before making that determination.  Best of luck.  Dr. Michael Omidi

I have had exactly 0 patients that have said that their breasts or buttocks are too large after one session of fat grafting. More often, a second grafting procedure is used to add even more size to the areas desired. If your breasts are small to begin with, there is only so much fat that can be successfully grafted in one session. Generally this will give you an increase of one cup size. If you want more, you will require a second grafting procedure.Planning should involve a thought process that considers which areas to take the fat from for the initial session, reducing those areas maximally, and leaving other areas in place for a second session if needed.

Typically I consider grafting 150cc -200cc of fat graft per breast the max I would do at a session.  Grafting to the buttock has to much more significant per side to have a significant change.  This is possible but with an exam and consultation I can cannot be of more help.

This is a very difficult question to answer without seeing you. In broad terms, I would expect to transfer at least 300-600 cc of fat to each buttock, and anywhere from 100-350 cc of fat to each breast. That would require around 2-2.5 liters of fat harvest from the rest of your body. Without seeing you and examining the areas of fat to be harvested, and without knowing the results you are looking for, it's impossible to give you an answer. Spend some time in person consulting with a well trained and experienced plastic surgeon, and you will get good advice!I hope this helps!
