Can I go from a C to a double D with fat transfer?

Thank you for your inquiry.  Fat harvesting and subsequent cup size increase depends on factors such as existing breast tissue, laxity of the breast envelope and how much fat can be harvested.  I prefer patients to be at a comfortable and stable weight prior to surgery and do not recommend weight gain.  Without photos it is difficult to offer you an opinion, however, I have seen 1-2 cup size increase, depending on the individual patient.

There is a limit to the size increase one can obtain with fat transfer not based soley on the amount of fat available but also on the amount of fat that can be placed evenly and take as a vascularized graft.  This is the main limitation of this technique.  Therefore it would take multiple sessions to graft fat to your breast and achieve a 2 cup augmentation. 

Generally gaining weight will make your fat cells expand and make them more fragile, similar to a bubble.  Even if they survive, as you lose weight the cells will shrink, as will the breasts.  Also, it is important to remember that your breast can accommodate only so much fat per procedure.  The BRAVA suction apparatus can increase the amount of fat transferred in one setting which may be an option of you.   The general expectation after fat transfer to the breasts is one cup size increase.  You may need to have multiple procedures to achieve your goal. An in-person exam with a
board-certified plastic surgeon is the best way to assess your needs and
provide true medical advice. Best of
luck. Dr. Michael Omidi

Fat injection to the breast often does not produce the volume that patients desire in a reliable way. Implants will more than likely get you to the desired volume. Good luck.

Thank you for sharing your breast fat transfer question.  Without the benefit of an in person exam it's impossible to diagnose and give suggestions to your questions.  However, several things to consider:  plastic surgeons rarely guarantee cup size increases since bra manufacturers all differ in their sizes/measurements; it's rare for fat transfer to the breasts to yield a two cup size increase; it's important to meet only with a board certified plastic surgeon who has significant experience in fat transfer to the breasts.  Open communication with your surgeon is key to be sure your aesthetic objectives can be met with the surgical plan.  Be sure to look for a plastic surgeon with these credentials:*Board Certified by the
