I had a bbl and after 2 years i feel all the fat is gone. If I were to do round 2 is it likely it would happen again?

Unfortunately i hear this similar story from patients at least twice a day. Chances are if it melted away the first time, not much will change the second (or third) time around. This is why many of these patients turn to buttock implants as the only relatively safe, reliable and permanent surgical option for buttock augmentation. Glad to help. 

Having the BBL done a second time is an option as long as the patient has enough fat to be transferred. The revision implies that there is less fat than the first time, and scar tissue will make the surgery much more difficult on the surgeon. The percentage of fat survival in the second BBL should be about the same as the first. The volume loss occurs over the first 6 weeks or so.  The buttock size should have been long lasting after about 3-6 months. After that period of time the volume remains stable assuming weight is maintained. Having before and after photos as well as current photos would have been helpful.

Dear hbunny13,
Fat viability depends a lot of surgeon technique. The fat has to be placed back into the buttocks as soon as possible so that it has a greater chance of survival. It has to be placed carefully so that not too much fat is placed in only one area. In most cases 30-50% of transferred fat is lost after the surgery. If you have enough fat tissue, revision surgery might be an option. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

It would be helpful if you could provide photos of your results for a more accurate answer. During a BBL, some of your transferred fat will resorb and disappear. The remaining fat that is left will fluctuate in size just like fat cells on any other part of your body. It is possible to have a secondary procedure, but this depends on your remaining fat cells. Schedule a consultation with a board certified plastic surgeon for a thorough assessment. 

It is possibleA Brazilian butt lift (BBL) is a cosmetic surgery procedure that enhances the shape and size of the buttocks by transferring fat from other areas of the body: Brazilian butt lift (BBL)ProcedureFat is removed from other areas of the body, such as the thighs, hips, lower back, or belly, and injected into the buttocksGoalTo improve the shape and volume of the buttocks, and sometimes to create an hourglass figureResultsMore rounded and fuller buttocks, and sometimes a smaller-looking waistRisksExpensive, can be dangerous, and there are no guaranteed resultsRecoveryPain is usually minimal, and full recovery takes about six monthsMaintenanceResults should last for many years, but it's important to maintain a stable weightA BBL is different from a traditional "lift" procedure, like a breast lift or facelift, because it doesn't improve sagging or excess skin. A BBL is also different from other butt lift techniques because it doesn't use implants. Candidates for a BBL should have good skin tone in their buttocks and hips, be in good health, and not have medical conditions that would impair healing.

In order to give you sound advice specific to you, we would need to know more. Did you lose weight after you first fat transfer? Did you change your routine post op? For example, starting exercise that you did not do before the surgery. How much fat was transferred? 

So many factors play in BBL results, the most crucial one is how much fat you have left elsewhere, and who did your original two BBLs. If the surgeon was a board certified plastic surgeon who operated at a certified facility and had done a ton of BBL’s you are in good hands. If not see one. You should ask how many BBLs have you done on women in my situation doctor? Do not settle for a vague answers. A minimum of fifty a year would be the answer I would accept. Good luck.

Thanks for writing,I would suggest you see your original surgeon, I have had patient return after long periods thinking the fat was gone. When the old photos come out, WOW, a lot is still there. I believe people get use to what they have and forget the improvement. One always expect some loss, as others have described. A secondary procedure can help re-volumize. Based on your re-evaluation by your plastic surgeon this could be predictive of what to expect.Stephen M. Davis, MD, FACS

Dear Bunny,If the fat was present 6 months post-op and then later disappeared, it would be a strange presentation.  The transferred fat that remains at 6 months would be permanent.  If you lost weight or started working out and noticed the fat disappearing over time, this would be more logical.  A second round ot fat transfer may have the same fate.  Difficult to give you an accurate prediction without more information.Dr T

The fat likely didn't stay based on the BBL technique used. Using VASER liposuction technology, the fat has over a 95% graft take.  This means that your results will be stable as long as you maintain your weight. If you are a good candidate for a Brazilian Butt Lift (BBL), the optimal outcomes are achieved with: 1) use of VASER liposuction to harvest the fat, 2) a closed looped system such as Puregraft to process the fat, and 3) strategic micro-packet transplant technique. As an official VASER trainer, I am routinely referred unhappy BBL patients. One of the most common reasons for disgruntled BBL patients is that patients are not able to accurately communicate their desired buttocks goals to their surgeons.  A buttocks assessment tool can be an invaluable tool to communicate to your surgeon the exact buttocks size and shape you are desiring. A Skype or FaceTime consultation with a BBL specialist can help you get an accurate recommendation and pricing.
