Would I see decent-moderate results from a Butt Augmentation via Fat Injection?

At 5'8", 125 lbs, you are quite lean and unlikely to have enough fat to make a significant difference, especially in the long run.  Allow me to share with you some information that you may not hear elsewhere. There are
only two proven safe and relatively effective methods for Buttock Augmentation
and Hip Augmentation: 1) Autologous Fat Transfer (using your own fat,
transferring from one area of the body to the other) and 2) Buttock/Hip
Implants (semi-solid silicone rubber implants that cannot rupture &/or
leak). Both are very good options so what it comes down to, like any surgery,
is proper patient selection. Indeed because at least 50+ % of the fat
transferred will melt away within a year, most patients are not good candidates
because they lack an adequate amount of fat to harvest. Another tip is that if
you purposely gain weight (i.e. fat) for the procedure, the fat you lose first
as you get back to your baseline weight is that very same fat that was
transferred into your buttock...so don't fall victim to this
recommendation.  Although using your own fat is relatively safe, the one
serious complication that can rarely (< 1%) happen is "fat
embolism" in which some of the fat gets into the blood stream and travels
up into the lungs, heart, and/or brain causing serious problems. This
complication is more likely to happen with the larger amount of fat being
transferred. This is
even more likely to happen when using fillers like PMMA and hyaluronic acids.
Also fillers, when injected in large quantities, have a relatively high
tendency to migrate away from the original area they were placed and tend to
stimulate a lot of inflammation and a subsequent disastrous amount of scar
tissue/hardening.

Thus
buttock/hip implants become a very good, safe, and long term reliable option
for most patients seeking buttock augmentation (at least in my practice). I
prefer to insert the buttock implants through a single 2 ½ inch long incision
over the tailbone (concealed within the crevice between the buttock cheeks) and
the hip implants through a ~ 1 inch incision just below the beltline above the
hip region. The buttock implant should always be placed under or within the
gluteus maximus muscle. In this position, the implant is less palpable, less
visible, and does not sag or shift/migrate over time unlike implants placed on
top of the muscle. Therefore it is extremely important to seek consultation
with a board certified plastic surgeon who specializes in this procedure. And
in this case too, at least in my surgical practice, the infection rate is
minimized to ~5%. Glad to help.

I perform the BBL on
thinner women frequently with very good results. I also perform buttock
implants as well. I would find a board certified plastic surgeon who
performs both to help you make this decision.Kenneth Hughes, MDLos Angeles, CA

Hello dear!!
Thanks for the question and provided information as well.
Unfortunately, without pictures, it is very difficult to give you a proper answer.
In general, you need to be physically healthy and at a stable weight, have realistic expectations, be a non-smoker and your BMI needs to be 30 or less. l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

Hi. Thank you for your question. Is really hard to tell without evaluating you, to assess if you have enough fat to have a moderate result with the Brazilian butt lift; but with the numbers you posted, I'm guessing you are to slim to get a drastic change just with fat. Butt augmentation with implants is the other recognized safe method of achieving Butt enlargement. In my practice I perform both fat grafts and Butt implants for Butt enhancement procedures. Remember to consult with a board certified plastic surgeon who is comfortable performing these procedures, in order to get the best opinion related to your case. 

Without an exam in person, it is difficult to say if you have enough donor sites for obtaining fat to be placed in your buttocks. Good luck.

From the measurements and dimensions you have stated I feel you are quite slim and would not have enough fat to create a significant amount of fullness to the buttock area.
