DON'T do this procedure. I had it done a little less than a year ago. I had a saggy bum (33 years, four pregnancies 120lbs 5’2”) I have never been obese; I have since learned that I was never a candidate for this type of procedure. My doctor sold it to me as a 'butt lift' but it was actually a 'belt lipectomy' which is part of a body lift procedure. I had no idea how it would ruin my body.
There were so many things that I wasn't told about the procedure. For example I was told that I would be able to hide the scar with a "string bikini" (my dr.'s words not mine), that was/is a lie. The scar is MUCH higher than promised I cannot hide it even with some of my jeans. He also created a false buttocks crease that I was not told about. I had no idea that he would be elongating my butt! It really is awful and I've had to pay extra money (to a different surgeon) to do repair work, it is likely that I am going to have to have more revisions done and I'll still be left with a horrid scar.
I would never have this procedure done had I known the end result.
