What is the ideal BMI for a 5'3" woman wanting a Brazilian butt lift?

There is not an ideal BMI.  Being ready for the BBL depends upon your overall health, your body habitus, and your goals. In my practice I look for a BMI approximating 30 (for a weight of 170 lbs and height of 5'3", your BMI would be 30.1) to lessen the risks of complications during and after surgery and to enhance the results of the procedures.  It is best to be within 10 pounds of your weight goal for three months prior to the BBL.  Kenneth Hughes, MD, ABPS Board Certified Plastic SurgeonLos Angeles, CA

A good candidate has enough fat available for transfer in the procedure. The amount of fat that can be transferred in a BBL depends on how much fat the patient has to harvest and the amount of space there is to move the fat into. It is recommended for the patient to have a BMI of 30 or less. If you are too thin, a Brazilian Butt Lift may not be possible.

Thanks for your question. Patients considering cosmetic surgery such as brazilian butt lift should have a stable weight with a BMI of 30 or less in order to minimize risks and maximize results. The closer you are to your ideal weight the better your results will be. That said, you definitely have to choose your surgeon correctly and make sure that he/she has the training and experience to meet your goals with absolute safety.  Best is a Board Certified Plastic Surgeon with specialized expertise in this procedure.
