Apetamin to gain weight before a BBL?

I would have to see your starting point to give you a recommendation on this.  I frequently do not recommend weight gain.Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA

Thank you for your question. With Brazilian butt lift we transfer fat from one area of the body to the other.  These fat cells are transferred in microinjections throughout multiple planes in the buttock tissue so that they can gain new blood supply and live in their new home, providing increased volume and shape to the buttocks.  If you put on weight before surgery, there is more to transfer.  But I do not generally recommend this because we augment the buttock during surgery for optimal shape, and if you then lose the weight post operatively you will loose it disproportionately from your augmented buttock and the results could suffer.  We recommend patients to keep their normal weight and body form prior to surgery, and then we are working from a stable situation to create the changes we are working for.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.

Hello dear!!

Thanks for the question and provided information as well. 

It is necessary to see in order to give you any recommendation. Most of the time i do not recommend my patients to gain weight. 
 I recommend you to contact your surgeon to discuss your concerns and talk about your goals.
