I am really wanting a BBL sometime next year. I am 5"7 currently weighing 150lb.. What is the ideal weight?

There's no exact weight you need to have this procedure. You just can't be too skinny (you might not have enough fat to work with) or being overweight (you might end up with laxity on the abdominal area). In your specific case, your weight is ok for your height. I hope this answer was helpful. 

Hi... thank you for the question... There is not an ideal weight for a BBL procedure, all that is needed is enough fat donor sites, this varies from body to body, repost this with a photo in order to give our specific opinion.. 

Hello,Thank you for your question.  There really is not an ideal weight for a BBL. The ideal patient has a normal range healthy BMI, minimal to no health problems and has adequate fat stores in order to transfer sufficient fat to the buttock.A BBL is a combination of fat transfer from multiple donor site to the buttock along with liposculpting and contouring of the lower back and and hips.  Depending on your current appearance you may require a significant amount of fat or a moderate amount.  This is very difficult to determine without photos however. At 5'7" and 150lbs you are at a healthy weight for your height.  The ideal weight for a BBL is your personal goal weight or even slightly higher in order to ensure sufficient fat is present for the surgery.  I recommend meeting with a board certified plastic surgeon who can examine you and with whom you can discuss your personal goals so that you two together can come up with a plan to achieve your body contour desires. Best of Luck!Dr. Rednam
