I am around 290 overweight and want a BBL. I am 5'8"/5'9" and carry my weight very well. Can I get a BBL? (Photo)

You do need to loose some weight before under going a BBL procedure. Loosing weight will decrease your surgical risks and give you optimal results. Best of luck. 

Hello dear!
Thanks for the question and provided information as well.
Right now your BMI is 43 and it needs to be 33 or less, for you to be considered a good candidate for plastic surgery.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and the best options for you.
Good luck :)

Best to have a BMI below 30 to reduce your surgical complication risk. Seek a plastic surgeon that has great reviews and before/after pictures that are consistent with your goals.

I think that you need to lose weight before undergoing a brazilian butt lift. A lower BMI is safer for your overall health and reduces your risks of complications.
