Thank you for your inquiry regarding the possibility of undergoing a Brazilian butt lift (BBL) with a BMI of 33. As a plastic surgeon, I can advise you that while BMI is a significant factor, your overall health status is a critical consideration. Prior to any surgical procedure, you will be required to undergo several health assessments, such as EKGs, urinalysis, and other tests, to ensure that you are medically fit for the surgery. I have performed BBLs on patients with BMIs higher than 33, as long as they are in good health. Although a physical examination would be necessary to evaluate your body type accurately, based on your description, it seems that you may have sufficient fat for a successful outcome. I wish you the best of luck and encourage you to consult with an experienced, board-certified plastic surgeon. Good luck and thank you for your question.
