Hello uniqu31, I appreciate your questions! I would recommend asking your plastic surgeon if he/she requires you to lose weight depending on whether he/she is planning to do a full body Liposuction or just a limited Liposuction to harvest the fat. Have in mind that there are limits to the amount of fat that can be safely removed. Based on the information you’ve shared about height and weight, your current Body Mass Index (BMI) estimate of 35.4 surpasses the ideal range recommended for a successful BBL surgery and recovery. The higher your weight or your BMI are, the greater the risk for anesthetic and surgical complications such as wound dehiscence, venous thromboembolism, and infection, among others. During the first meeting with your surgeon, you will have the opportunity to discuss your cosmetic goals and, usually, he/she will show you before-and-after photos of similar cases and answer any questions. Best regards! Dr. De La Cruz.
