Hello teraye.harrien, I appreciate your questions! I would recommend asking your plastic surgeon if he/she requires you to gain or 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. Similarly, the volume of fat that can be safely injected into the buttock varies from patient to patient, and it will depend on the patient's anatomy and cosmetic goals. Based on the information you’ve shared about height and weight, your current Body Mass Index (BMI) estimate of 30 is on the threshold of the ideal measurement for a successful BBL surgery and recovery. The higher your weight or your Body Mass Index (BMI) are, the greater the risk for surgical and anesthetic complications. Therefore, it is ideal achieving a BMI of less than 30 to minimize the risk for complications such as wound dehiscence, venous thromboembolism, and infection, among others. Best regards! Dr. De La Cruz.
