Hello vannac21, Thanks for your questions! I would recommend asking your plastic surgeon if he/she requires you to lose weight or not depending on whether he/she is planning to do a full body Liposuction or just a limited Liposuction to harvest the fat. Based on the information you’ve shared about your height and weight, your current Body Mass Index (BMI) estimate is 29.2. For procedures that involves longer incisions, such as abdominoplasty and breast reduction surgery, it is ideal to achieve a BMI of less than 30 to minimize your risks for complications, such as wound dehiscence and infection. I do suggest to continue having a healthy lifestyle with an exercise regimen and diet plan before and after your surgery. Wishing you the best! Dr. De La Cruz.
