Thank you for your question. You are a good candidate for both surgeries, but you should decide which body part bothers you more. If you start with a Tummy Tuck, the surgeon will remove the excess skin and tighten abdominal muscles, giving you a firmer and more contoured midsection. This gives you a better idea of your overall proportions, making assessing how much fat to transfer during a future BBL easier. However, the disadvantages are that some surgeons may remove fat through liposuction during a tummy tuck, and it cannot be used for fat transfer to the buttocks. This means you may lose some potential fat donor sites that could be used for your BBL. Also, while your abdomen will look better, the lack of enhancement to your buttocks may leave you frustrated until the BBL is done. On the other hand, if you start with the BBL, you will have a fuller, more rounded buttock shape and an improvement in your curves by using your current fat stores, such as your abdomen, flanks, or thighs, which also slims these areas. However, the disadvantage is that you will have excess loose skin after removing the fat cells from these areas. Also, if you undergo a BBL first and then a tummy tuck, the fat transferred to the hips or buttocks might shift or stretch, potentially altering the BBL results.
