What should I do if I want to have a flat stomach and big boobs?

Dear B17003138R,
Thank you for your question. It is difficult to say for sure without photos or an in-person consultation, but from what you state your goals are, you may not be able to achieve a dramatic enough result with liposuction and fat transfer alone, where you would be happy with the results. Each procedure may have its limitations. Depending on whether you have had children or significant weight loss, you may be able to better achieve your desired result with an abdominoplasty and liposuction for improved contour, in addition to, a breast augmentation with implants. This may provide you with a flatter tummy and bigger breasts as you mention in your question. I suggest that at this current time, to get your process started, you schedule a virtual consultation with a board certified plastic surgeon to discuss your goals and to develop a plan to achieve them. Best wishes and stay safe!

Based on the description of your surgical goals the recommended procedures would be a tummy tuck with liposuction for contouring and breast augmentation with implants.  If you are wanting a significant increase in breast size then implants may be the better option. The best place to begin is a consultation with a board certified plastic surgeon near you.  You can learn about the procedures and determine if you are good candidate.
