Thank you for your question. I do not recommend undergoing a tummy tuck procedure and BBL at the same time. Because you will need to be on your back after a tummy tuck, and on your stomach after a BBL, having both procedures at the same time will cause you to jeopardize one or both of the procedures. Make sure you're working with a board certified plastic surgeon with expertise in these areas.
These two procedures can be completed in one surgery. Schedule a consultation with a board certified plastic surgeon who performs these procedures frequently to discuss your current health, anatomy, and end goals.
