Hello and thank you for your question regarding undergoing multiple procedures at the same time, specifically tummy tuck, buttock lift, and breast reduction. There is no specific number. The answer depends on multiple factors. These factors include the length of time under anesthesia, your overall health, the anticipated amount of blood loss, the total length of open incisions, and your tolerance to pain, among others. The tummy tuck and breast reduction is also known as the "mommy makeover". This is a common procedure. However, I would not combine it with a butt lift. I think this is too much surgery at one time. I would suggest either undergoing the "mommy makeover " or having the tummy tuck and butt lift. The combined procedure of the tummy tuck and butt lift it's called a 360 circumferential lower body lift. I would suggest you seek a experienced, qualified, board-certified plastic surgeon. Good luck. If you have any questions regarding tummy tuck, abdominoplasty, breast reduction, buttock lift, or 360 circumferential lower body lift,
