Mommy makeover surgery is surgery that may include many different procedures, and the amount of time each procedure takes determines how long the anesthesia will be. Mommy makeovers almost always involve some type of tummy tuck and some type of breast surgery. Sometimes a routine tummy tuck may be performed, but other patients may need or want more than that, including maybe liposuction of the flanks and back, or maybe a more circumferential body contouring procedure like a lower body lift. Those procedures are different from each other, have different outcomes, and take different amounts of time. The breast surgery, too, will vary from patient to patient. Sometimes a breast augmentation is performed. That's a pretty short operation. Sometimes a breast lift or a breast reduction operation is performed. Those take more time.The length of time an operation takes is one factor in determining how safe the operation may be, but what's really even more important is the overall health of the woman undergoing the surgery, and what her support structure will be once she goes home. For two women undergoing the same operation, a 35 year-old mother of two who is thin and healthy and who has someone who can take a few days off to help her at home probably has less risk of complications than a 45 year-old woman with type 2 diabetes who can't find someone to help her much. In my practice if an operation takes over 4 or 5 hours we have the woman spend the night in the hospital where the operation was performed. She is kept comfortable with medications for discomfort and nausea. The nursing staff helps her get up and get moving. Less pain, less use of narcotics, and more movement in the first few days help minimize risks of problems like blood clots. I prefer to do operations that last 6 hours or less, but occasionally will do longer procedures on healthy patients who have great support at home. Mommy makeover procedures may create terrific results and outcomes for women, but safety is critically important. You really need to have great support at home for 5 or 6 days at least, you need to be in good health, and you should not be using any type of nicotine product, even e-cigarettes. Make sure that you feel like you surgeon is safe and ask her or him what she or he does to help keep you safe. Certainly complications can happen, but there's a lot at stake here and you need to do what you can to minimize your risks.
