General anesthesia is a safe and comfortable option for tummy tuck, and I would not even think of doing it under local. Given the amount of tissue that would have to be numbed with local, that would likely be the riskier approach.
The mommy makeover is one of the best surgeries for changing someone's body in a dramatic way. It is a lot of surgery but commonly done together. There is no way to comfortably do that surgery under local anaesthetic. You would have to stage your procedures and even then may not get the comfort you need so your surgeon can do everything they want to give you the best result. The odds of anaesthetic problems in young healthy people is very low. I would discuss your concerns with your surgeon.Dr Rodger ShorttOakville Plastic SurgeonAssistant Clinical Professor &Director of Cosmetic Surgery Training Program,McMaster UniversityOakville, Burlington, Georgetown, Milton, Mississauga, Hamilton, and Toronto.
