Can I Get a Tummy Tuck While Awake?

Hi there-
I have personally done tummy tuck surgery under all possible anesthetic techniques, and would have you understand the following:
Doing a tummy tuck under local, it is almost impossible to achieve as good an outcome as you can reliably achieve with the patient under general anesthesia. Without muscle relaxation (medication given when under general anesthesia that paralyzes the muscles, making their tightening much more effective), effective muscle tightening is simply not possible as your muscles fight the sutures with every breath, especially if you feel a twinge of pain from time to time (this is inevitable).
If that's not enough to deter you, realize that THERe IS A LIMIT TO HOW MUCH NUMBING MEDICINE YOU CAN HAVE safely, and that if you have too much (because you are in pain and your surgeon is now under pressure to finish the operation he/she started), you could die. In fact, many of the cases of patient deaths during liposuction have resulted from overdoses of numbing medicine.
Tummy tucks can be done with deep sedation and numbing medicine, but again, the outcome is simply never as good.
Take a step back from this discussion for a minute and think about why you are even asking these questions.... I think it's probably safe to assume that you are asking about this because you want your abdomen to look as good as it can, and you would like to be as safe as possible throughout the process, right?
As long as that is the case, your chances of ending up happy are the highest if you find a surgeon certified by The American Board of Plastic Surgery and discuss your goals with them. For more on how best to find on you like and can trust, please read this:

A mini-abdominoplasty can be easily done under local. Doing a full abdominoplasty is a bit more work and would likely be uncomfortable under straight local. Doing it with some sedation or perhaps under spinal would be another alternative.

Anlost any procedure can be done under local anesthesia.  It may not be comfortable or pleasant, but it can be done.
Generally it is better to perform this procedure under general anesthesia because the airway can be protected from stomach contents, an unlikely but possible scenario.
