Can You Get Hernias from Tummy Tuck?

Generally you do not get hernias from a tummy tuck but several situations can occur which can make a hernia seem to appear postoperatively.
A small hernia such as an umbilical hernia which was present prior to surgery but relatively undetectable can be more prominent postoperatively when the excess skin and fat are removed.
Separtion of the muscle repair postoperatively can occur and simulate a hernia as well.
There are many other potiential situations which can make a hernia appear postoperatively but this should not be an expected outcome of tummy tuck surgery.

I suppose anything is possible, but it's hard to imagine a hernia resulting from an abdominoplasty (tummy tuck).  Often hernias are encountered during the procedure and they are repaired.

Yes, You can get hernias from an abdominoplasty although it is unlikely. When dissecting the fat and skin off the anterior abdominal wall the anterior abdominal fascia can be violated leading to a post operative hernia. This would only occur if it was not recognized by the surgeon. An experienced surgeon knows what plane to be dissecting in and thus this should not occur.
