Sneezing after abdominoplasty. Will it ruin my results?

Patients often cough and sneeze after abdominal surgery. This can be painful but will not affect the long-term results. If you anticipate sneezing or coughing place counter pressure on the abdominal wall to decrease the discomfort.

I would not worry about sneezing.  This is a normal activity of life and will not affect your tummy tuck.  Nonetheless, if you do have to sneeze, bring a hanky with you and perhaps try to sneeze with your mouth open (i.e. obviously away from others).  Closing your mouth during a sneeze can increase the back pressure internally on your abdomen.  Either way, I'm sure you will be fine.

Most abdominoplasties also have their muscle tightened. The biggest risk post op with sneezing is to pop one of these stitches. What I recommend -- is when you feel the sneeze coming on-- squeeze a pillow tightly on your abdomen before you sneeze.
Squeeze before you sneeze.

Sneezing after abdominoplasty, although rare, could cause enough pressure to break or tear some of the internal stiches, which are used to tighten your abdominal muscles. To be on the safe side open your mouth when you sneeze so as to lessen the strain on your stitches. Or you can sneeze into your arm so you will not spray everyone around you. If you have concern call your Surgeon and make an appointment to be checked.
