Is it normal after a tummy tuck to be short of breath when you try to walk?

Some shortness of breath is not uncommon following a surgery such as tummy tuck.  Bedrest, immobility, pain meds, etc. can attribute to some changes in activity tolerance.  However, severe shortness of breath coupled with lower leg pain could be a sign of serious concern such as a blood clot.  Best to let your plastic surgeon evaluate to be sure.

 Although shortness of breath may be “normal” after tummy tuck surgery, it may also be a sign of a postoperative complication (such as pneumonia or pulmonary embolism). Therefore, pulmonary concerns should be reported to your plastic surgeon who will be your best resource.  Best wishes.

you should let your surgeon know... because if its constant and you find yourself gasping for air (but you should be in an ER by now) it could be from clots forming in your legs and going to your lungs.  If its brief and following exertion that always goes away with rest, its probably nothing and reflects your inability to breathe with your tummy.  Still, when having breathing issues, always best to check with your surgeon to make sure its 'nothing'.
