Could Over Exertion be Causing Post Tummy Tuck Swelling?

The answer is YES, swelling of the lower abdomen will be present six weeks and longer after traditional tummy tuck, and YES, this swelling may be exacerbated by increased physical activity.  In agreement with other responders, you should see your surgeon to be sure the "swelling" is not actually a seroma.  If the swelling and lower abdominal fullness is fluctuant or enlarging, it is likely seroma.  An ultrasound study will definitively differentiate swelling from seroma.

Thank you for the question.

It would probably be best for you to be seen by your plastic surgeon again to rule out abnormal fluid accumulation (seroma).

Generally speaking,  tummy tuck surgery involves the interruption of arterial inflow as well as venous/lymphatic outflow. As patients' activity level increases  the abdominal wall flap may have a hard time eliminating fluids from the area. It may take several months to a year for the situation to improve  whereby patients no longer have the increased swelling with increased activity.

I have seen some significant tissue swelling that may be alarming but has always resolved with time.

I hope this helps.
