Seroma or Normal Swelling 15 Weeks After Tummy Tuck?

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.

Thank you for your question,
While swelling after tummy tuck is very common I recommend you meet with your board certified plastic surgeon with any post op concerns you have so they can examine you in person and address them. 
Best Of Luck!

Either is possible 15 weeks following a tummy tuck (or many similar operations that involve elevating tissues from there normal attachments, aka - dissecting between tissue planes).  The only way to tell for sure is by physical exam (preferably by the operating surgeon who knows exactly what he/she did in surgery) and occasionally ultrasound to verify a seroma.
