Roundness of the abdomen weeks after a previously flat tummy tuck result can be the result of:
- loose abdominal wall
- pseudo bursa/seroma
Your description of increasing and decreasing roundness especially after eating is fairly indicative of loose abdominal wall. It may be that the sutures that were placed loosened or dissolved and the abdominal wall tightening has loosened. If this is the case a full tummy tuck revision will be needed to gain access and re-suture the abdominal wall.
All the best,
