Based on your photo, you look like you have some swelling above the level of the incision. I have seen swelling in the lower abdominal area that persists for up to 1 year after abdominoplasty. Alternatively, if your upper abdominal skin and fatty layer thickness was preoperatively thicker than your pubic/groin area thickness, it is not unusual to see a discrepancy, or step-off, when a surgeon sutures a thicker skin/fat layer to a thinner skin/fat layer. On a similar note, any stretch marks that were present above your umbilicus do remain but are now in a lower location on the abdominal wall. Skin loss can be a risk with central abdominal liposuction at the same time as tummy tuck, so I typically do not thin the central abdominal area during any abdominoplasty. I am sure your plastic surgeon will be able to advise you about whether it is swelling or fat. If it is fat, a second stage central abdominal liposuction procedure will improve the contours, however, expect financial obligation for additional procedures. I hope I addressed your concerns.
