Is this a disfigurement and why would it occur after abdominoplasty? (Photo)

Dear Lshaw143,
I understand your concern. However, without a proper assessment, it would be difficult to determine what is wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

This abdominal contour could be related to muscle wall laxity. If it was not corrected during surgery this could be the cause, or it could be that it failed after correction. It could also be related to visceral fat which is the fat around your organs behind your muscle wall. This is corrected through weight loss. I encourage you to see your surgeon for an evaluation of your concerns.

This kind of bulge is usually a result of weak abdominal muscles and remaining fat under the skin. Tummy tuck surgery is usually combined with liposuction to reduce the thickness of fat and if it is done agressively you may experience blood circulation problems and wound healing issues. My recommendation for you to do abdominal work out to strengthen your muscles. If you request a more fit look secondary liposuction will give you a better shape in a safe way.
