6 months post tummy tuck, is this swelling? (Photo)

Hello, it looks like your wounds are healing very very well. At 6 months there can indeed still be some swelling adjacent to an abdominoplasty incision. Sometimes it can take a while for the body to learn to "re-route" lymphatic fluid that is draining from the legs across the incision. Or some of this fluid can accumulate above the incision. Often abdominoplasties can continue to improve for a year after surgery. Sometime scar massage can help too. I would ask your surgeon how they want you to proceed with this. If, after a year things don't get to where you are happy, likely some small revision could be undertaken. On the whole it looks like you are doing very well.

Thanks for your question and the photos. It is still possible that you are swollen from surgery. Please speak to your surgeon about further concerns.
