A relatively common and easy-to-treat complication that can arise after surgery, a seroma is a pocket of fluid that builds up around the incision site. Seromas are more common after a tummy tuck than some other procedures, so surgeons often use drains to keep too much fluid from accumulating. Seromas can also be treated through aspiration, where a needle is used to remove the fluid.
Blisters can arise after tummy tuck surgery for a few reasons. Sometimes they are caused by sutures that irritate the skin, and sometimes surgical tape can be the source. The blisters usually heal on their own, but patients should always contact their surgeons if they have questions or concerns.
