Fluid buildup or production after a tummytuck is going to happen most of the time. For this reason I like to use abdominal drains in combination to a supportive binder on the abdomen. The drains may be needed for 7 to 10 days or so.. There are some techniques that attempt to use a quilting suturing style that holds the skin down to the muscular structures below the skin. This has not worked as well for me in my practice. Limited activities, avoidance of antiinflammatories and aspirin, no driving of a car for two weeks, no straining, no lifting or excessive activities all help to minimize the possibility of bleeding or fluid buildup.
I would always follow the advice of your Plastic Surgeon when inquiring as to how to minimize the possibility of fluid formation.
Good luck to you.
