Tummy tucks are great for dealing with scars from previous surgery. Some of these scars that can be dealt with include a C-section, lower abdominal surgery from a hysterectomy, or even surgeries you've had in the past. There are some operations, however, that a tummy tuck will not be able to address, and that includes old-fashioned scars from gallbladder surgery or even traumatic surgeries where they've had to cut through the midline of the abdomen.
