How is rectus diastasis treated?
The rectus muscle edges are sewn together to eliminate the space caused by the stretched tissue in between. They must first be completely exposed by excising the excess lower abdominal skin and then raising the upper abdominal skin over the muscles as far as the ribs above. The muscles must be sewn together from top to bottom otherwise the abdomen will still bulge where they are not tightened (Figure 3, right). Several layers of permanent stitches are usually placed in order to maximally flatten the abdomen.
