Do permanent sutures ever get rejected from the body as they are a foreign substance?

I use a combination of permanent and absorbable sutures for the diastasis repair.  Other surgeons will have preferences based upon their experience.  Trust your board certified plastic surgeon to perform the surgery and oversee your post-operative care.

All suture types come with a price that the body must pay. Permanent sutures are not 'rejected' in the immunologic sense, but can erode through adjacent tissues, either above or below the sutures. Absorbable (non-permanent) sutures may not hold for long enough for a good tissue bond to form, and they may also cause an inflammatory reaction that causes its own problems.In my diastasis repair, I use both types of sutures, because this has given me the best results over the last thirty years. Hope this helps.
