⚠️ Contact your surgeon if you notice warning signs after surgery

After a tummy tuck with muscle repair, contact your surgeon promptly if you experience increasing pain, swelling, redness, warmth, or drainage at the incision site, fever above 38C (100.4F), or new abdominal bulging. These could signal an infection, seroma (fluid collection), or other complication that needs prompt attention.

Short answer

Yes. A tummy tuck (abdominoplasty) commonly includes repair of diastasis recti, the separation of the two rectus abdominis muscles along the midline. The surgeon stitches the muscles back together in a step called plication, and research shows this improves both the appearance and function of the abdominal wall.

What the research shows

Diastasis recti (DR) is a condition where the two vertical abdominal muscles drift apart, stretching the connective tissue (linea alba) in between and causing a bulge in the belly wall. [1] Correcting this separation is considered one of the key goals of a successful abdominoplasty. [6]

During a standard tummy tuck, the surgeon brings the muscles back together with sutures, a step called plication. In cases of very severe separation, a mesh may be added for extra reinforcement. [7] A minimally invasive (endoscopic) version of the procedure can also repair the separation with smaller incisions, though it is best suited for patients who do not have a lot of loose skin. [2] [8]

What this means for you

Studies comparing the open tummy tuck approach to the endoscopic approach in 170 patients found that both are safe and effective options for repairing the muscle separation, with patient satisfaction guiding which approach is best for each individual. [3]

Beyond appearance, repairing the separation during a tummy tuck has been linked to real functional benefits. One prospective study of 51 women found a significant improvement in stress urinary incontinence (leaking with coughing or sneezing) one year after surgery. [5] A separate study of 37 women showed meaningful improvements in sexual function scores, core stability, and quality of life at the one-year mark. [4]

Important caveats

Not every tummy tuck automatically includes a muscle repair. Your surgeon will assess the degree of separation and the amount of abdominal bulging, because research shows that bulging of the abdominal wall is not always caused by muscle separation alone. [6] Some patients may have significant protrusion without much muscle separation, and vice versa.

For severe diastasis, additional reinforcement with a mesh may be needed. This is a less common step but has shown good results in small series of patients. [7] Always discuss your specific anatomy and goals with a board-certified plastic surgeon to understand which approach is right for you.

What to ask your surgeon

  • Do I have diastasis recti, and how wide is the separation?
  • Will muscle plication be included in my procedure, and with or without mesh?
  • Am I a candidate for a standard open tummy tuck or a minimally invasive endoscopic approach?
  • What functional improvements, beyond appearance, might I expect?
