Does repairing diastasis recti improve pelvic floor function?

Your diastasis is on the smaller side so it is likely that it can be repaired without a full tummy tuck. But I would not expect the diastasis repair to improve your pelvic floor function.

Insurance will not cover a pure diastasis repair, another option for repair of the muscles without a full tummy tuck is to do a modified mini tuck where the incision is about twice as long as a c-section scar, no incision around the belly button and minimal skin is removed. Through this incision your muscles can be fully repaired. In terms of pelvic floor function most likely the incontinence will improve but it is not a guarantee. The constipation will likely have no change that is more related to diet, hydration and many other factors but abdominal musculature is not one of them.

To my knowledge, a rectus diastasis repair does not influence pelvic floor dysfunction. What patients have occasionally reported is an improvement of their back pain, when undergoing a lipoaboominoplasty with rectus diastasis repair. Your symptoms need a different type of care and specialist. I hope this helps.
