Diastasis recti is the separation of the two vertical abdominal muscles that pregnancy pushes apart to make room for the baby. It is common: a study following first-time mothers found it in 60 percent at six weeks after birth and still in about a third at twelve months. It causes the bulge that exercise does not flatten, and it weakens the core. Surgical repair, almost always as part of a tummy tuck, stitches the muscles back together. Dr. Itay Wiser explains the self-test, what exercise can and cannot do, the repair, and the honest insurance picture.
The self-test
- Lie on your back with knees bent and feet flat.
- Place your fingers, pointing down, on the midline just above the navel.
- Lift your head and shoulders slightly off the floor, as if starting a crunch, and feel for a gap between the two firm muscle edges.
- Measure the gap in finger-widths: two or more is a diastasis. Check again at the navel and a hand's width below it; the gap is often widest at the navel.
- Note whether the gap feels soft and deep (the tissue between the muscles is thin) or shallow; both matter for the plan.
The prevalence figures above come from a 2016 study in the British Journal of Sports Medicine that followed 300 first-time mothers to twelve months (Sperstad et al.). Dr. Wiser confirms the diagnosis by examination and, when the picture is unclear, ultrasound.
Diastasis recti: exercise versus surgery
Physical therapy and deep-core training are worth doing: they strengthen the muscles that support the abdominal wall, reduce the bulge, and help back and pelvic-floor symptoms. What they have not been shown to do reliably is close the separation itself. A 2021 systematic review found very low-quality evidence for exercise programs as a treatment for diastasis, and standard crunches can push the contents forward and make the bulge worse. When the gap is wide, or persists past a year with symptoms, surgery is the only repair, and the strengthening you did before makes the recovery better.
How the repair is done
During a tummy tuck, after the skin and fat are lifted off the abdominal wall, the two muscle edges are brought together and stitched along the midline from the breastbone to the pubic bone, restoring the wall's tension. The loose skin above is then removed and the navel repositioned. Repair alone, through a smaller incision, is reserved for the uncommon patient with a wide separation and little excess skin. The result is a flatter abdomen and a measurably stronger core; many mothers describe being able to sit up from lying down without rolling for the first time in years.
Insurance and diastasis repair
Coverage depends on your plan and your individual case. Some plans treat muscle repair on its own as cosmetic; Anthem's published policy is one example. When a hernia, a true gap in the abdominal wall, is present with the separation, its repair may be considered medically necessary and is done in the same operation. Dr. Wiser examines for a hernia at the consultation, and we're here to make the process easier. Our team can help answer insurance questions, take care of the necessary paperwork, and discuss available financing options to help make your procedure more accessible. The mommy makeover cost guide explains how a covered portion appears in an estimate.
Recovery and what changes
Recovery follows the tummy tuck timeline: two weeks of help, no heavy lifting until your surgeon clears you, to protect the repair, desk work in two to three weeks, exercise at six to eight weeks. The functional change is the part patients notice most: a core that holds, less back strain, and posture that improves without effort. Diastasis repair is usually part of a mommy makeover; the benefits article covers the functional side in more detail.
Frequently asked questions
How do I know if I have diastasis recti?
Lie on your back with knees bent, lift your head and shoulders slightly, and press your fingers into the midline just above the navel. A gap you can fit two or more fingers into is a diastasis. Dr. Wiser confirms it by examination and, if needed, ultrasound.
Can exercise fix diastasis recti?
Exercise can strengthen the deep core and reduce the bulge, and it is worth doing, but a systematic review found very low-quality evidence that exercise programs close the separation. Crunches can make the bulge worse. When the gap is wide or persists past a year, surgery is the only repair.
Is diastasis repair done alone or with a tummy tuck?
Almost always as part of a tummy tuck, because closing the muscles without removing the loose skin above them leaves the skin hanging. Repair alone is reserved for patients with little excess skin.
Does insurance cover diastasis recti repair?
It depends on your plan and your individual case. Some plans treat muscle repair alone as cosmetic, while a hernia repaired in the same operation may be covered. Our team reviews your plan, takes care of the paperwork and discusses financing options.
What does recovery involve?
The same as a tummy tuck: help at home for the first weeks, no heavy lifting until Dr. Wiser clears you to protect the repair, a gradual return to desk work and then exercise, with a noticeably stronger core afterward. Recovery timelines vary depending on the patient, the procedure and individual healing.
