Diastasis recti that won't close

How recovery typically progresses

Immediately after

First days

In the early postpartum weeks, a wide gap is close to universal and usually not a cause for concern on its own. This is the window for gentle core activation and letting swelling settle, not for judging whether the gap is closing yet.

Settling in

Early weeks

By a few months out, the gap has usually narrowed for most people but not fully closed, and research on this timeline finds the average distance keeps decreasing without ever fully returning to a pre-pregnancy baseline in the group studied. This is a reasonable point to start structured physical therapy if you have not already.

Longer arc

Beyond six weeks

Later in postpartum recovery, at six months and beyond, roughly four in ten people in one study still had a measurable gap. If yours has plateaued despite consistent physical therapy, that is when a surgical opinion becomes a reasonable next conversation rather than more waiting.

What does the evidence show for diastasis recti that won't close?

• In one study using digital calipers, diastasis recti was present in 90% of non-exercising women shortly after birth, still present in about 60% past the initial six-week recovery window, and still measurable in about 39% at six months, showing that a gap still open well past the early postpartum period is common rather than unusual. 1
• Tracked over time, the distance between the two sides of the abdominal muscle decreases gradually after birth, but in the population studied, baseline pre-pregnancy values were never achieved even by six-month assessments, supporting the experience of a gap that narrows without ever fully closing on its own. 2
• When a diastasis does not respond to conservative care and comes with discomfort, visible distortion of the abdomen during a muscle contraction, or an accompanying hernia, surgical options include midline plication of the connective tissue, plication reinforced with mesh for more extensive laxity, retrorectus repair for moderate to severe cases, and endoscopic techniques in select situations. 2
• Diastasis recti can resolve on its own without intervention, but that pattern is mostly seen in infants, where it is typically present from birth rather than caused by later stretching; in adults the gap more often persists and can call for further, more active management approaches. 3
• Manual palpation of the gap can under-read the true separation because subcutaneous fat and how relaxed the abdominal wall is both affect what a hand can feel, so before assuming a diastasis truly is not closing, an ultrasound measurement gives a more accurate number than a self-check alone. 4

A typical escalation timeline

When should I call my provider about diastasis recti that won't close?

A gap that has not narrowed by six months is common enough on its own that it is not, by itself, an emergency. What does need same-day attention is a bulge that turns firm, does not soften when you lie down and relax, or comes with real pain, since those signs separate a stalled diastasis from a true abdominal wall hernia, which carries a real risk of a trapped section of bowel. Sudden severe pain, nausea and vomiting alongside a bulge, or a lump that will not gently push back all call for care the same day rather than another week of waiting to see if it closes. Trust your read on your own body. If something feels off beyond the list above, please consult your healthcare provider rather than waiting it out.
