Postpartum Diastasis Recti: Why Closing the Gap Takes More Than Time

A tent stands because its fabric holds even tension across every pole and seam. Loosen the tension on one section, and the whole structure sags in that direction, not because the fabric tore, but because the support underneath can no longer hold its shape. Your abdominal wall works as a similar tensioned structure, and diastasis recti, the separation between the two sides of your abdominal muscles that occurs during pregnancy, is that tension loosening at the seam running down the center.

Every pregnancy stretches this connective tissue seam to accommodate a growing uterus, and some degree of separation is a completely normal, expected part of pregnancy itself. What many new mothers are told, that this gap simply closes on its own within a matter of months after delivery, is true for some women and not for others, and there is no reliable way to predict in advance which category a given mother will fall into. For a meaningful number of women, the gap remains open a year, two years, or longer after birth, not because the tissue cannot heal, but because nothing has actively retrained the deep core system to generate the tension needed to bring that seam back together.

This is the part that time alone cannot do. A tent’s fabric does not retighten itself just because nobody touches it. Someone has to deliberately restore tension across the structure, and the same is true for the abdominal wall. Certain exercises, particularly ones that increase pressure straight through the midline without adequate deep core engagement, actually work against this process, widening the gap further rather than helping it close, which is part of why some women report their diastasis appears to worsen even while they are actively trying to exercise their way through it.

Assessing the Width, Depth, and Tension of Abdominal Separation

The first area to assess is the actual width and depth of the separation, along with whether the connective tissue at the gap can generate any tension at all when properly engaged, since this determines what kind of rehabilitation approach will actually help close it.

Restoring Deep Core Activation After Pregnancy

The second area is deep core activation technique, specifically learning to engage the deepest abdominal layer, the transverse abdominis, correctly and consistently, since this is the layer primarily responsible for drawing the separated muscles back toward the midline, and it is rarely engaged correctly without direct guidance and feedback.

Modifying Daily Movements and Exercises During Recovery

The third area is identifying and modifying which of a mother’s regular movements and exercises might be actively working against closure, since certain common exercises and even certain everyday movements, like how a woman gets up from lying down, can place pressure through the midline in a way that undermines the very healing being worked toward elsewhere.

A diastasis that has not closed on its own is not a permanent condition to simply live with. Reach out to us to arrange a session with Denny, our specialist in the Reconnect Method, who works specifically with postpartum core rehabilitation.
