New moms in Atlanta, Charlotte, Greenville, Knoxville, and across the Southeast often describe the same frustrating experience: they worked hard during pregnancy, followed their provider's advice postpartum, started exercising again, and yet something still feels off. The belly doesn't look right. Core exercises feel strange or cause discomfort. Lower back pain persists. They feel weak through the middle even though they're trying to strengthen it. In many of these cases, the underlying issue is diastasis recti, and the exercises being recommended are the exact ones that slow healing or actively make the separation worse.
What Diastasis Recti Actually Is
Diastasis recti (DR) is a separation of the two halves of the rectus abdominis muscle, the paired vertical muscles that run down the center of the abdomen. They're held together at the midline by a band of connective tissue called the linea alba. During pregnancy, as the uterus expands, the linea alba is stretched and the rectus muscles are pushed apart. This is a normal physiological adaptation, but the degree of separation and the quality of the linea alba tissue afterward varies significantly.
Research suggests that roughly 100% of women have some degree of diastasis recti at 35 weeks of pregnancy. The question is how much of it resolves, and how quickly, after delivery. Studies show that 39% of women still have clinically significant diastasis recti at six months postpartum. Without appropriate intervention, many continue to carry the separation for years.
The separation is measured in finger-widths at three points along the linea alba (above, at, and below the navel) and also assessed for tissue tension, because a wide separation with good tension can be more functional than a narrow separation with soft, lax tissue. Both width and tension matter for core function and stability.
Why It Matters Beyond Appearance
Diastasis recti is frequently framed as a cosmetic concern, and the "mummy tummy" appearance does bother many women. But the functional consequences are the more serious issue. The linea alba is part of the deep core canister that manages intra-abdominal pressure. When it's lax or significantly separated, the core system cannot generate and transfer force effectively. This has downstream effects throughout the body.
Persistent lower back pain is one of the most common symptoms associated with unaddressed diastasis recti, because the lumbar spine loses the dynamic stabilization the core normally provides. Pelvic floor dysfunction, including leakage, urgency, and pelvic organ prolapse risk, is also associated with diastasis recti because the pelvic floor and the deep core work as an integrated pressure management system. When the linea alba can't maintain tension, the pelvic floor takes compensatory load it wasn't designed to carry.
Postpartum women with undiagnosed diastasis recti often report that their core feels unreliable during lifting, that they have persistent lower back pain that doesn't respond to standard treatments, and that they feel as though something "pops out" in their abdomen when they sit up or strain. These are the signatures of a compromised core canister.
Exercises That Can Make Diastasis Recti Worse
- • Traditional crunches and sit-ups, which create a "doming" effect at the midline
- • Planks performed before adequate deep core activation is established
- • Double-leg lowering exercises that generate excessive intra-abdominal pressure
- • Heavy lifting without proper breath and bracing technique
- • Running or high-impact activity before the linea alba has adequate tension
The Pelvic Alignment Connection
What chiropractors bring to diastasis recti recovery that most fitness-based approaches miss is attention to the pelvic and lumbar structure underneath the core. The deep core muscles, specifically the transverse abdominis, pelvic floor, diaphragm, and multifidus, function most effectively when the pelvis and lumbar spine are in proper alignment. When the pelvis is anteriorly tilted, posteriorly tilted, or asymmetrically positioned, the resting tension of the core muscles is altered. The transverse abdominis can't engage properly. The pelvic floor is either constantly overworked or unable to activate effectively. And healing the linea alba becomes significantly harder because the mechanical environment it's healing in is never neutral.
Chiropractic adjustments restore normal pelvic and lumbar alignment, creating the structural foundation that makes deep core rehabilitation more effective. This is why many postpartum women who have worked with pelvic floor physical therapists for months and made limited progress see accelerated improvement when chiropractic care is added to address the underlying structural component.
What Postpartum Chiropractic Care Looks Like
At Postpartum Clinic Southeast, we begin with a comprehensive postpartum assessment that evaluates pelvic alignment, lumbar curvature, sacroiliac joint function, and core activation patterns. For patients with suspected diastasis recti, we assess the separation and coordinate with pelvic floor physical therapists when appropriate.
Treatment is phased to match the postpartum recovery timeline. In the early postpartum phase (typically six weeks onward with OB clearance), the focus is on gentle pelvic and lumbar alignment restoration and breath-based core activation. As recovery progresses, we add graduated loading that respects the healing linea alba and builds genuine core stability rather than compensation patterns.
We also educate patients on functional movement patterns for the demands of new motherhood, including how to safely lift a baby, how to get in and out of bed without increasing intra-abdominal pressure, and how to carry and wear an infant in ways that don't place additional strain on a recovering core.
With 13 locations across the Southeast, including Atlanta, Charlotte, Greenville, Knoxville, and Beaufort, Postpartum Clinic Southeast is the regional resource for new mothers who want structural care that addresses why they're not healing, not just exercises to work around it.
