DR after pregnancy refers to diastasis recti, a condition where the two sides of your abdominal muscles separate along the midline of your belly. It affects roughly half of women shortly after delivery, and about 30% still have it at one year postpartum. The separation isn’t a tear or a hernia. Instead, the connective tissue running down the center of your abdomen stretches and thins out during pregnancy, leaving a gap between the left and right sides of your “six-pack” muscles.
What Actually Happens to Your Abs
A band of connective tissue called the linea alba runs vertically down the center of your abdomen, holding the left and right sides of your rectus abdominis muscles together. It’s made of collagen fibers arranged in an interwoven lattice, and it’s designed to be strong. During pregnancy, hormonal changes soften this tissue while the growing uterus pushes the muscles apart. In many women, the linea alba stretches and thins so much that it can’t hold the muscles in their normal position after delivery.
The key distinction: diastasis recti is not a hole in your abdominal wall. There’s no true fascial defect. The bulge you see is simply the thinned-out connective tissue stretching under pressure. That’s why it looks different from a hernia, though the two can sometimes occur together.
How to Tell If You Have It
The most recognizable sign is a visible bulge or “pooch” above or below your belly button that persists even after you’ve lost pregnancy weight. Other common signs include:
- Coning or doming when you contract your abs, lean back in a chair, or sit up from lying down
- A soft, jelly-like feeling in the space between your left and right ab muscles
- Low back pain from weakened core support
- Difficulty with everyday tasks like lifting objects or walking comfortably
- Poor posture that wasn’t an issue before pregnancy
You can do a basic self-check at home. Lie on your back with your knees bent and place three fingers horizontally across your midline, just above your belly button. Tuck your chin and lift only your head (not your shoulders) until you feel your ab muscles engage. You should feel the edges of the muscles press against your fingers. Check three spots: at the belly button, about three finger-widths above it, and three finger-widths below it. Note how wide the gap is and whether the tissue underneath feels firm or squishy.
Clinicians generally use a gap of 2 centimeters (roughly two finger-widths) as the threshold for a diagnosis. But the width of the gap isn’t the whole picture. How much tension you can generate in that midline tissue matters just as much. A narrow gap with no tension can be more of a problem than a wider gap that feels firm when you engage your core.
Who Is Most at Risk
Any pregnant person can develop diastasis recti, but certain factors raise the odds. A higher BMI before or during pregnancy is a significant risk factor. Having multiple pregnancies increases risk at nearly every stage postpartum, and carrying twins raises the likelihood further, particularly in the first few years after delivery. Diabetes is also an independent risk factor, with effects that show up especially in the long term, at 20 and 30 years postpartum.
The Pelvic Floor Connection
Your abdominal muscles and pelvic floor work as a team to manage pressure inside your torso. When the abdominal wall is weakened by diastasis recti, it disrupts that coordination. The pelvic floor muscles may compensate by staying in a state of higher tension, which sounds helpful but actually impairs their ability to function normally.
Research shows that women with moderate to severe diastasis recti have significantly higher resting tension in key pelvic floor muscles, including those that control the urethra. This helps explain why diastasis recti often comes alongside pelvic floor problems like urinary leaking, pelvic organ prolapse, pain during sex, and hip or pelvic pain. These aren’t separate, unrelated issues. They share a common root in the disrupted pressure system of the core.
How Recovery Works
The gap narrows on its own for many women in the first weeks and months after delivery. Just over half of women have a measurable separation at six weeks postpartum, and by 12 months that number drops to about 30%. A three-finger-wide gap at three weeks postpartum is common and not a cause for alarm. The tissue is still recovering.
For women whose separation persists, targeted exercise is the first-line approach. The goal isn’t to force the muscles back together. It’s to retrain your deep core muscles so they can generate tension across the midline and support your trunk properly. The muscles that matter most here are the transverse abdominis (the deepest layer of your abs, which wraps around your torso like a corset), the pelvic floor muscles, the diaphragm, and small stabilizing muscles along your spine.
A simple starting exercise: lie on your back with knees bent, place your fingers on your lower abdomen, and as you exhale through pursed lips, gently squeeze your pelvic floor muscles while drawing your belly button in and up. You should feel tension build under your fingertips. Hold for five seconds, then release. This type of deep core activation has the strongest evidence for reducing diastasis recti symptoms.
Exercises to Approach With Caution
Traditional ab exercises like crunches and sit-ups can push your organs against the thinned linea alba, making the bulge worse. Planks are another exercise that may create too much pressure inside your abdomen. If you attempt a plank and notice coning along your midline, feel excessive pressure in your belly, or can’t breathe normally during it, that’s a clear signal to stop or modify. Switching to a plank on your knees or with your hands elevated on a chair or wall can reduce the load. If even that causes coning, skip planks entirely and focus on the deep core work instead.
The general rule: if any movement causes the center of your stomach to dome or bulge outward, that exercise isn’t appropriate for you right now. It doesn’t mean it’s off-limits forever, just that your core can’t manage the pressure it creates yet.
When Surgery Becomes an Option
Most women recover well enough with exercise alone or with guidance from a pelvic floor physical therapist. Surgery is typically considered when the separation is severe, symptoms are significantly affecting daily life, and conservative treatment hasn’t helped.
The most common surgical approach combines diastasis repair with an abdominoplasty (tummy tuck), where the surgeon stitches the stretched connective tissue back together and removes excess skin. For women with a very wide gap, greater than 5 centimeters, the tissue may be too thin to hold stitches reliably, so a mesh reinforcement placed behind the muscles may be used instead. Women without excess skin who want the diastasis addressed alone can sometimes opt for a less invasive repair.
A related but distinct procedure, panniculectomy, removes a large overhanging fold of skin that causes rashes, pain, or difficulty walking. Unlike abdominoplasty, it’s considered a functional surgery and may be covered by insurance. It does not typically include repair of the diastasis itself.
