Postpartum diastasis recti typically looks like a visible bulge or “pooch” protruding just above or below your belly button, even after you’ve lost your pregnancy weight. But the appearance changes depending on what you’re doing. When you’re relaxed, it may just look like a soft, rounded belly that won’t flatten. When you strain, sit up, or lift something heavy, you may see a distinct ridge or dome shape running down the center of your abdomen.
What It Looks Like at Rest
When you’re standing or sitting normally, diastasis recti often shows up as a persistent lower belly pooch. This isn’t bloating or extra weight. It’s your organs pushing forward through the gap where your abdominal muscles have separated, with only a thin band of connective tissue holding things in place. The belly can look disproportionately rounded below the belly button, sometimes giving the appearance of still being pregnant months after delivery.
Some people also notice their belly button has changed shape, sometimes protruding more than it used to. In some cases, a small umbilical hernia develops at the site, which looks like a soft bulge right at the navel. The skin over the separation may appear loose or wrinkled, but that’s a separate issue from the muscle gap itself.
What It Looks Like When You Strain
The most telling visual sign appears when your abs are working. If you do a sit-up, lean back in a chair, or lift your baby from the floor, you may see a ridge or tent-like shape rising along the midline of your stomach. This is called coning or doming, and it’s the hallmark visual marker of diastasis recti. Instead of your abs pulling everything flat, the contents of your abdomen push outward through the gap between the two sides of your “six-pack” muscles.
Coning looks like a peaked ridge running vertically from your rib cage toward your pelvis. It’s easiest to spot during exercises like crunches or planks, or even during everyday movements like getting out of bed. If you see this shape appear whenever you brace your core, that’s a strong visual indicator of separation.
What It Feels Like to Touch
Diastasis recti isn’t just something you see. You can feel it too. If you press your fingers into the midline of your abdomen (between the two columns of muscle) while doing a small crunch, many people describe a soft, jelly-like texture in the gap. Instead of feeling firm muscle resistance, your fingers sink into a space where the connective tissue has stretched and thinned. The wider the gap, the deeper your fingers can press in.
This feel can range from a slight softness to a very noticeable lack of resistance. Some separations are narrow but deep, while others are wide but relatively shallow. Both the width and the quality of tension in that midline tissue matter for how your core functions overall.
How to Check Yourself
You can do a simple self-assessment at home. Lie on your back with both knees bent and feet flat on the floor. Place your index and middle fingers side by side just above your belly button, pointing down toward your feet. Slowly raise your head and shoulders off the floor (like a mini crunch) and feel for a gap or dip under your fingers. Then lower back down.
The gap is measured by how many fingers fit between the two muscle edges. One finger width or less is considered normal. A separation of two or more finger widths, roughly 2.5 centimeters or just under one inch, is generally considered diastasis recti. Some women have gaps of four or more finger widths. Repeat the test just below your belly button too, since the separation can vary along the length of the midline.
Symptoms Beyond Appearance
Diastasis recti isn’t purely cosmetic. Because the abdominal wall provides structural support for your entire trunk, a significant separation can cause lower back pain, a feeling of weakness or instability in your core, and difficulty with movements that require bracing (lifting, carrying, twisting). Some people also develop pelvic floor issues like leaking urine during exercise or sneezing, since the deep core muscles and the pelvic floor work as a connected system. A persistent feeling that your midsection is “unsupported” during daily activities is common.
How Recovery Works
Some degree of abdominal separation is nearly universal in late pregnancy, and for many people it narrows on its own in the first weeks and months postpartum. When the gap persists beyond that early recovery window, targeted rehabilitation can help. The modern clinical approach focuses less on “closing the gap” to a specific measurement and more on restoring functional tension in the connective tissue and reducing symptoms. Treatment success is typically measured by whether you feel stronger and whether the visible bulging and coning improve, not by whether the gap reaches some magic number.
Physical therapy focused on deep core retraining tends to be more effective for functional improvement (less back pain, better core control) than for purely cosmetic changes. A pelvic floor physical therapist can assess both the width of your separation and the tension quality of the tissue in between, which gives a more complete picture than finger width alone. For severe cases that don’t respond to rehabilitation, surgical repair is an option, but most people see meaningful improvement with consistent, guided exercise.
What to Watch For
Not every soft postpartum belly means diastasis recti. The key visual clues are: a pooch that persists well after delivery and weight loss, coning or doming during exertion, and a palpable gap wider than two fingers at the midline. If your belly looks relatively normal when relaxed but peaks into a ridge when you sit up or strain, that’s worth investigating. The combination of how it looks at rest, how it changes with movement, and how the midline tissue feels under your fingers gives you a reliable picture before you ever see a clinician.
