You can check for diastasis recti at home with a simple physical self-test that takes about two minutes. While no online quiz replaces a professional evaluation, walking through a combination of the finger-width test and a checklist of common signs will give you a solid idea of whether your abdominal muscles have separated and whether it’s worth following up with a physiotherapist.
The Physical Self-Check
This hands-on test is the same basic method clinicians use during an initial screening. Lie on your back with your knees bent and your feet flat on the floor. Lift your head and shoulders slightly off the ground and look down at your stomach. Place the tips of your fingers just above your belly button, pointing downward toward your feet, and press gently into the midline of your abdomen. You’re feeling for a gap or softness between the two vertical bands of muscle that run down the center of your stomach.
Now turn your fingers sideways to measure the width of that gap. One finger width is roughly normal. Two finger widths is borderline. A gap of about two and a half finger widths (roughly 2 centimeters) or more at the belly button is generally considered diastasis recti. Repeat the test at two more spots: about three finger widths above your belly button and three finger widths below it. The separation can be wider in one area than another.
Pay attention to depth, too. If your fingers sink in deeply with little resistance, the connective tissue between the muscles has stretched significantly. A shallow gap with firm tissue underneath is a milder presentation, even if the width seems notable.
Visual and Physical Signs to Look For
Beyond the finger test, your body offers other clues. Work through this checklist and note how many apply to you:
- Abdominal bulge or “pooch”: A rounded protrusion just above or below your belly button that persists even after weight loss.
- Coning or doming: A visible ridge or tent shape that pops up along your midline when you contract your abs, sit up in bed, or lean back in a chair.
- Jelly-like softness: A squishy or hollow feeling around the belly button when you engage your core.
- Lower back pain: Persistent aching in your low back, especially during activities that require core stability like carrying groceries or picking up a child.
- Difficulty with everyday tasks: Struggling to lift objects, get up from a chair, or walk comfortably in ways that feel new or unusual.
- Poor posture: A sense that your trunk doesn’t support you the way it used to, with your pelvis tilting forward or your shoulders rounding.
- Pelvic floor issues: Leaking urine when you sneeze, cough, or jump. Diastasis recti frequently occurs alongside pelvic floor dysfunction.
If you found a gap of two or more finger widths and checked off two or more items on this list, there’s a reasonable chance you have diastasis recti. One sign alone, like a small belly pooch, doesn’t confirm it. But a measurable gap plus functional symptoms like back pain or urinary leaking paints a clearer picture.
Who Is Most at Risk
Pregnancy is the most common cause, but not the only one. A large study of postpartum women in China identified several factors that independently raise risk. Women who have had three or more deliveries face about 2.7 times the likelihood compared to first-time mothers. Carrying a baby weighing 3.5 kilograms (about 7.7 pounds) or more at birth increases risk by roughly 2.4 times. Gaining 15 kilograms or more during pregnancy (about 33 pounds) was also linked to higher rates.
Age matters as well. Women aged 30 to 39 and those over 40 showed higher proportions of moderate to severe separation compared to women in their twenties. A higher BMI before or during pregnancy was associated with more severe cases. And forceps-assisted deliveries were linked to worse outcomes, while vaginal delivery without instruments was actually associated with lower risk compared to cesarean delivery.
Men, people who have never been pregnant, and those who do heavy lifting or high-pressure core exercises can also develop diastasis recti, though it’s far less studied in those groups.
Does It Close on Its Own?
In many cases, yes, but there’s a window. The most significant natural recovery happens during the first eight weeks after delivery. After that point, spontaneous closing tends to plateau. Some research suggests the muscles may still be slowly recovering at six months postpartum, but by 12 months, about 36% of women still have a measurable separation. If your baby is older than a few months and the gap hasn’t narrowed, it’s unlikely to resolve completely without targeted work.
What a Professional Assessment Adds
The finger test gives you a rough estimate, but ultrasound imaging is the preferred tool for precise measurement. It allows a physiotherapist or clinician to measure the exact distance between the two muscle edges at multiple points along your midline, down to the millimeter. This matters because clinical thresholds vary by location: a gap wider than 20 millimeters at the belly button, wider than 14 millimeters just above it, or wider than 2 millimeters below it each qualify as diastasis recti under ultrasound criteria.
A professional can also assess the tension and integrity of the connective tissue itself, not just the width of the gap. Two people with the same gap width can have very different functional outcomes depending on how well that tissue transfers force. This is something you simply can’t feel with your fingers at home.
Exercises That Make It Worse
If your self-check suggests a separation, the most important immediate step is knowing what to avoid. Any movement that causes your abdominal wall to bulge forward can widen the gap. This includes crunches and sit-ups of any kind, standard planks and push-ups, double leg lifts, scissors, and certain yoga poses like downward dog and boat pose.
Even everyday movements can aggravate it. Sitting straight up out of bed, for example, puts direct pressure on the midline. Rolling to your side first and pushing up with your arm takes the load off. The same goes for getting up from a low chair or the floor. Any time you see or feel that doming or coning shape along your midline during a movement, that’s your signal to stop and find an alternative way to do it.
What Recovery Looks Like
The first-line approach is targeted rehabilitation, typically guided by a pelvic floor physiotherapist. This involves retraining the deep core muscles to generate tension across the midline without pushing the gap apart. The exercises look nothing like traditional ab workouts. They’re subtle, focused on breathing patterns and gentle engagement, and progressively build over weeks to months.
For the majority of people, consistent rehabilitative exercise narrows the gap or, more importantly, restores enough tension to the connective tissue that symptoms like back pain and instability resolve. Surgery is generally reserved for cases where the separation is severe (typically 3 centimeters or wider), functional impairment persists despite months of dedicated rehab, or there’s an associated hernia. The procedure involves stitching the muscle edges back together and is sometimes combined with pelvic floor repair.
If your self-assessment pointed toward a separation, getting a professional measurement gives you a clear baseline. From there, a physiotherapist can tell you exactly how wide the gap is, whether the tissue is functional, and what your specific recovery plan should look like.
