The most effective thing you can do about diastasis recti is targeted deep core rehabilitation, which works for the majority of people and can meaningfully close the gap without surgery. A separation wider than 2 centimeters (roughly two finger-widths) is the clinical threshold for diagnosis, and that measurement is your starting point for tracking progress.
How to Check Your Own Separation
Lie on your back with your knees bent and feet flat on the floor. Place two or three fingers horizontally just above your belly button, pointing toward your toes. Slowly lift your head and shoulders off the ground as if starting a crunch. You should feel the edges of your abdominal muscles tighten on either side of your fingers. If two or more fingers fit in the gap between those muscle edges, you likely have diastasis recti. Repeat the test just below your belly button, since the gap can vary along its length.
Providers sometimes confirm this with ultrasound or calipers for a more precise measurement, but the finger-width test is a reliable first step. The gap itself matters, but so does the tension you feel in the tissue between the muscles. A two-finger gap with firm, springy tissue underneath is a better sign than a narrower gap with soft, slack tissue.
Why Deep Core Work Is the First-Line Treatment
The key muscle in diastasis recti recovery is the deepest layer of your abdominal wall, the transverse abdominis. This muscle wraps around your torso like a corset, and when it contracts, it pulls on the connective tissue (the linea alba) that runs down the center of your abdomen. That pulling action increases the stiffness and tension of the linea alba, drawing the separated muscles closer together. It also improves trunk stability, which is why people with diastasis recti often notice back pain improving as their deep core gets stronger.
The most commonly recommended starting exercises focus on learning to activate this deep layer without recruiting the more superficial muscles that can push the gap wider. These include:
- Diaphragmatic breathing with gentle core engagement: Inhale to expand your ribs, then exhale slowly while drawing your belly button toward your spine. This teaches you to find and activate the deep core muscles in isolation.
- Heel slides and toe taps: While lying on your back with your core gently engaged, slowly extend one leg at a time along the floor or lower one foot from a tabletop position. These add light load to the deep core without spiking pressure in the abdomen.
- Modified dead bugs: From a back-lying position with knees above hips, slowly extend one arm overhead or one leg away from you while maintaining a flat, stable torso.
A pelvic floor physical therapist is the best person to guide this progression. They can assess your specific gap width, tissue tension, and movement patterns, then tailor a program that advances as you get stronger. Most rehab programs run 8 to 12 weeks before a reassessment, though meaningful improvement can continue for months.
Movements to Avoid Early On
Exercises and daily movements that spike pressure inside your abdomen can push the gap wider or slow your progress. Traditional crunches and sit-ups are the most commonly cited culprits because they create a strong forward force that pushes the abdominal wall outward right at the separation point. Planks, push-ups, and heavy overhead lifts can have a similar effect if your deep core isn’t yet strong enough to manage the pressure.
This doesn’t mean these exercises are permanently off-limits. It means they belong later in the progression, once you’ve rebuilt enough deep core control to perform them without the tissue bulging or “doming” at the midline. If you see a ridge or cone shape forming along the center of your belly during any movement, that’s a sign the load is too much for your current level of core control.
In daily life, pay attention to how you get out of bed (roll to one side first rather than sitting straight up), how you pick up children or heavy objects (exhale and engage your core before lifting), and how you manage coughing or sneezing (brace your abdomen with a hand if needed). These small adjustments reduce repetitive strain on the connective tissue while it’s healing.
Abdominal Binders and Support Garments
Postpartum belly wraps and abdominal binders can provide temporary support and comfort, especially in the early weeks after delivery. They work by externally compressing the abdominal wall, which can make movement less painful and give you a sense of stability. What they do not do is permanently close the gap or replace exercise. Think of them as a helpful bridge while you build the internal muscle support to take over that job. If a binder feels good, use it, but pair it with a rehabilitation program.
The Pelvic Floor Connection
You’ll often see diastasis recti discussed alongside pelvic floor problems like urinary leakage and pelvic organ prolapse. The core and pelvic floor do work as a unit, and it makes sense to train them together. However, the relationship may be less dramatic than commonly assumed. A study published in BMC Women’s Health compared women with and without diastasis recti across multiple gap widths, from 20 mm to over 50 mm, and found no statistically significant difference in rates of urinary incontinence or pelvic organ prolapse between the groups. About 20% of women in both groups reported some urinary leakage regardless of whether they had a separation.
That said, if you do experience leakage, heaviness in the pelvic area, or difficulty controlling your bladder, bring it up with your provider. These issues are treatable on their own, and a pelvic floor therapist can address them alongside your diastasis rehab.
When Surgery Becomes an Option
Most people with diastasis recti will not need surgery. It becomes a consideration when a dedicated rehabilitation program has plateaued and you still have significant symptoms: persistent pain that worsens with movement, a visibly distorted abdominal wall, or a hernia at the midline. Umbilical hernias are particularly common alongside diastasis recti because the stretched connective tissue creates a weak point. Repairing a hernia without also addressing the surrounding diastasis often leads to recurrence, since the lax tissue can’t hold the repair.
Both open and minimally invasive (laparoscopic) surgical approaches are available. A pooled analysis of 56 studies found no significant difference between the two in complication rates or recurrence. Recurrence rates were low across the board, under 2% for both approaches. The most common complications were fluid buildup, minor bleeding, and infection, occurring in roughly 12% to 16% of cases regardless of technique. The choice between open and laparoscopic repair typically depends on the size of the separation, whether a hernia is involved, and your surgeon’s expertise.
Recovery from surgical repair generally involves several weeks of restricted activity, including no heavy lifting, followed by a gradual return to exercise. Your surgeon will give you a specific timeline based on your procedure.
Building a Practical Recovery Plan
If you suspect you have diastasis recti, a reasonable sequence looks like this: confirm the gap with the self-check described above, then get an assessment from a pelvic floor physical therapist or a provider experienced with abdominal wall conditions. Start a deep core rehabilitation program and commit to it consistently for at least two to three months before judging progress. Modify your daily movements to reduce unnecessary abdominal pressure. Use a support garment if it helps you stay comfortable and active.
Progress isn’t always a dramatic gap closure. For some people, the gap narrows significantly. For others, it narrows modestly but the tissue becomes much firmer, which restores function and eliminates symptoms even if you still measure a small separation. Functional recovery, meaning you can do what you want to do without pain or instability, is the more meaningful goal than chasing a specific number of finger-widths.
