How Do You Get Diastasis Recti
Here's the thing — diastasis recti is one of those conditions that catches people completely off guard. You're pregnant, you're excited, you're maybe even feeling strong, and then someone mentions "abdominal separation" like it's inevitable. So what actually causes it? And can you reduce your risk? Worth adding: the short version is that diastasis recti happens when the connective tissue between your left and right abdominal muscles stretches and thins, causing them to separate. But the full story is more nuanced than that, and understanding how you get diastasis recti is the first step toward preventing it or addressing it early And that's really what it comes down to..
What Is Diastasis Recti
The Anatomy Behind the Separation
Your rectus abdominis — the "six-pack" muscle — runs vertically down the front of your torso. Left and right sides are connected by a band of connective tissue called the linea alba. In real terms, think of the linea alba as a sturdy zipper holding everything together. When that zipper gets pushed outward for too long or too hard, it stretches. In real terms, it thins. And eventually, the two sides of the muscle drift apart Small thing, real impact. Nothing fancy..
That separation is diastasis recti. It's not a tear. It's not a hernia. It's a widening of the space between the muscles, driven by the stretching and weakening of the connective tissue that binds them It's one of those things that adds up..
Who Gets It
Here's the uncomfortable truth — diastasis recti is extremely common. In real terms, studies suggest that up to 60% of women experience some degree of abdominal separation during or after pregnancy. Newborns can have it. Men can develop it. But it's not exclusive to pregnancy. People who do certain types of exercise incorrectly can trigger it too The details matter here..
The condition exists on a spectrum. Some people have a barely noticeable gap of a finger width or less. Others have a separation wide enough that their belly domes or cones visibly when they sit up from a lying position Simple as that..
Why It Matters / Why People Care
It's Not Just a Cosmetic Concern
A lot of people assume diastasis recti is just about how the belly looks. And yeah, for some people, the visual change is frustrating. But the functional side is what really matters. When the abdominal wall is compromised, your core can't do its job properly.
- Lower back pain becomes more likely because your abs can't share the load with your spine.
- Poor posture creeps in as your body compensates for the weakened midsection.
- Pelvic floor dysfunction can develop, leading to issues with bladder control or discomfort.
- Reduced stability in everyday movements — lifting, bending, even standing for long periods.
If you've ever heard someone say "I still look pregnant months after giving birth," diastasis recti is often the reason. The belly doesn't flatten out because the internal architecture has changed Still holds up..
The Emotional Side
Nobody talks about how disheartening it is to feel like your body betrayed you. You did everything "right" during pregnancy, and now your core feels different. That emotional weight is real, and it's part of why so many people search for answers about how diastasis recti happens in the first place But it adds up..
Some disagree here. Fair enough It's one of those things that adds up..
How It Happens: The Causes of Diastasis Recti
Pregnancy: The #1 Culprit
Let's start with the obvious. Pregnancy is the single biggest risk factor for diastasis recti, and here's why it makes sense biologically Not complicated — just consistent..
During pregnancy, your uterus expands dramatically. It pushes outward against the abdominal wall from the inside. At the same time, your body releases hormones — particularly relaxin and estrogen — that soften connective tissue. This is actually a brilliant design feature. Your body needs to be flexible enough to accommodate a growing baby, and eventually to allow the pelvis to open during delivery. But that same softening affects the linea alba, making it more prone to stretching beyond its normal capacity And that's really what it comes down to..
Real talk — this step gets skipped all the time.
The later into pregnancy you go, the more pressure builds. And with a second or third pregnancy, the tissue may not fully rebound from the previous stretch, which is why repeat pregnancies increase the risk.
Factors That Increase Your Risk During Pregnancy
Not every pregnant person develops diastasis recti, and not every case is severe. So what tips the scales?
- Carrying multiples. Twins, triplets, or more mean more internal pressure and more stretching.
- Having a large baby. A bigger baby means more room the uterus needs to expand.
- Being petite or having a small frame. There's simply less space for the baby to grow without pushing against the abdominal wall.
- Age. Older mothers may have less elastic connective tissue.
- Previous diastasis recti. If you had it in a prior pregnancy, the tissue is already compromised.
- Gaining weight rapidly during pregnancy, which adds to the internal pressure.
Abdominal Strain from Exercise
This one surprises people. You don't have to be pregnant to develop diastasis recti. Certain exercises place repeated, intense pressure on the abdominal wall.
- Crunches and sit-ups. These flex the spine against resistance, which pushes the abdominal contents outward against the linea alba.
- Heavy lifting done with poor bracing technique.
- Certain yoga poses that involve extreme extension of the spine, like deep backbends.
- High-impact activities performed without adequate core support.
The key issue isn't the exercise itself — it's doing it with poor form or without the core muscles properly engaged to protect the abdominal wall The details matter here. That alone is useful..
Weight Gain (Outside of Pregnancy)
Significant weight gain — whether from obesity, binge eating, or medical conditions — can put chronic pressure on the abdominal wall over time. The linea alba isn't designed to stretch indefinitely, and sustained pressure eventually takes its toll.
Fluid Accumulation and Medical Conditions
In rare cases, diastasis recti can be associated with conditions that cause fluid buildup in the abdomen, such as ascites (often related to liver disease). The increased intra-abdominal pressure pushes outward steadily, and the connective tissue gradually gives way Worth keeping that in mind..
Age and Hormonal Changes (Non-Pregnancy)
As people age, connective tissue naturally loses elasticity. So for older adults, diastasis recti can develop gradually without any obvious trigger. Hormonal shifts — especially during menopause — can accelerate this process. It's slow, it's subtle, and it often goes unnoticed until someone mentions a protruding belly that won't go flat.
Common Mistakes / What Most People Get Wrong
Thinking Only Pregnant Women Get It
This is the biggest misconception. But men, women who've never been pregnant, teenagers, and even babies can develop diastasis recti. Yes, pregnancy is the most common cause. If you have a persistent belly bulge that doesn't respond to diet or exercise, it's worth considering abdominal separation as a possibility.
Believing Crunches Will Fix It
Here's the irony — the exercises that can cause diastasis recti are often the ones people turn to to fix it. Crunches and sit-ups increase intra-abdominal pressure and can actually widen the separation. If you already
If you already think that crunches will close the gap, think again. Day to day, those same movements that helped create the separation are the ones that will keep it open. Instead of focusing on high‑impact flexion, aim for low‑load, co‑contraction exercises that teach the deep core muscles to work as a unified team.
The Right Way to “Fix” the Gap
- Engage the transversus abdominis – The deepest abdominal muscle wraps around the torso like a natural corset. By pulling the belly button toward the spine (a gentle “vacuum” action), you create intra‑abdominal pressure that supports the linea alba without forcing it outward.
- Activate the pelvic floor – A strong pelvic floor works in tandem with the transversus. Simple Kegel drills (contract for 3–5 seconds, relax, repeat 10–15 times) lay the foundation for a stable core.
- Practice the dead‑bug and bird‑dog – These moves encourage coordinated extension of the opposite arm and leg while maintaining a neutral spine. They teach the abdominal wall to resist pressure rather than push against it.
- Use a “belly‑button‑to‑spine” brace during daily activities – Whether you’re lifting groceries, bending to tie shoes, or sitting at a desk, a subtle inward pull of the navel can protect the midline.
- Progress gradually – Once the gap is reduced to less than two finger‑widths, you can slowly introduce light resistance (e.g., a light medicine ball or resistance band) but always prioritize form over load.
When to Seek Professional Help
- Gap larger than three finger‑widths after 12 weeks of consistent, guided exercises.
- Persistent lower back pain, pelvic floor dysfunction, or urinary leakage that doesn’t improve with basic core work.
- Any signs of hernia (visible bulge, pain when coughing, sudden onset of a lump).
A physical therapist specializing in pelvic floor or abdominal rehabilitation can perform a thorough assessment, prescribe a personalized program, and determine if you need referral to a surgeon.
Other Common Myths Debunked
| Myth | Reality |
|---|---|
| Only pregnant women get it | Diastasis recti affects people of all genders, ages, and body types. On the flip side, |
| If I lose weight, it will disappear | Weight loss reduces pressure but does not automatically close a widened linea alba. |
| It’s purely cosmetic | The condition can lead to core instability, posture problems, and chronic pain. Consider this: |
| Surgery is the only cure | Many cases respond to targeted exercise and manual therapy; surgery is reserved for severe or refractory cases. |
| All “core” exercises are harmful | Not all core work is problematic; low‑load, co‑contraction movements are safe and beneficial. |
Putting It All Together
Diastasis recti is a structural change that can stem from pregnancy, rapid weight gain, repetitive strain, medical conditions, or simply the natural aging process. The biggest obstacle is often the misconception that the same exercises used to cause the problem will fix it. By shifting the focus to deep core activation, proper bracing, and gradual, controlled movement, most people can achieve meaningful reduction in abdominal separation and alleviate associated discomfort That's the part that actually makes a difference..
Counterintuitive, but true Most people skip this — try not to..
If you’re ready to close the gap safely, start with a baseline assessment (a simple finger‑width measurement at the navel while lying down), then incorporate the low‑load, co‑contraction drills outlined above. Consistency, patience, and professional guidance are the three pillars that turn the journey from “I have a bulge” to “I have a stronger, stable core.”
Bottom line: Diastasis recti isn’t a life sentence of a protruding belly or chronic pain. With the right understanding, targeted rehabilitation, and realistic expectations, you can restore abdominal integrity and regain confidence in your body—whether you’re a new mom, a busy dad, a teen athlete, or anyone else seeking a healthier core.
