Understanding Diastasis Recti: What Every New Mom Should Know
You've just had your baby, and as you look down at your postpartum belly, you might notice something unexpected: a visible gap or ridge running down the center of your abdomen. Welcome to diastasis recti—and you're definitely not alone. This separation of the abdominal muscles happens to the majority of pregnant women, and while it's a completely normal part of pregnancy and birth, learning how to heal diastasis recti is one of the most important steps in your postpartum recovery journey.
👶 Try It: Postpartum Recovery Timeline
Diastasis recti occurs when the two sheets of muscle that make up your six-pack (the rectus abdominis) separate to make room for your growing baby. During pregnancy, the connective tissue between these muscles (called the linea alba) stretches and thins. After birth, that gap doesn't automatically snap back—it requires intentional, mindful work to repair.
Here's what you need to know right now: diastasis recti is not a failure of your body. It's not permanent. And with the right approach, most women see significant improvement within weeks to months postpartum. The key is understanding what your body needs and being patient with the healing process.
The Postpartum Timeline: When Does Diastasis Recti Heal?
One of the most common questions we hear from new moms is, "How long will this take?" The honest answer is: it depends on several factors, including the severity of your separation, your exercise routine, your genetics, and how soon you start targeted recovery work.
Week 1-6 Postpartum: The Initial Healing Phase
During the first six weeks after birth, your body is in survival mode. Your uterus is shrinking, hormones are fluctuating wildly, and you're sleep-deprived. This isn't the time for intense core work. Instead, focus on gentle movements, proper breathing, and allowing your body to heal. Your abdominal muscles need time to begin reconnecting, and pushing too hard too soon can actually worsen the separation.
Week 6-12 Postpartum: Building Your Foundation
Once you have clearance from your OB/GYN (typically around 6 weeks for vaginal birth, 8-12 weeks for cesarean), this is when you can begin more intentional diastasis recti healing work. You'll start introducing gentle core exercises that focus on functional strength rather than traditional crunches or sit-ups (which can actually increase abdominal pressure and worsen the gap). Many women see noticeable improvement during this 6-week window with consistent, proper exercise.
3-6 Months Postpartum: Progressive Recovery
By three months postpartum, if you've been consistent with your exercises and have proper form, many women notice significant changes in both the appearance and function of their core. The gap typically narrows, the ridge softens, and you start feeling stronger. This is an exciting phase where you can gradually progress to more challenging movements.
6-12 Months and Beyond: Long-Term Healing
Complete closure of diastasis recti can take up to a year or longer, but most functional improvement happens much faster. Some women never achieve complete closure—and that's okay. What matters is that your core functions properly, supports your daily activities, and doesn't cause pain or dysfunction. Even a small remaining gap with strong, functional muscles is far better than a closed gap with weak muscles.
Safe Exercises to Heal Diastasis Recti Postpartum
Let's talk about what actually works. The most effective approach to healing diastasis recti combines exercises that:
- Engage your deep core muscles (transverse abdominis)
- Maintain proper intra-abdominal pressure
- Build functional strength for daily mom activities
- Avoid excessive downward pressure on the healing tissue
Important reminder: Before starting any postpartum exercise program, consult with your OB/GYN to confirm you have clearance, especially if you had a cesarean delivery or any complications during birth. Consider working with a pelvic floor physical therapist who can assess your individual situation and provide personalized guidance.
Breathing Exercises: The Foundation
Before you do a single crunch (which you shouldn't, by the way), master your breathing. Proper breathing is the foundation of diastasis recti recovery. When you breathe correctly, you engage your deepest core muscles and maintain optimal pressure in your abdomen.
360-Degree Breathing: Lie on your back with knees bent. As you inhale, allow your ribcage to expand in all directions—front, sides, and back. As you exhale, gently draw your belly button toward your spine without holding your breath. This activates your transverse abdominis without creating excessive pressure.
Transverse Abdominis Engagement
Your transverse abdominis is like a corset around your midsection, and it's your secret weapon for diastasis recti recovery. Heel slides, dead bugs (modified), and standing marches all work this muscle effectively without stressing the linea alba.
Modified Dead Bug: Lie on your back with knees bent, feet on the floor. Slowly lift one foot off the ground while maintaining your neutral spine—no arching, no pressing your lower back into the floor. Lower it and repeat on the other side. This teaches your core to work in coordination with limb movement without excessive pressure.
Functional Movement Patterns
As you progress, focus on movements that mimic real life with your baby: picking up a car seat, carrying a toddler, or bending to pick up toys. These functional movements build strength that actually matters for your daily life as a new mom.

Lifestyle Changes That Support Diastasis Recti Healing
Exercise is crucial, but it's only part of the equation. How you move, breathe, and live throughout your day also impacts your diastasis recti recovery.
Modify Your Daily Movements
This is huge. The way you get out of bed, pick up your baby, or sit up from the couch matters. Avoid traditional sit-ups, crunches, or any movement that creates a doming or bulging in your abdomen. Instead:
- Roll to your side before sitting up in bed
- Engage your core before lifting anything heavy (like your car seat or toddler)
- Avoid high-impact activities initially
- Be mindful of your posture throughout the day
Support Your Core with Your Posture
Postpartum posture is often terrible—between sleep deprivation, nursing, and hunching over your baby, your spine is under stress. This increased forward rounding creates additional strain on your healing abdominal muscles. Focusing on standing tall, rolling your shoulders back, and engaging your core throughout the day actually supports your diastasis recti recovery.
Manage Intra-Abdominal Pressure
Anything that increases pressure in your abdomen (chronic coughing, constipation, heavy lifting before you're ready) can slow diastasis recti healing. Stay hydrated, manage any postpartum cough, and avoid straining. If constipation is an issue—which it often is postpartum—address it gently and naturally when possible.
Consider Your Pelvic Floor Connection
Your pelvic floor and your core work together as an integrated system. Many postpartum women need to address pelvic floor recovery alongside their diastasis recti healing. A weak or tight pelvic floor can actually prevent proper core engagement and slow your abdominal recovery. If you're experiencing pelvic pain, heaviness, or urinary incontinence, these are signs to seek professional pelvic floor PT.
What NOT to Do: Common Diastasis Recti Mistakes
Understanding what to avoid is just as important as knowing what to do. Here are the biggest mistakes we see new moms make:
Traditional Core Exercises (At First)
Crunches, sit-ups, and full planks are off-limits during early diastasis recti recovery. These movements increase intra-abdominal pressure and can actually widen the gap. Wait until your core is significantly stronger and you have professional clearance before progressing to these exercises.
Ignoring the Warning Signs
If you see doming or bulging in your abdomen during an exercise, stop immediately. That bulging is a sign that the pressure inside your abdomen is too great for your healing tissue to manage. Listen to your body—it's sending you important information.
Comparing Your Timeline to Others
Your best friend might have her gap close in 8 weeks while yours takes 6 months. Both are normal. Your genetics, the severity of your separation, your exercise consistency, and countless other factors influence your individual healing timeline. Trust your journey, not someone else's.
Expecting Results Without Consistency
Diastasis recti doesn't heal with sporadic effort. You need consistent, focused work—ideally 4-6 days per week of targeted exercises. This is why many moms find success with a structured postpartum app that guides them daily.
When to Seek Professional Help
While many cases of diastasis recti improve with home exercise, some situations benefit from professional guidance:
- Your gap hasn't improved after 12 weeks of consistent exercise
- You experience pain or dysfunction associated with your diastasis recti
- You have a very severe separation (gap greater than 2-3 finger widths)
- You're not sure if you're doing exercises correctly
- You have concurrent pelvic floor issues
A pelvic floor physical therapist can assess your specific situation and provide personalized guidance. They can also rule out other conditions and ensure your exercises are supporting—not hindering—your recovery. This professional guidance, combined with a structured postpartum fitness program, creates the ideal foundation for healing.
Nutritional Support for Core Healing
You can't out-exercise a poor diet. Your recovering body needs adequate protein to rebuild muscle tissue, sufficient hydration to support healing, and nutrient-dense foods to provide energy for the demanding work of caring for a newborn while recovering from birth.
Focus on anti-inflammatory foods, adequate protein intake, and staying hydrated. If you're breastfeeding, your nutritional needs are even higher. Check out our guide on breastfeeding and weight loss for more specific postpartum nutrition guidance.
FAQ: Your Diastasis Recti Questions Answered
Can diastasis recti get worse after pregnancy?
Yes, if you don't address it. Continuing to do traditional ab exercises, lifting heavy objects without core engagement, or ignoring postpartum recovery can maintain or even worsen the separation. However, with intentional recovery work, it improves in the vast majority of cases. The key is starting as soon as you have medical clearance and being consistent with your efforts.
Will another pregnancy make my diastasis recti worse?
It's possible, but not inevitable. Many women with a history of diastasis recti have second pregnancies without significant additional separation, especially if they've done the work to heal and strengthen their core between pregnancies. However, this is a conversation worth having with your OB/GYN or a pelvic floor PT before trying to conceive again.
Is surgery necessary for diastasis recti?
Rarely. Surgery is typically only recommended if you have diastasis recti combined with a hernia, or if you've completed conservative treatment with no improvement after a year or more and you have significant functional problems. The overwhelming majority of women see meaningful improvement through exercise, proper movement patterns, and time. Always consult your healthcare provider to discuss your specific situation.
Conclusion: Your Diastasis Recti Recovery Starts Now
Learning how to heal diastasis recti is one of the most empowering things you can do for your postpartum recovery. Your separated abdominal muscles aren't a permanent reminder of pregnancy—they're a natural part of your body's incredible journey, and with the right approach, they heal.
Remember: this is a marathon, not a sprint. Your body just did something extraordinary, and it deserves time, patience, and intentional care. Start with your doctor's clearance, focus on proper breathing and core engagement, avoid the exercises that increase pressure, and stay consistent with your recovery routine.
