Diastasis Recti: How to Fix “Mummy Tummy” Safely After Pregnancy

If you’ve noticed a persistent belly bulge or a vertical ridge down the center of your abdomen after childbirth, you may be experiencing diastasis recti. This common postpartum condition, often called “mummy tummy,” occurs when the abdominal muscles separate during pregnancy and don’t fully reconnect afterward.

The good news? Diastasis recti can be effectively treated through targeted exercises, physiotherapy, proper posture, and lifestyle modifications—helping you regain core strength and confidence without surgery in most cases.

Pregnancy is a beautiful journey, but it comes with physical changes that don’t always disappear after delivery. One of the most common yet misunderstood conditions new mothers face is diastasis recti, affecting approximately 60% of pregnant and postpartum women. Many women feel frustrated when their belly doesn’t “bounce back” despite diet and exercise efforts, not realizing that the underlying issue is a separation of the abdominal muscles that requires specific treatment.

What Is Diastasis Recti?

Diastasis recti (also called abdominal separation) is a condition where the two large parallel bands of abdominal muscles (rectus abdominis) separate along the midline of the abdomen. This separation occurs at the linea alba—the connective tissue that runs down the center of your belly.

During pregnancy, your body produces hormones like relaxin that soften connective tissues to accommodate your growing baby. Combined with the physical stretching from an expanding uterus, this can cause the abdominal muscles to separate. While some separation is normal during pregnancy, diastasis recti refers to when this gap doesn’t adequately close after delivery.

How to Know If You Have Diastasis Recti

The gap is typically measured in finger widths:

Normal: Less than 2 finger widths (about 2 cm)
Mild diastasis recti: 2-3 finger widths
Moderate to severe: More than 3 finger widths

Common Signs and Symptoms

Diastasis recti can manifest in various ways beyond just appearance:

A visible bulge or “pooch” in the middle of your abdomen, especially when sitting up or straining
A ridge or valley running vertically down your belly button
Lower back pain due to weakened core support
Poor posture and difficulty maintaining spinal alignment
Pelvic floor dysfunction, including urinary incontinence
Feeling of abdominal weakness or instability
Digestive issues like bloating or constipation
Difficulty performing everyday activities that require core strength

What Causes Diastasis Recti?

While pregnancy is the most common cause, several factors increase your risk:

Pregnancy-Related Factors:

Multiple pregnancies (twins, triplets)
Having babies close together
Pregnancy after age 35
Delivering a large baby
Excessive weight gain during pregnancy
Second or subsequent pregnancies

Other Contributing Factors:

Improper exercise techniques, especially heavy lifting without proper form
Chronic coughing or constipation
Obesity
Genetics and connective tissue disorders
Performing abdominal exercises incorrectly postpartum

How to Check for Diastasis Recti at Home

You can perform a simple self-assessment to check for abdominal separation:

Step-by-Step Self-Check:

Lie on your back with knees bent and feet flat on the floor
Place one hand behind your head for support
With your other hand, place your fingers (palm facing you) just above your belly button
Gently press your fingertips into your abdomen
Slowly lift your head and shoulders off the floor (like a small crunch)
Feel for a gap or separation between the two sides of your rectus abdominis muscle
Count how many fingers fit into the gap
Repeat the test just below your belly button and at the belly button level

What to Notice:

The width of the gap (number of fingers)
The depth of the gap (how far your fingers sink in)
The tension of the tissue (soft or firm)

If you detect a gap of more than 2 finger widths or notice symptoms like bulging or pain, it’s advisable to consult a physiotherapist specializing in postpartum care.

Can Diastasis Recti Heal on Its Own?

Mild cases of diastasis recti may improve naturally within the first 8-12 weeks postpartum as hormones normalize and your body recovers. However, many women need targeted intervention to achieve full recovery.

Without proper treatment:

The gap may remain permanently
Core weakness can worsen over time
You may experience chronic back pain
Future pregnancies can worsen the condition

Safe Exercises to Fix Diastasis Recti

Healing diastasis recti requires specific exercises that engage the deep core muscles without worsening the separation. Here are evidence-based exercises recommended by physiotherapists:

Phase 1: Early Postpartum (Weeks 1-6)

1. Diaphragmatic Breathing

Lie on your back with knees bent
Place one hand on your chest and one on your belly
Breathe deeply into your diaphragm, allowing your belly to rise
Exhale slowly, gently drawing your belly button toward your spine
Perform 10 breaths, 3-4 times daily

2. Pelvic Tilts

Lie on your back with knees bent
Gently rock your pelvis, flattening your lower back against the floor
Hold for 5 seconds and release
Repeat 10-15 times

3. Transverse Abdominal Activation

In any comfortable position, exhale and gently draw your belly button toward your spine
Imagine hugging your baby with your abdominal muscles
Hold for 5-10 seconds while breathing normally
Repeat 10 times

Phase 2: Progressive Strengthening (Weeks 6-12)

4. Modified Planks (Wall or Incline)

Start with hands against a wall, body at an angle
Keep your body in a straight line
Engage your core and hold for 10-30 seconds
Progress to lower angles as you get stronger

5. Heel Slides

Lie on your back with knees bent
Slowly slide one heel away from your body while keeping your core engaged
Return to starting position
Alternate legs for 10 repetitions each

6. Leg Lifts (Single)

Lie on your back with one knee bent, other leg straight
Keeping your core engaged, slowly lift the straight leg a few inches
Lower with control
Perform 8-10 repetitions per leg

Phase 3: Advanced Core Strengthening (3+ Months)

7. Bird Dog Exercise

Start on hands and knees
Extend opposite arm and leg while maintaining balance
Hold for 5-10 seconds
Return and switch sides
Perform 8-10 repetitions per side

8. Dead Bug

Lie on your back with arms extended toward ceiling
Lift knees to 90 degrees
Slowly lower opposite arm and leg toward the floor
Return and switch sides
Perform 10 repetitions per side

Exercises to AVOID

These exercises can worsen diastasis recti:

Traditional crunches and sit-ups
Planks (until you’ve built sufficient core strength)
Heavy lifting without proper form
Double leg lifts
Full push-ups on the floor
Any exercise that causes doming or bulging in your abdomen

Additional Treatment and Recovery Tips

Beyond exercises, these strategies support your healing journey:

1. Wear a Postpartum Support Garment

Abdominal binders or support belts can provide temporary support
Wear during activities, not 24/7
Choose breathable, adjustable options

2. Practice Proper Posture

Avoid slouching, which puts pressure on your abdomen
Engage your core when standing or sitting
Use pillows for support while feeding your baby

3. Be Mindful of Daily Movements

Roll to your side before getting up from lying down
Avoid heavy lifting in early recovery
Exhale during exertion
Keep loads close to your body

4. Manage Intra-Abdominal Pressure

Treat constipation promptly
Avoid straining during bowel movements
Manage chronic coughing
Maintain a healthy weight

5. Optimize Nutrition

Stay hydrated to support tissue healing
Consume adequate protein for muscle repair
Include collagen-supporting nutrients (vitamin C, zinc)
Eat fiber-rich foods to prevent constipation

6. Be Patient and Consistent

Recovery takes 6-12 months on average
Some cases may take longer
Consistency is more important than intensity
Celebrate small improvements

When to Consider Surgery

Most cases of diastasis recti improve with conservative treatment. However, surgery (abdominoplasty with muscle repair) may be considered if:

The gap remains larger than 3 finger widths after 12+ months of proper rehabilitation
You experience significant functional limitations
Conservative treatment hasn’t improved symptoms
You’ve completed your family and want surgical correction

Important: Always exhaust conservative options first, as surgery carries risks and doesn’t guarantee prevention of recurrence with future pregnancies.

Preventing Diastasis Recti in Future Pregnancies

If you’re planning another pregnancy, these strategies can reduce your risk:

Strengthen your core before conception
Maintain a healthy weight during pregnancy
Practice proper lifting techniques
Modify exercises as your pregnancy progresses
Work with a prenatal physiotherapist
Avoid exercises that cause abdominal bulging
Manage weight gain within recommended guidelines

Frequently Asked Questions

Q1: Can I exercise with diastasis recti, or will it make it worse?

Yes, you can and should exercise with diastasis recti, but it’s crucial to choose the right exercises. Focus on deep core activation exercises that engage your transverse abdominis muscle rather than superficial movements like crunches. Exercises that cause your abdomen to dome, bulge outward, or create a ridge down the middle should be avoided. Working with a physiotherapist ensures you’re performing exercises correctly and progressing safely. Many women worry that any exercise will worsen their condition, but proper exercise is actually the primary treatment for healing abdominal separation.

Q2: How long does it take to close a diastasis recti gap completely?

The timeline for healing diastasis recti varies significantly depending on the severity of separation, your consistency with exercises, overall health, and whether you have other contributing factors like obesity or chronic conditions. Mild cases may show improvement within 6-8 weeks, while moderate to severe cases typically require 6-12 months of dedicated rehabilitation. Some women may see functional improvement even if the gap doesn’t completely close—the quality and tension of the tissue matter as much as the width. It’s important to focus on regaining function and strength rather than obsessing over complete closure, as some women achieve excellent core function with a small remaining gap.

Q3: Will wearing an abdominal binder help close my diastasis recti faster?

Abdominal binders can provide temporary support and may help you feel more comfortable during daily activities, especially in the early postpartum period. However, they are not a standalone treatment and won’t “close” the gap by themselves. Think of them as training wheels—helpful for support while you’re building strength, but not a replacement for proper rehabilitation exercises. Wearing a binder should be combined with targeted exercises and physiotherapy. Additionally, you shouldn’t wear a binder 24/7, as your muscles need opportunities to work independently. Some research suggests they may help reduce pain and improve posture, but the primary treatment remains exercise and core strengthening.

Q4: Is it normal to still have diastasis recti years after giving birth?

Yes, it’s quite common for women to have unresolved diastasis recti years after childbirth, especially if they weren’t aware of the condition or didn’t receive proper treatment during the postpartum period. Many women don’t realize their persistent belly pooch is actually a treatable medical condition rather than just “stubborn fat.” The positive news is that it’s never too late to address diastasis recti. At Healyos Physiotherapy, we’ve successfully treated women 5, 10, or even 15 years postpartum. While healing may take longer if the condition has been present for years, significant improvement is still achievable with proper physiotherapy guidance and consistent exercise. Don’t let time pass discourage you from seeking treatment.

Q5: Can men get diastasis recti, or is it only a postpartum condition?

While diastasis recti is most commonly associated with pregnancy, men can develop it too, though it’s less common. In men, causes include obesity (particularly with rapid weight gain or loss), improper weightlifting techniques (especially with heavy loads and poor form), chronic coughing, or genetic factors affecting connective tissue. Newborns can also have diastasis recti, which typically resolves on its own. The treatment approach for men is similar to postpartum women—focusing on deep core strengthening, proper breathing techniques, and avoiding exercises that increase intra-abdominal pressure.
