Diastasis Recti After Pregnancy: How to Check and Exercises That Help

Months after delivery, many mothers feel that their tummy still looks pregnant, or notice a ridge or dome running down the middle of the belly when they sit up from lying down. Some also have back pain, a weak feeling in the core, or trouble lifting their baby comfortably. One common reason is diastasis recti, a widening of the gap between the two sides of the front tummy muscles.

The good news is that diastasis recti is very common, and many women see real improvement with the right exercises and daily habits. This guide explains what it is, how to check for it, what to do and what to avoid.

What is diastasis recti?

The rectus abdominis, often called the six-pack muscle, has a left and right side joined in the middle by a band of connective tissue called the linea alba. During pregnancy, the growing baby stretches this tissue and the two sides move apart. This is a normal adaptation, and almost all women have some separation by the end of pregnancy.

After birth, the gap usually narrows over the following weeks and months. In some women, the gap stays wider or the connective tissue stays soft and stretchy, which makes the tummy feel weak and less supportive. Factors that may increase the chance include multiple pregnancies, twins, a large baby, pregnancies close together, and lots of straining during heavy lifting.

How to check for a tummy gap at home

Wait until at least a few weeks after delivery, and longer after a C-section, until your wound has healed and your doctor is happy. This is only a rough self-check; a physiotherapist can assess it more accurately.

1. Lie on your back with knees bent and feet flat on the bed.
2. Place your fingertips across the middle line of your tummy, just above the belly button, fingers pointing towards your feet.
3. Gently lift your head and shoulders slightly off the bed, as if starting a small curl-up.
4. Feel for the edges of the muscle on each side. Note how many fingers fit in the gap and how deep your fingers sink.
5. Repeat at the belly button and a few centimetres below it.

Also look for a doming or ridge down the middle of the tummy when you sit up, cough or lift. The depth and firmness of the tissue matter as much as the width. A narrow gap that is soft and deep may need as much work as a wider gap with firm tension.

Daily habits that protect your tummy

• Roll to get up: instead of sitting straight up from lying, roll onto your side and push up with your arms. This avoids doming and strain.
• Breathe out when lifting: exhale gently and lightly draw in your lower tummy as you lift your baby, a bucket or a laundry basket.
• Watch your posture while feeding: sit supported with a pillow under the baby, rather than leaning forward for long periods.
• Avoid straining on the toilet: drink enough water, eat fibre and use a small footstool to raise your knees.
• Support when coughing or sneezing: gently support the tummy with your hands in the early weeks.

Exercises that help

Start these only once your doctor is happy with your recovery. After a normal delivery, gentle breathing and pelvic floor work can often begin within days; after a C-section, start more slowly. Your physiotherapist will tailor the plan to your gap and your body.

1. Diaphragmatic breathing with core connection

Lying on your back with knees bent or on your side, place your hands on your lower ribs. Breathe in through your nose so the ribs widen. As you breathe out, gently lift the pelvic floor and draw your lower tummy in towards your spine. Hold for 3 to 5 seconds, then relax. Repeat 10 times, 2 to 3 times a day.

2. Heel slides

Lying on your back with knees bent, connect your core as above. Slowly slide one heel along the bed until the leg is nearly straight, then slide it back, without letting your back arch or tummy dome. Repeat 8 to 10 times on each leg, 2 sets.

3. Pelvic tilts

Lying on your back with knees bent, breathe out and gently flatten your lower back into the bed by tilting your pelvis, then relax. Repeat 10 times.

4. Bridge

Lying on your back with knees bent and feet hip-width apart, breathe out, connect your core and lift your hips until your body forms a straight line from shoulders to knees. Hold for 3 seconds and lower slowly. Repeat 10 times, 2 sets.

5. Side-lying leg lifts and four-point kneeling

Side-lying leg lifts (10 each side) strengthen the hips. In four-point kneeling, gently connect your core and hold for 5 breaths without letting the tummy sag. Later, you can progress to lifting one arm forward at a time, 8 to 10 each side.

Stop if: you see doming or bulging down the middle of your tummy during an exercise, feel pain in the tummy, scar or back, notice leaking urine or a heavy feeling in the vagina, or feel dizzy. Go back to an easier level and ask your physiotherapist for guidance.

Exercises to avoid in the early stages

• Full sit-ups and crunches
• Double leg raises lying on your back
• Front planks held for long periods before your core can control them
• Heavy lifting with breath holding
• Intense twisting movements

These are not banned forever. As your strength and control improve, many women gradually return to them under guidance. The goal is to load the tummy in a way it can handle, not to avoid all challenge.

What about belts and binders?

Some women find a postnatal support belt comfortable in the early weeks, especially after a C-section. A belt can offer support but does not strengthen muscles on its own. Use it as advised by your doctor or physiotherapist, alongside exercise, and avoid wearing it very tight for long hours.

How long does it take to improve?

Many women notice better core control and comfort within a few months of regular exercise. The gap may narrow, though not always completely, and that can be fine if the tummy is strong and functional. If you still have a large gap, significant symptoms or a bulge at the belly button after a good period of physiotherapy, your doctor may refer you to a surgeon for an opinion.

When to see a doctor urgently

• A painful, firm bulge near the belly button or scar that does not go back in
• Redness, heat, discharge or opening of a C-section wound
• Fever, severe tummy pain or heavy bleeding
• Pain and swelling in one calf, or chest pain and breathlessness
