If you have noticed a gap, a ridge, or a bulge running down the middle of your tummy since pregnancy, you may have diastasis recti, a separation of the abdominal muscles. It is very common, it is not your fault, and for many women it improves significantly with the right, guided exercise rather than surgery.

When the Gap Does Not Close on Its Own
Some abdominal separation after birth is normal and narrows by itself in the first weeks. When it does not, ordinary exercise, and especially the wrong exercise, can make it look and feel worse. The answer is not to push harder but to retrain the deep core muscles in the right order.
How to Tell If You Have Diastasis Recti
Common signs include:
A visible gap or valley along the midline of your tummy
A ridge or doming that appears when you sit up or strain
A soft, bulging belly that does not respond to normal exercise
A weak core, or a feeling that your middle lacks support
Lower back pain or a sense of instability
A simple hands-on check during your assessment tells us how wide and how deep the separation is, which guides your programme.
Why the Abdominal Muscles Separate
The two halves of your outermost abdominal muscle are joined by a band of connective tissue called the linea alba. As your baby grows, this band stretches to make room, and the muscles move apart. In some women it stays stretched after birth. It can also develop from repeated heavy lifting with poor technique, or other causes of sustained pressure on the abdominal wall.
How Diastasis Recti Is Assessed
We confirm and measure the separation rather than judge it by appearance. Your assessment usually includes:
A hands-on check of the width and depth of the gap along your midline
Watching for doming or bulging when you gently tense your core
Checking how your deep core and pelvic floor work together
Ruling out other causes of a bulge where needed
A gentle finger-width self-check at home can give you a rough idea, but it is a starting point, not a diagnosis. The hands-on check tells us how firm the tissue is, not just how wide the gap is.
Our Treatment Approach
Measure first.
We assess the width and depth of the separation and how your core behaves under load.
Retrain the deep core.
You learn to activate the deep muscles correctly before we add any strengthening.
Progress safely.
We build load gradually and avoid movements that cause doming until you are ready.
Fix the everyday habits.
Posture, breathing, and lifting technique all affect the gap.
Know when to refer.
For a small number of women with a very large separation or ongoing symptoms, we will discuss a surgical opinion honestly.
Safe First Exercises, and What to Avoid
These deep-core exercises are a common, gentle starting point. They are general guidance rather than a diagnosis, so build up slowly and stop anything that makes your tummy dome or bulge.
Diaphragmatic breathing.
Coordinate your breath with a gentle deep-core draw-in.
Pelvic tilts.
Wake up the deep abdominal muscles without straining.
Gentle bridges.
Lift your hips while keeping the core engaged and the tummy flat.
Deep core holds.
Gently engage the deepest abdominal layer before adding any load.
For now, avoid traditional crunches, sit-ups, full planks, and heavy lifting, which can widen the gap. We reintroduce these safely once your core is ready.
The Difference Guided Rehab Makes
A flatter, stronger, more functional core. A tummy that feels supported rather than weak. Less back pain. And the confidence to return to exercise knowing you are not making things worse.
Do You Need Surgery for Diastasis Recti?
For most women, guided exercise is the first-line approach and can meaningfully reduce the separation and restore core strength. Surgery is usually considered only for a very large gap, an associated hernia, or symptoms that do not respond to a proper rehabilitation programme. We will assess you honestly and, if a surgical opinion is worth exploring, help you seek one.
How Long Recovery Takes
Diastasis recti improves gradually, usually over a few months of consistent work, and progress is measured by both function and the width of the gap, not by appearance alone. Results vary from person to person, and we will set realistic expectations after assessing you rather than promise a fixed outcome.
Keeping Your Core Strong Afterwards
To protect your progress:
Keep training the deep core, not just the surface muscles
Use good lifting technique and breathe out as you lift
Reintroduce demanding core exercises gradually
Manage constipation and avoid repeated straining
When to check with your doctor. See a doctor promptly if you notice a firm, painful, or growing bulge, or a lump that does not go back in, as this can suggest a hernia rather than a simple separation.
Questions
Frequently Asked Questions
Can diastasis recti heal without surgery?
For many women, yes. Guided exercise can meaningfully reduce the separation and restore core function. A minority with a very large gap may benefit from a surgical opinion, and we will tell you honestly which group you are likely in.
How do I know if I actually have it?
A quick physical check during your assessment is the reliable way to know, rather than guessing from photos online.
Are crunches and sit-ups bad for it?
Done too early or with poor control, they can worsen doming. We reintroduce them safely once your deep core is ready.
How long before I see a difference?
Many women notice improvement within a few weeks of consistent, correct exercise, with continued progress over the following months.
Can I check for diastasis recti at home?
A gentle finger-width check along your midline can give you a rough idea, but it is a starting point, not a diagnosis. A hands-on assessment measures the width and the firmness of the tissue accurately.
You do not have to live with a weak middle or avoid exercise out of fear. An assessment will show you exactly where you stand and what your programme should look like.
