Diastasis Recti & Postnatal Core

Diastasis recti is a widening of the gap between the abdominal muscles after pregnancy. Many women see it narrow naturally, and physiotherapy focuses on restoring deep core function and load control.

Understanding the condition

The gap is not the whole story.

Diastasis recti is a widening of the gap between the two halves of the rectus abdominis, the ‘six-pack’ muscle, caused by pregnancy stretching the connective tissue along the midline. Some separation is a normal response to pregnancy, and many women see it narrow over the first weeks and months.

What matters most is how well the core functions and controls load, rather than gap width alone. Signs include a ridge or doming along the belly when sitting up, a soft midline, low-back pain, pelvic heaviness or a weak core feeling.

Physiotherapy assesses the tissue and how well the deep core, diaphragm and pelvic floor work together, then builds breathing, deep core activation and progressive full-body strengthening, including clinical pilates. Surgery is only considered for severe cases with a hernia or persistent symptoms.

Why it happens

The root causes we look for.

01
Pregnancy
The growing uterus stretches the midline connective tissue.
02
Multiple or large pregnancies
More stretch and less time to recover between pregnancies.
03
Heavy straining or lifting early
Repeated high abdominal pressure can slow recovery of the midline.
04
Reduced deep core control
Poor coordination of the deep abdominals, diaphragm and pelvic floor raises strain.
Symptoms we treat

Recognise any of these?

A doming or ridge along the belly when sitting up
A soft gap felt down the midline
Low-back pain after pregnancy
A weak or 'unsupported' feeling core
Pelvic heaviness or leaks
Difficulty lifting or carrying
Our Approach

How we'll actually treat it.

STEP 1
1
Assess
Check the gap, tissue tension and how well the core controls load.
STEP 2
2
Breathe & connect
Breathing and deep core activation to restore the pressure system.
STEP 3
3
Strengthen & load
Graduated core, glute and full-body strengthening including clinical pilates.
STEP 4
4
Return to activity
Gradual return to running, lifting and gym work as control improves.
Services Involved

The disciplines we'll combine.

Every programme braids two or three of our core services. Here's the typical pairing for this condition.

The results

Treatment that actually holds.

A well-functioning core matters more than a closed gap, and structured, progressive work is what builds it.

Common questions

Your questions, answered.

Still unsure? Our clinicians answer the questions patients ask most. You can always call the HSR Layout clinic for a straight answer first.

Ask us directly
Many women see the gap narrow over the first few months, but function can remain weak, so a proper core programme is still useful.
Traditional crunches often aggravate doming early on. Graded deep core and full-body work is usually a better start.
It depends on your delivery and recovery, and gentle breathing and core activation can begin early. A physiotherapist can guide a graded return.
Only for severe cases with a hernia or symptoms that do not respond to rehabilitation.
