Diastasis Recti: Understanding Abdominal Separation After Pregnancy
Pregnancy places significant stress on the abdominal wall, making diastasis recti one of the most common postpartum conditions. Many women notice a gap or bulge in the middle of their abdomen after childbirth, but few understand why it occurs or how it should be treated.
Although a mild separation is expected during pregnancy, persistent diastasis recti can contribute to core weakness, low back pain, pelvic floor dysfunction, poor posture, and difficulty returning to exercise. Fortunately, physiotherapy offers an evidence-based approach to restoring abdominal function and helping new mothers regain confidence in their movement.
What Is Diastasis Recti?
Diastasis recti is the separation of the two sides of the rectus abdominis ("six-pack") muscles due to stretching of the connective tissue known as the linea alba.
As your baby grows, the abdominal wall expands to accommodate the pregnancy. In some women, the connective tissue does not regain adequate tension after delivery, reducing the ability of the abdominal muscles to stabilize the trunk efficiently.
Recovery focuses on restoring abdominal function rather than simply closing the gap.
What Causes Diastasis Recti?
Several factors increase the likelihood of developing diastasis recti, including:
Pregnancy
Multiple pregnancies
Carrying twins or multiples
Large babies
Hormonal changes affecting connective tissue
Weak deep core muscles
Poor pressure management
Heavy lifting
Chronic coughing
Repeated straining from constipation
Although pregnancy is the most common cause, increased abdominal pressure may also contribute to diastasis recti in men and other populations.
Common Symptoms of Diastasis Recti
The symptoms of diastasis recti extend beyond an abdominal gap.
Common symptoms include:
Visible bulging or doming of the abdomen
Core weakness
Low back pain
Pelvic pain
Difficulty lifting
Poor posture
Feeling unstable during movement
Urinary leakage
Difficulty returning to exercise
Symptoms vary depending on muscle function, connective tissue integrity, and associated pelvic floor involvement.
How Physiotherapy Helps Treat Diastasis Recti
Physiotherapy is one of the most effective conservative treatments for diastasis recti.
A physiotherapist will assess:
Core muscle coordination
Linea alba tension
Breathing mechanics
Pelvic floor function
Posture
Hip and spinal mobility
Functional movement patterns
Treatment aims to restore strength, improve pressure management, and optimize whole-body movement.
Diastasis Recti Physiotherapy Exercises
Exercise is an essential part of recovering from diastasis recti, but performing the right exercises at the right time is critical.
Deep Core Exercises for Diastasis Recti
The transversus abdominis is retrained to improve spinal stability and abdominal support.
Breathing Exercises for Diastasis Recti
Diaphragmatic breathing helps regulate intra-abdominal pressure while improving core activation.
Pelvic Floor Rehabilitation for Diastasis Recti
The pelvic floor works together with the deep abdominal muscles to improve trunk stability and support functional movement.
Functional Strength Training for Diastasis Recti
Exercises are progressed gradually to prepare for lifting, carrying children, household activities, and returning to exercise safely.
Postural Training for Diastasis Recti
Improving posture reduces unnecessary strain on the abdominal wall and promotes more efficient movement patterns.
Can Exercise Make Diastasis Recti Worse?
Certain exercises can temporarily increase abdominal pressure if introduced too early.
These may include:
Sit-ups
Crunches
Double leg raises
Heavy lifting without proper core activation
Advanced planks before adequate control has been restored
A physiotherapist can determine when these exercises are appropriate during recovery.
When Should You See a Physiotherapist for Diastasis Recti?
You should consider an assessment if you experience:
Persistent abdominal separation
Core weakness
Low back pain
Pelvic pain
Difficulty lifting your baby
Doming during exercise
Urinary leakage
Difficulty returning to sports or fitness
Early intervention often leads to better long-term outcomes.
Can Diastasis Recti Heal Naturally?
Some improvement may occur naturally after childbirth.
However, successful recovery depends on restoring muscle coordination, connective tissue tension, breathing mechanics, and pelvic floor function—not simply reducing the width of the separation.
Many individuals continue to experience weakness despite the gap appearing smaller.
Tips for Recovering from Diastasis Recti
To support recovery:
Practice diaphragmatic breathing
Activate the deep core correctly
Improve posture
Use proper lifting mechanics
Avoid unnecessary abdominal pressure
Progress exercise gradually
Seek physiotherapy if symptoms persist
Small, consistent improvements are more effective than rushing back into intense exercise.
