When most people hear the term diastasis recti, they think of pregnancy and postpartum recovery. While diastasis recti is commonly discussed in women’s health, it can also occur in men—and often goes undiagnosed.
Many men are surprised to learn that a separation of the abdominal muscles can contribute to symptoms such as low back pain, core weakness, poor exercise performance, abdominal bulging, and even pelvic floor dysfunction.
As pelvic health physical and occupational therapists, we evaluate the entire pressure management system of the body, including the abdominal wall, diaphragm, core muscles, and pelvic floor. Understanding how these structures work together can be an important step toward improving function and reducing symptoms.
What Is Diastasis Recti?
Diastasis recti occurs when the connective tissue between the left and right sides of the rectus abdominis (commonly known as the “six-pack” muscles) becomes stretched, resulting in a widening or separation between the muscles.
Contrary to popular belief, this is not a muscle tear.
Instead, it is a change in the connective tissue called the linea alba, which serves as an important structure for force transmission throughout the abdominal wall.
When the linea alba loses tension or integrity, the core may become less efficient at generating and transferring force.
Can Men Develop Diastasis Recti?
Absolutely.
Common contributors to diastasis recti in men include:
- Significant abdominal weight gain
- Obesity
- Rapid weight fluctuations
- Chronic coughing
- Heavy lifting with poor pressure management
- Repeated straining
- Connective tissue disorders such as hypermobility syndromes
- Previous abdominal surgeries
Some men first notice a bulge down the middle of their abdomen when sitting up, performing a crunch, or lifting heavy objects.
Others may have no visible signs at all but experience symptoms related to impaired core function.
The Connection Between the Core and Pelvic Floor
One reason diastasis recti is relevant to pelvic health is that the abdominal wall does not function independently.
The core is often described as a pressure-management system made up of:
- The diaphragm at the top
- The abdominal muscles in the front and sides
- The spinal stabilizers in the back
- The pelvic floor at the bottom
These structures work together to manage pressure during activities such as:
- Lifting
- Coughing
- Exercising
- Bowel movements
- Daily movements
When one part of the system is not functioning efficiently, other structures may be forced to compensate.
How Diastasis Recti May Affect the Pelvic Floor
Many people assume that pelvic floor dysfunction only affects women, but men can experience pelvic floor symptoms as well.
When abdominal pressure is poorly managed, the pelvic floor may be subjected to increased demands during daily activities.
Potential symptoms can include:
- Urinary leakage
- Urinary urgency or frequency
- Constipation
- Difficulty emptying the bowels
- Pelvic pain
- Groin discomfort
- Feelings of weakness or instability during exercise
Not everyone with diastasis recti will develop pelvic floor dysfunction, but the two conditions often influence one another.
Why Traditional Core Exercises Can Sometimes Make Things Worse
A common response to noticing abdominal separation is to perform more sit-ups, crunches, or aggressive abdominal exercises.
Unfortunately, these strategies may increase pressure within the abdomen and place additional strain on the abdominal wall if performed without proper coordination.
The goal is not simply to make the abdominal muscles work harder.
The goal is to help the entire pressure-management system work more effectively.
This often includes:
- Breathing retraining
- Core coordination
- Pressure management strategies
- Functional strengthening
- Movement pattern assessment
Signs You May Benefit From an Evaluation
Men with diastasis recti may notice:
- A visible abdominal bulge
- Difficulty engaging the core
- Persistent low back pain
- Reduced exercise performance
- Hernia history
- Pelvic floor symptoms
- Feelings of instability during lifting
Because these symptoms can develop gradually, many individuals assume they are simply part of aging or deconditioning.
In reality, they may reflect an opportunity for targeted rehabilitation.
How Pelvic Health Therapy Can Help
Pelvic health physical and occupational therapists evaluate how the diaphragm, abdominal wall, pelvic floor, and movement patterns work together.
Treatment may include:
- Assessment of abdominal wall function
- Breathing and pressure-management training
- Core strengthening progressions
- Pelvic floor coordination
- Functional lifting mechanics
- Exercise modifications
- Education on bowel and bladder health
The focus is not solely on closing the gap between the abdominal muscles. Current evidence suggests that improving function, tension generation, and force transfer is often more important than achieving a specific measurement.
The Takeaway
Diastasis recti is not just a postpartum condition—it can affect men as well.
When the abdominal wall, diaphragm, and pelvic floor are not working together efficiently, symptoms such as core weakness, back pain, exercise limitations, constipation, and pelvic floor dysfunction can develop.
The good news is that rehabilitation can help. Through individualized assessment and treatment, pelvic health physical and occupational therapists can help improve coordination, strength, pressure management, and overall function.
If you’ve noticed abdominal bulging, persistent core weakness, or pelvic floor symptoms, it may be worth considering whether diastasis recti is contributing to the problem. Addressing the entire system—not just the abdominal muscles—can often lead to meaningful improvements in both performance and quality of life.
