Diastasis recti is a condition that involves a separation of the rectus abdominis muscles—the “six-pack” muscles that run down the front of the abdomen. This separation occurs along the linea alba, a connective tissue that helps support the core and transfer load through the trunk.

Diastasis recti most commonly develops during pregnancy and postpartum, but it can also affect athletes, individuals who perform repetitive core loading, and people who experience significant changes in abdominal pressure.

What Causes Diastasis Recti?

During pregnancy, the growing uterus increases pressure within the abdomen and places stress on the connective tissue of the core. Hormonal changes also make connective tissue more elastic, which allows the abdomen to expand but can contribute to separation.

Outside of pregnancy, diastasis recti can develop from improper core loading, chronic breath-holding, excessive abdominal pressure during exercise, or poor coordination between the diaphragm, deep core muscles, and pelvic floor.

Common Signs and Symptoms

Diastasis recti presents differently from person to person. Common signs include:

A visible bulge or doming along the midline of the abdomen

A “pooch” or soft area that doesn’t respond to traditional core exercises

Decreased core strength or stability

Low back pain or pelvic discomfort

Difficulty managing pressure during lifting or exercise

Diastasis recti is not simply a cosmetic issue. It can affect how force transfers through the body and influence movement, posture, and performance.

How Physical Therapy Treats Diastasis Recti

Physical therapy focuses on restoring function, strength, and pressure control rather than just closing the gap. Research shows that improving muscle coordination and connective tissue tension matters more than the width of the separation alone.

A physical therapy program for diastasis recti may include:

Education on posture, breathing, and pressure management

Training the deep core muscles, including the transverse abdominis

Coordinating the diaphragm, pelvic floor, and abdominal wall

Progressive strength training for the core and full body

Modifications to daily activities and exercise routines

Hands-on techniques and guided movement help retrain the core to work as a unit, supporting both healing and long-term strength.

Can Diastasis Recti Heal?

With appropriate guidance, many people see significant improvement in core strength, function, and symptoms. Early intervention often leads to better outcomes, but it is never too late to seek help. Physical therapy provides a safe, structured approach to rebuilding core strength without increasing strain or pressure.

When to Seek Help

If you notice abdominal bulging, persistent core weakness, or pain with daily activities or exercise, a physical therapist trained in core and pelvic health can assess your movement and create a personalized plan.
