Abdominal rectus muscle separation explained

It can follow pregnancy or other prolonged pressure on the abdominal wall. The muscles have not torn apart, and appearance alone does not show how well the trunk functions.

The linea alba, a band of connective tissue running down the midline, becomes stretched and transfers load less effectively. You may notice a ridge or doming when sitting up, a soft gap around the navel, reduced trunk control, or difficulty coordinating the abdomen during lifting.

A gap can exist without pain or disability. Conversely, a person with a modest visible gap may still have back discomfort, pelvic-floor symptoms, or trouble managing pressure. Assessment therefore considers tension, movement, breathing, strength, and daily function rather than width alone.

Begin with comfortable breathing and controlled abdominal engagement during everyday movements. Exhale during effort, roll onto your side to rise from bed, and reduce an exercise if it causes marked doming, pain, breath-holding, or pelvic heaviness. Gradual strengthening can include the trunk, hips, and pelvic floor.

Postnatal physiotherapy can check movement technique and tailor progression to your symptoms and goals. There is no single exercise that suits everyone, and avoiding all abdominal exercise can delay useful strength recovery.

Arrange an assessment if the separation is painful, daily tasks feel unstable, exercise repeatedly causes pronounced bulging, or you also have urine leakage, pelvic pressure, or persistent back pain. A clinician or physiotherapist can also distinguish diastasis from a hernia.

Seek urgent care for a new abdominal lump that becomes severely painful, firm, discoloured, or impossible to push back, particularly with vomiting or abdominal swelling. Those features may indicate a trapped hernia rather than uncomplicated muscle separation.

Ask how well the midline creates tension, whether a hernia is present, which movements need temporary modification, and how to progress lifting or exercise without worsening your symptoms.
