How common is diastasis recti?

The two sides of the rectus abdominis muscles are joined by a band of connective tissue. When that tissue stretches and the muscles move farther apart, the midline may look or feel soft, ridged, or domed when you sit up. The gap itself is not the same as a hernia, although both can be present.

Many people have no pain. Some notice reduced trunk support, difficulty coordinating the abdominal wall, back discomfort, or changes around the navel. Pregnancy places repeated stretch on the abdominal wall, but body size, connective-tissue characteristics, previous surgery, and pressure from lifting can also influence it.

A clinician or physiotherapist can assess the abdominal wall while you breathe, move, and gently tighten the core. Treatment usually focuses on coordinated breathing, gradual deep-core loading, posture, and movements that do not cause doming or pain. Avoid using a gap measurement alone to judge progress; comfort, control, and function matter too.

A tailored programme may be useful after pregnancy or when symptoms affect exercise and daily tasks. See [Postnatal Physiotherapy](/treatments/pelvic-floor-and-rehabilitation/postnatal-physiotherapy/) for rehabilitation support.

Arrange an assessment if a bulge is painful, firm, suddenly larger, or associated with vomiting, marked tenderness, or skin colour change. Seek prompt medical care for severe abdominal pain, faintness, or repeated vomiting. For a painless, stable midline change, a routine assessment can clarify whether it is diastasis recti or another abdominal-wall problem.

Ask whether the finding is diastasis recti, a hernia, or both; which activities need modification; how to progress core exercises; and whether back, pelvic-floor, or breathing symptoms are connected.
