Diastasis recti only at the belly button: what to know

Diastasis recti is a thinning or widening along the tissue between the abdominal muscles. It can be more noticeable at the navel because that area is a natural point of pressure when you sit up, cough or lift. A ridge that appears with effort and softens when you relax can fit this pattern. A distinct lump at the belly button may instead be an umbilical hernia, so location alone cannot confirm the cause.

Pregnancy, changes in abdominal pressure, and previous abdominal surgery can affect the midline. The size of a gap does not by itself show how strong your core is or whether treatment is needed; comfort, function and the examination matter too.

Arrange an assessment with a clinician or pelvic-health physiotherapist if the change persists, causes discomfort, or affects lifting, exercise or daily movement. They may observe your abdomen during gentle movements and check the navel area. Until then, roll to your side before getting out of bed, breathe out during exertion, and avoid straining or breath-holding. Begin only exercises that feel controlled; forceful sit-ups can increase visible doming.

A tailored rehabilitation plan may address breathing, deep abdominal coordination and gradual return to loading. Read more about Postnatal Physiotherapy for guided support.

Seek urgent medical help for a belly-button lump that becomes very painful, firm, discoloured or difficult to push back, especially with vomiting or marked abdominal swelling. Contact a clinician soon for worsening pain, new bowel or bladder difficulty, or a bulge that remains prominent at rest. These features need assessment rather than home exercises.

Ask: Could this be diastasis recti, an umbilical hernia, or both? Which movements should I pause? Can you check my abdominal wall and guide a gradual strengthening plan? What symptoms should prompt urgent review?
