Rectus diastasis
Understand separation of the abdominal muscles, common after pregnancy.
Editorial publication · Medical review pending.
Understand
Rectus diastasis is widening of the midline tissue between the two rectus abdominal muscles without a true hernia opening.
Possible symptoms
A midline bulge may appear when sitting up, with core weakness, discomfort or difficulty during some activities; many people have no pain.
Causes and associated factors
Pregnancy, major abdominal stretching, obesity, repeated strain, chronic constipation, hypermobility and ageing can contribute.
Diagnosis
Assessment reviews onset, symptoms, impact and expectations, examines the area and checks for a medical cause that should be treated first.
Tests
Tests are not routine; imaging, blood tests or specialist review are selected when a change is new, painful, asymmetrical or unusual.
Course of the condition
After childbirth the gap often narrows naturally over the first weeks or months but may persist.
Care options
Education, pressure management and progressive physiotherapy are priorities; surgical repair is mainly considered for lasting functional problems or an associated hernia.
When to consult
Seek assessment if the concern persists, affects function or strongly affects wellbeing, to discuss benefits, limits, alternatives and risks.
Urgent help
Sudden abdominal pain, vomiting or a hard lump that cannot be pushed back suggests a complicated hernia rather than simple diastasis and needs emergency care.
