In short
In rectus diastasis, the connective tissue between the rectus muscles becomes wider and thinner, often after pregnancy or major weight change. It is not itself a hernia, although diastasis and abdominal wall hernias can occur together. Treatment decisions are based more on function and symptoms than on a single measurement.
Rectus diastasis itself is not an emergency. If a coexisting hernia suddenly becomes hard, very painful and cannot be reduced — especially with nausea or vomiting — seek emergency care.
What happens at the examination
The assessment covers abdominal wall function, the width and length of the diastasis, and whether an umbilical or epigastric hernia is present. We also discuss previous exercise and the problems you want to address.
- Examination at rest and during activation
- Assessment for a coexisting hernia
- Review of functional symptoms
- Individual recommendation
Treatment options
The most suitable treatment is decided after an individual medical assessment.
After treatment
A gradual return to activity is required after abdominal wall surgery. You receive an individual plan for pain relief, wound care, support and loading. Recovery is longer than after a minor outpatient procedure.

Frequently asked questions
Is rectus diastasis the same as a hernia?
No. In diastasis the connective tissue is widened but not perforated. A hernia involves an actual defect in the abdominal wall.
How is rectus diastasis measured?
Width and length are assessed clinically and sometimes with ultrasound or CT. Function and any coexisting hernia matter more than one measurement alone.
What symptoms can it cause?
Possible symptoms include reduced core stability, abdominal doming, discomfort during loading and altered body image. Not everyone with a diastasis has symptoms.
Does rectus diastasis always require surgery?
No. Many people improve with adapted exercise. Surgery is considered for selected patients with persistent and relevant symptoms.
When can surgery be considered?
When structured rehabilitation has not provided sufficient improvement and symptoms remain significant, or when a coexisting hernia requires treatment.
Do you assess postpartum abdominal separation?
Yes. We assess abdominal wall function, the diastasis and any coexisting hernia.
Can an umbilical hernia be treated at the same time?
Yes, in selected cases the diastasis and an umbilical or epigastric hernia are planned as one reconstruction.
Is mesh used during surgery?
Mesh reinforcement may be appropriate when a hernia is present or for selected reconstructions. The method depends on anatomy and risk.
Will I need imaging?
Not always. Ultrasound or CT can be useful when a hernia is suspected, after previous surgery or when anatomy is complex.
How long is recovery after surgery?
This varies according to the method and extent of surgery. You receive an individual plan once treatment has been decided.
