Rectus diastasis
What is rectus diastasis?
A separation of the rectus abdominis muscles along the midline, often noticed after pregnancy, weight gain or previous abdominal surgery.
Symptoms
- Visible midline bulge, especially with exertion
- Abdominal wall weakness or instability
- Lower back pain related to poor core support
- Pelvic symptoms such as prolapse or urinary issues
- Aesthetic concern after pregnancy or weight change
Diagnosis
Diastasis is diagnosed by clinical examination and dynamic ultrasound. The ultrasound measures the gap between the rectus muscles at rest and during contraction, and checks for associated hernias of the umbilicus or upper midline.
A complete assessment also evaluates the pelvic floor, posture, breathing pattern and any functional symptoms.
When to consider surgery
Surgery is considered when diastasis causes significant functional impairment, is associated with a hernia, or produces an aesthetic concern that does not improve with conservative measures. Conservative management is preferred for mild or asymptomatic cases.
