Case Discussion

Diastasis recti abdominis (DRA) is not a true hernia, rather a thinning (rather than a defect of) the linea alba, which connects the recti abdominis muscles in the midline. Wide diastases cause a reduction of abdominal strength and may be associated with low back pain or midline abdominal pain 2. Symptomatic DRA is associated with reduced health-related quality of life 3. Diastasis recti abdominis is associated with true midline hernias due to thinning of the linea alba. The European Endohernia Society Guidelines classify DRA as mild: 2 to 3 cm; moderate: 3 to 5 cm; severe: >5cm 1.
