diastasis recti
Pronunciation: die-AS-ta-sis REK-tie
Separation of the rectus abdominis muscles along the linea alba, commonly occurring during pregnancy and postpartum.
Full Definition
Diastasis recti is the separation of the rectus abdominis muscles at the linea alba, creating a gap between the left and right muscle bellies. This condition commonly occurs during pregnancy due to hormonal changes and mechanical stress from the growing uterus, affecting up to 60% of pregnant women. The separation typically becomes more pronounced in the third trimester and may persist postpartum. While often cosmetically concerning, diastasis recti can also contribute to core weakness, back pain, and functional limitations. Assessment involves measuring the width and depth of the separation, typically done at multiple points along the linea alba. Treatment may include physical therapy, exercise modification, and in severe cases, surgical repair.
Usage
Usage note: Distinguish from hernias; diastasis is muscle separation without fascial defect.
