Rectus Diastasis (Muscle Separation)

Rectus Diastasis (Muscle Separation) occurs when the paired rectus abdominis muscles spread apart, widening the connective tissue called the linea alba that runs down the middle of the abdomen. It is most commonly seen after pregnancy, significant weight change, or abdominal surgery and may cause a visible midline bulge, reduced core strength, back discomfort, or a sensation of weakness; diagnosis is usually made with a physical examination and, in some cases, imaging such as ultrasound or CT to measure the separation.

Management starts with conservative measures like targeted physical therapy, core strengthening, and guidance on activity modification, which can improve function and symptoms for many people; surgical repair is considered when separation causes persistent functional problems or when a patient desires anatomic correction for comfort or appearance. Surgical approaches often involve plication of the rectus muscles and may be performed alongside abdominoplasty; recovery varies by technique and individual health, and long-term success is supported by progressive rehabilitation and lifestyle measures to protect the abdominal wall.
