Diastasis recti is a common physical change that occurs during pregnancy, characterized by the separation of the rectus abdominis muscles, often referred to as the “six-pack” muscles. This separation happens along the linea alba, a band of connective tissue that runs down the midline of the abdomen. The condition represents a natural adaptation within the body to accommodate the expanding uterus and the growing fetus.
Understanding Diastasis Recti in Pregnancy
Diastasis recti develops due to physiological changes in pregnancy. As the uterus expands to make space for the developing baby, it exerts increasing pressure on the abdominal wall. This pressure causes the naturally elastic linea alba to stretch and thin.
This stretching allows the rectus abdominis muscles to move apart from each other at the midline. It often becomes noticeable during the second or third trimester, as the uterus reaches a significant size. This separation is a normal part of pregnancy, allowing the abdominal cavity to enlarge without injury.
Visual Signs and Appearance
A recognizable sign of diastasis recti during pregnancy is a noticeable “doming,” “ridging,” or “bulging” along the midline of the abdomen. This bulge becomes apparent when abdominal muscles are engaged, such as when sitting up, coughing, or straining. The appearance resembles a small ridge or mound protruding down the center of the stomach.
The extent and prominence of this bulge can vary significantly among individuals, depending on the degree of muscle separation and the amount of underlying abdominal pressure. This visible ridge often extends from just below the sternum, down past the navel, or it might be concentrated primarily around the navel area. The gap can feel soft and pliable to the touch, indicating the stretched connective tissue rather than firm muscle.
How to Identify Diastasis Recti
A simple self-assessment can help identify potential diastasis recti. Lie flat on your back with knees bent and feet flat. Place one hand behind your head for support, and with the other hand, place your fingertips firmly on your belly button, pointing towards your pelvis.
Gently lift your head and shoulders slightly, as if performing a small crunch, keeping your chin tucked towards your chest. As you lift, feel for a gap or indentation along the midline of your abdomen, both above and below your navel. If you feel a distinct separation, you can estimate its width by counting how many fingertips fit into the gap. This “finger-width test” indicates the extent of separation, serving as a self-assessment rather than a definitive medical diagnosis.
When to Consult a Healthcare Provider
While diastasis recti is common in pregnancy, consulting a healthcare provider is sensible for confirmation and guidance. An obstetrician, midwife, or specialized physical therapist can assess the abdominal separation. This evaluation helps determine the extent of the condition and rule out other concerns.
Evaluation is advisable if the separation is wide or accompanied by other symptoms. These symptoms might include persistent lower back pain or signs of pelvic floor dysfunction, such as urinary leakage. A healthcare provider can offer personalized advice and recommend appropriate strategies for managing the condition during and after pregnancy.
