Stomach separation after birth: what to know

Stomach separation after birth often refers to diastasis recti, when the abdominal muscles are widened and the connective tissue between them is stretched. You may notice a ridge or doming along the midline when sitting up, reduced core support or back discomfort. A visible gap alone does not show how well the muscles function, so an assessment is more useful than repeated self-checking.

Pregnancy expands the abdominal wall, and the change can be more noticeable after multiple pregnancies, a large baby or a caesarean section, although it can happen after any birth. The separation may improve as tissues recover, while lifting, coughing or getting out of bed can make doming more obvious. It is separate from pre-eclampsia, which can cause concerning symptoms during or after pregnancy and needs medical attention.

Use a side-rolling movement to get out of bed, breathe out during effort and avoid straining while the area is tender. A postnatal physiotherapy assessment can check abdominal coordination, breathing, posture, pelvic-floor function and scar comfort, then build exercises gradually. Avoid forceful sit-ups or any movement that causes pain, marked doming or pressure. Progress should match healing, delivery details and your general health.

Arrange an assessment if the gap remains concerning, you have persistent back or abdominal pain, a bulge that is painful, or difficulty controlling urine or bowel movements. Seek urgent help for severe abdominal pain, fainting, fever, heavy bleeding, wound redness with spreading swelling or sudden shortness of breath. A clinician can distinguish muscle separation from a hernia or another problem.

Does my abdominal wall need a hands-on assessment? Which exercises are suitable at this stage? Could my scar, pelvic floor or back be contributing to symptoms? When can I safely lift, run or return to other activities?
