Abdominal wall separation during pregnancy

The paired abdominal muscles move farther apart as the uterus grows and the connective tissue between them lengthens. A central ridge may become visible when sitting up, coughing or lifting, but its appearance alone does not show how well the abdominal wall functions.

Diastasis recti is not the same as the abdominal muscles tearing. The midline tissue becomes wider and thinner while the muscles remain on either side. You may notice doming, a feeling of reduced support, or discomfort with loaded movement; some pregnant people have a visible separation without pain.

A localized lump can instead be a hernia, especially if it is tender or does not flatten when you relax. A maternity clinician or physiotherapist can examine the area and review back, pelvic girdle or pelvic floor symptoms that may affect movement.

Breathe out through effort, turn onto your side to rise from lying, and keep carried objects near your body. Modify any exercise that causes pain, strong midline doming, pelvic pressure or loss of comfortable breathing. Supported strength work and walking may continue when they feel comfortable and fit your maternity care advice.

Avoid repeatedly testing the gap or forcing the abdomen flat. A pregnancy-trained physiotherapist can help adjust posture, lifting and trunk exercises now, then reassess recovery after birth when early tissue changes have had time to settle.

Mention persistent abdominal pain, a new focal bulge, or movement difficulty at your next maternity review. Seek urgent maternity or emergency advice for sudden or severe abdominal pain, vaginal bleeding, fluid leaking from the vagina, regular painful tightenings, faintness, fever, reduced fetal movement, or a hard painful bulge with vomiting.

Ask which exercises and lifting techniques suit your pregnancy, whether a focal bulge needs a hernia check, and when postnatal reassessment would be useful. Also describe pelvic heaviness, urine leakage, back pain or constipation so the advice can address the whole pressure-management system.
