How to Spot Ab Muscle Separation and Stomach Bulges in Women
A midline bulge can be one visible sign of abdominal muscle separation, also called diastasis recti. It is a reason to check the whole midline, not proof of a diagnosis by itself.
What to notice
The bulge may look like a ridge or dome down the center of the belly during a sit-up motion, cough, or strain. It may be more obvious in one area than another. Appearance alone does not show how wide or deep the separation is.
What it may—and may not—mean
In diastasis recti, the two rectus muscle columns are farther apart and the connective tissue between them is stretched. The Tupler Technique® focuses on the condition of that midline as well as its width. That is why a useful check looks above, at, and below the navel.

A useful next step
Notice which movement brings out the bulge, then avoid repeating it for a visual test. A Diastasis Coach or qualified clinician can assess the midline. Get medical advice for pain, a firm lump, skin-color change, nausea, or vomiting.
Common questions
Can a ridge or bulge diagnose diastasis recti?
No. It is a useful sign to notice, but a hands-on assessment of the whole midline is needed.
What should I do when the sign appears?
Stop the movement that brings it out, note when it happens, and arrange an appropriate assessment instead of repeatedly testing it.
When should I get urgent medical help?
Seek urgent care for severe or rapidly worsening pain, vomiting, fever, skin-color change, fainting, or a hard tender bulge.
