Abdominal Wall Assessment · Referral · CityLink Mall
A tummy that still bulges after the weight has gone is usually not skin and usually not fat. It is the abdominal muscles held apart at the midline — a structural separation in the fascia that no energy device closes, and saying otherwise would be selling you the wrong treatment.
The two halves of the rectus abdominis are not a single sheet. They are joined at the midline by the linea alba, a fibrous raphe formed where the aponeuroses of the flat abdominal muscles interweave — and it is that seam, not the muscle, that stretches during pregnancy. Diastasis recti is the widening of that seam, leaving the muscle bellies sitting further apart than they should.
Two things drive it. The growing uterus pushes the abdominal wall forward and outward, placing sustained tension across the midline for months rather than hours. At the same time, hormonal changes of pregnancy increase ligamentous and connective tissue laxity throughout the body, which is useful for the pelvis and unhelpful for the linea alba. The seam stretches, thins and widens, and in many women it does not fully return afterwards.
The consequence is mechanical. The abdominal wall works as a corset, and its ability to generate tension depends on the two rectus muscles being anchored to a competent midline. When the midline is lax, intra-abdominal contents push forward through the weakened centre rather than being held back, and the result is a persistent central bulge that is present regardless of body fat. It is often most obvious at the end of the day, on standing, or when sitting up from lying — the classic finding being a visible ridge or dome running vertically up the midline during that movement.
This is why the presentation is so frequently misread. The complaint is a tummy that still protrudes after the weight has come off, and the assumption is stubborn fat or loose skin. Both may also be present. But the bulge itself is coming from a structure well beneath both of them, and any treatment directed at skin or fat will leave it exactly as it was.
Assessment
The abdomen after pregnancy has to be examined in layers, because the complaint is almost always a composite. Working out which layer is producing which part of the appearance is the entire purpose of the assessment, and it is what determines whether the answer lies in this clinic, in a physiotherapy practice, or with a surgeon.
No radiofrequency device closes a diastasis. If a clinic tells you otherwise, they are treating the skin above the problem and charging you for the problem.
The Decision
Diastasis is assessed by hand, not by machine. Lying flat with knees bent, the patient lifts the head and shoulders slightly while the examiner palpates the midline above, at and below the umbilicus. What is being judged is how wide the gap is at each level and — at least as importantly — whether the seam has any tension in it at all, because a narrow but completely slack midline can behave worse than a wider firm one. A gap admitting more than roughly two finger-widths on that manoeuvre is conventionally regarded as abnormal, and the vertical doming seen on sitting up is a useful confirmatory sign.
Where separation is significant, the honest answer is that this is not a cosmetic problem and should not be treated as one. The two interventions with a genuine claim on it are physiotherapy-led rehabilitation of the deep abdominal wall — directed at the transversus abdominis and the coordination of the whole corset rather than at conventional abdominal exercises, some of which make the doming worse — and surgical repair, in which the rectus muscles are plicated back to the midline, usually as part of abdominoplasty. Atelier Aesthetics will say so, and will say so before taking money for anything else.
What remains for non-surgical treatment is real but bounded. Skin quality, mild laxity and striae are legitimate targets and they contribute meaningfully to how the abdomen looks — skin firming and collagen work does what it claims to do at that layer. What it does not do is close a gap in the fascia, and a patient who undertakes a course of it expecting a flat midline will have spent time and money on the wrong problem. Being told which layer your complaint is actually coming from is the most valuable thing a consultation about a postpartum tummy can produce.
