Diastasis recti: symptoms, self-check and treatment
Diastasis recti is caused by the thinning and widening of the linea alba, the connective tissue that joins the two rectus abdominis muscles, so the muscles drift apart. It is a common condition after pregnancy, and affects men too. It changes the shape of the abdomen and is sometimes accompanied by pain along the midline; it is managed first with rehabilitation, and surgery is an option for selected cases.
Symptoms and self-check: what to look for
What people with diastasis recti notice, what comparative studies actually show, and a simple test to do at home before asking for an ultrasound.
What people notice
- A ridge or “fin” along the midline when sitting up from lying down, coughing or straining;
- A belly that stays rounded after pregnancy, often more so at the end of the day or after meals;
- A pulling or aching feeling along the midline, worse with effort;
- Sometimes a soft swelling at the navel, which may be an umbilical hernia.
What the data show
Low-back pain, urinary incontinence and bloating are often reported by people with diastasis, but in studies comparing people with and without it they were not more frequent. In 300 first-time mothers followed for twelve months after birth, lumbopelvic pain did not differ (Br J Sports Med 2016). In 72 women matched for age and number of births, incontinence and prolapse were not more common, while abdominal pain was (Physiotherapy 2021). In 1,575 men no association with low-back pain was found (Hernia 2024). The association is a clinical finding, not a proven consequence, so these symptoms deserve their own assessment.
The self-check in four steps
- Lie on your back with your knees bent and your feet flat on the floor.
- Place your fingertips across the midline, just above the navel.
- Lift your head and shoulders slightly off the floor, without pulling your chin to your chest.
- Feel whether the fingers sink into a gap, then repeat above and below the navel.
It is a screen, not a measurement: the width and length of the gap, and any hernia, are confirmed with dynamic ultrasound.
When to get checked
- A ridge that persists beyond the first months after birth;
- Pain along the midline with effort that limits daily activities;
- A self-check suggesting a gap, to be measured on ultrasound;
- A swelling at the navel that is firm, tender or does not go back in: seek prompt medical attention.
The symptoms of diastasis recti · The self-check, step by step
What happens from the first consultation to the final check-up?
Every person follows a defined pathway, with clear timing and clear responsibilities. Nothing is left to improvisation: knowing in advance what happens reduces anxiety and improves the outcome.
- First contact — You write through the form or call the office. Emma Gadda takes your request, explains how the assessment works and schedules the appointment. At this stage it helps to have previous tests, operative reports and, where available, imaging studies already at hand.
- Initial consultation — A complete clinical assessment of the abdominal wall: physical examination, medical history, and evaluation of form and function together. The consultation covers the problem as a whole — diastasis, hernia, incisional hernia, the aftermath of previous surgery — and Dr. Fiori explains what is realistic to achieve.
- Tests and assessment — When needed, an ultrasound or CT scan of the abdominal wall and the preoperative workup are ordered. The findings are then reviewed with the patient, and the choice of technique is discussed on the basis of that person's actual anatomy. This is the step where the indication for surgery is confirmed or set aside, and where the patient's questions about the findings are answered before any plan is made.
- Planning the operation — The technique is defined — extraperitoneal endoscopic, TESAR, laparoscopic or open — with indications, limits and alternatives set out in writing. Informed consent, length of hospital stay, pain management and return to activity are explained beforehand, not afterwards.
- Surgery and hospital stay — Surgery takes place in hospital, with a full team. The stay is short and monitored; instructions for the first few weeks are provided at discharge. At discharge you receive written instructions on wound care, medication, warning signs to watch for, and contact numbers for urgent matters.
- Follow-up and recovery — Scheduled follow-up visits over the following weeks, with step-by-step guidance on movement, work and physical activity. Where indicated, physical therapy is added, so that the wall goes back to working — not just to being closed.
- Final follow-up — A final assessment of the morphological and functional result, compared against the starting point. The pathway closes only once form and function have been verified — and a channel stays open for any questions that come later.

Frequently asked questions
- What is diastasis recti in simple terms?
- It is caused by a widening of the linea alba, the tissue between the two “six-pack” muscles, so they separate. The wall loses part of its ability to contain and stabilize the trunk.
- How do you know if you have a diastasis?
- Lie on your back, lift your head and press your fingers just above the navel. If they sink into a gap wider than about two centimeters, a diastasis is likely and should be confirmed by ultrasound.
- Is diastasis recti only a cosmetic problem?
- Not always. Low-back pain, incontinence and bloating are often reported alongside it, but in studies comparing people with and without diastasis they were not more frequent; the symptom that was more common is abdominal pain along the midline (Physiotherapy 2021). The change in shape and a feeling of a less stable core are the symptoms the European Hernia Society guidelines consider most relevant (Br J Surg 2021).
- Can exercises close a diastasis?
- Guided rehabilitation, such as transversus and breathing-led deep-core work, is the first step and improves trunk control for many people, even when the gap itself does not narrow. There is no evidence that crunches widen a diastasis; exercises that make the midline dome are usually postponed and reintroduced gradually. Surgery is an option for selected cases, when symptoms or the change in shape persist after rehabilitation.
- Does diastasis recti affect men?
- Yes. In men it is usually linked to central obesity or repeated heavy straining. In a study of 1,575 men, diastasis was associated with hernia, not with low-back pain (Hernia 2024).
- Who is behind this site?
- Content is written and reviewed by Dr. Federico Fiori, abdominal wall surgeon at ASST Santi Paolo e Carlo in Milan, who described the TESAR technique. Emma Gadda coordinates the patient pathway and is the person you speak to when you get in touch.
- Can diastasis recti heal on its own?
- A mild diastasis that appears during pregnancy often improves on its own in the first few months after birth. Beyond that window spontaneous improvement is less likely: rehabilitation is the first step, and a wide or long-standing gap is assessed by a specialist.
- Is diastasis recti dangerous?
- Diastasis recti itself is not life-threatening. It can be accompanied by pain along the midline and a feeling of a less stable core, and it sometimes occurs together with a hernia that does need treatment. A clinical assessment tells the two apart.
- What is the difference between diastasis recti and a hernia?
- In a diastasis the linea alba thins and the two rectus muscles drift apart with no true hole in the wall. In a hernia there is a real defect through which tissue can protrude. The two can coexist, so an examination and, when needed, an ultrasound are used to distinguish them.
- How long does recovery from diastasis recti surgery take?
- In the published series the median hospital stay was 3 days (range 2 to 10) across 120 consecutive operations (Hernia 2026). Most people return to desk work in about two to three weeks; return to sport and heavy lifting is agreed case by case.

- When does diastasis recti need surgery?
- Surgery is considered when the gap is wide or long-standing, when symptoms persist despite rehabilitation, or when a hernia is also present. The decision is made after a clinical assessment, not from the finger-gap test alone.
- Can you have diastasis recti without being pregnant?
- Yes. It also affects men and women who have never been pregnant, most often linked to rapid weight change, central obesity or repeated heavy straining.
