Abdominal diastasis is the separation of the rectus abdominis muscles along the midline, normally held together by the linea alba. It's a common condition after pregnancy, significant weight fluctuations, or intense physical strain, and can cause both a change in abdominal contour and functional symptoms such as lower back pain and a feeling of core weakness.

Didactic illustrationOn the left, diastasis: the rectus abdominis muscles pulled apart and the linea alba — the band of tissue that joins them in the centre — widened. On the right, the normal abdominal wall, with the recti side by side at the midline. Surgical repair brings the muscles back together and reinforces the linea alba.

Surgical treatment is individualized: the most appropriate technique depends on the degree of diastasis, the presence of associated hernias, excess skin, and each patient's goals. Explore the approaches used by Dr. Solon Gonçalves below.

Quick answer
  • Diastasis is not a hernia. The linea alba is widened but continuous — there is no opening in the wall.
  • From 2 cm wide, according to the European Hernia Society. It is common: between 30% and 68% of women still have it after giving birth.
  • Not every diastasis needs surgery. Physical therapy may be tried first, and many cases never reach the operating room.
  • Surgery comes in when there are symptoms — pain, core instability, an associated hernia — and conservative treatment has not worked.
  • Four techniques: SCOLA, MILA, MAMI and abdominoplasty. What decides between them is how much excess skin there is, the degree of laxity and the body fat percentage.
  • One day in hospital. Back to work at around 15 days with SCOLA and MILA, and 30 days with MAMI and abdominoplasty.
  • Not covered by a health plan: diastasis repair is always private.
BEFORE SURGERY

Not every diastasis needs surgery.

The European Hernia Society technically defines diastasis as a linea alba wider than 2 cm. And it is extremely common: practically every woman has some degree of it at the end of pregnancy, and between 30% and 68% still have it after giving birth. Having diastasis is not, in itself, having a disease — much of it resolves on its own or stays entirely free of symptoms.

That is why the European Hernia Society guidelines recommend that physical therapy be tried before surgery is considered. A meta-analysis pooling 34 randomized trials and more than 1,500 postpartum women showed that abdominal exercise can reduce diastasis, isotonic exercise in particular — an effect not repeated with isometric exercise alone.

Surgery comes in when the diastasis is genuinely symptomatic — pain, a feeling of instability in the core, an associated hernia — and has not responded to an adequate period of conservative treatment. On what the science does and does not show about diastasis, lower back pain and function, I wrote a detailed piece with the sources.

CLASSIFICATION

How wide the diastasis is — and what that measure tells you.

In 2021 the European Hernia Society proposed a classification that describes diastasis along three criteria at once: the type, the distance between the rectus muscles, and whether there is an associated hernia. The measurement is taken with ultrasound or calipers, 3 cm above the umbilicus.

CriterionCategories
T — TypeT1 = after pregnancy · T2 = with adiposity
D — Inter-rectus distanceD1 = >2 to 3 cm · D2 = >3 to 5 cm · D3 = >5 cm
H — Concomitant umbilical and/or epigastric herniaH0 = without · H1 = present

Two important caveats. First: a separation of up to 2 cm is considered physiological — which is why the D1 band starts above 2 cm and not at zero. Second: the classification describes the case, it does not prescribe the treatment. The European guideline does not tie surgical technique to centimetre bands — the criterion it links to management is whether or not there is an associated hernia. And between SCOLA, MILA, MAMI and abdominoplasty, what decides is how much skin is left over, the degree of laxity and the body fat percentage.

It is worth distinguishing this from another classification that circulates often: the one from the German Hernia Society and the International Endohernia Society, which uses the letter W and different bands — W1 below 3 cm, W2 from 3 to 5 cm and W3 above 5 cm. The two are not interchangeable: W1 takes in measurements that the definition of diastasis considers normal, whereas D1 starts above 2 cm.

COMPARISON

HOW IT WORKS

The process, from evaluation to returning to your routine.

01

Evaluation

Physical exam, history, and discussion of your goals to determine whether surgery is indicated and which technique fits your case.

02

Imaging

Ultrasound or CT imaging to measure the diastasis and identify any associated hernias.

03

Surgery

Performed in a hospital setting, using the technique defined during evaluation — laparoscopic, robotic, or traditional abdominoplasty.

04

Recovery

Initial hospital monitoring, pain control, and specific guidance for the first few days.

05

Follow-up

Gradual return to activities, with follow-up visits to track your recovery.

FREQUENTLY ASKED QUESTIONS

Common questions about diastasis surgery.

Is diastasis the same thing as a hernia?+

No. In diastasis the linea alba is widened but continuous: the rectus muscles move apart and the wall becomes thinner, without an actual opening. In a hernia there is a genuine weak point, with a rupture of the musculature and the aponeurosis, which opens a passage through which intra-abdominal contents move from one place to another. The two often coexist, because the same weakening of the midline favors both — and when that happens the repair is usually done in the same operation. The distinction matters because it changes the technique indicated and also what a health plan covers.

How long does the surgery take?+

It varies by technique and the extent of the repair — from about 1 hour in simpler cases to 3 hours or more when extensive abdominal wall reconstruction or skin removal is involved. The exact time is only determined after an individual evaluation.

What type of anesthesia is used?+

It depends on the technique: laparoscopic or robotic procedures are usually done under general anesthesia or spinal anesthesia with sedation; traditional abdominoplasty is generally done under general anesthesia. The pre-anesthesia evaluation determines what's appropriate for each patient.

Will I need to stay in the hospital?+

The plan is one day in hospital for every technique: the patient has the operation, stays overnight and is discharged the following day. This may vary according to the extent of surgery and each patient's recovery.

Will I feel pain afterward?+

Some degree of discomfort is expected and is managed with hospital analgesia and, later, oral medication. Intensity varies by person and tends to be lower with minimally invasive techniques than with traditional abdominoplasty.

Will I need drains?+

With some techniques, yes, temporarily — particularly when skin removal is involved, as in abdominoplasty. Drains are used less often with laparoscopic or robotic techniques. The need is assessed on a case-by-case basis.

Will the scars be visible?+

It depends on the technique: SCOLA and MILA/MAMI use small incisions (MAMI can take advantage of an existing C-section scar, when appropriate), while traditional abdominoplasty leaves a larger suprapubic scar. This is discussed in detail during your evaluation, considering the degree of diastasis and any excess skin.

Will I need to wear a compression garment?+

Yes, wearing a compression garment or binder after surgery is common across nearly all techniques, to support the abdominal wall during healing. The duration is determined individually.

How long will I be off work?+

Return to work generally happens at around 15 days with SCOLA and MILA, and at around 30 days with MAMI and abdominoplasty. The timeframe also depends on the type of work involved and on each patient's recovery.

When can I return to physical activity?+

High-impact exercise or activities that involve lifting weight are generally cleared at around 30 days with SCOLA and MILA, and between 45 and 60 days with MAMI and abdominoplasty. Clearance is always progressive, according to healing and medical follow-up.

What are the possible risks and complications?+

As with any abdominal wall surgery, there are risks described in the medical literature, including bleeding, infection, seroma (fluid buildup), altered sensation in the operated area, and, less commonly, recurrence of the diastasis. Rates vary by technique and individual patient factors, and should be discussed individually before deciding on surgery.

Are there contraindications for surgery?+

Yes. Clinical conditions that don't allow for safe anesthesia, uncontrolled obesity (which may be a temporary contraindication until weight is addressed), and plans for a near-future pregnancy are factors typically considered — each case is evaluated individually.

Can the diastasis come back after surgery?+

Recurrence is possible, as with any abdominal wall reconstruction, particularly with a new pregnancy, significant weight fluctuation, or inappropriate physical strain during recovery. Results vary by individual factors, which is discussed during your evaluation.

Is diastasis surgery covered by a health plan?+

There is a health-plan code for diastasis, but only for the open route. I do not perform diastasis surgery through a health plan in any technique — neither minimally invasive (laparoscopic or robotic) nor abdominoplasty: it is always private. What is possible is, when there is a real medical indication that is functional rather than aesthetic, or when there is an associated hernia, to ask the plan to cover part of the hospital stay and of the surgical materials; the surgical team's fees always remain private. Everything is agreed and put in writing before surgery. For other operations, what the plan covers can only be said after a medical assessment of the case.

Do you operate through the SUS, the Brazilian public health system?+

This channel is for my private practice. Through the SUS, care does not go through my private practice: the only way to be operated on through the SUS is to go to the health post or Basic Health Unit nearest your home, be assessed by a doctor and, if indicated, be placed in your municipality's regulation queue. The surgeon does not choose the order of who gets operated on through the SUS — the queue is followed strictly, according to SUS rules. I am a Professor of Surgery at the School of Medicine of the Federal University of Uberlândia and I operate on SUS patients at the university hospital, HC-UFU, but it is not possible to schedule your care directly with me through these websites or contacts.
