Diastasis recti repair is an operation that brings the two vertical abdominal muscles, the rectus abdominis, back together when they have separated. The separation, known as rectus diastasis or diastasis recti, is common after pregnancy, as the growing uterus stretches the tissue that joins the muscles in the midline. In many women it improves over the months after birth, but in some it remains, leaving a bulge in the abdomen, a sense of weakness in the core and a “pregnant” appearance that persists despite exercise and weight loss.
The repair is performed by folding and stitching the stretched midline tissue so that the muscles are brought back to their natural position. It can be done on its own or, more commonly, as part of a tummy tuck or mommy makeover when there is also loose skin.
What causes diastasis recti
The two rectus muscles are joined in the middle by a band of connective tissue called the linea alba. During pregnancy, this band stretches to make room for the baby. After birth, it gradually tightens again, but in some women it remains wide and thin. Factors that increase the likelihood include multiple pregnancies, twins, a large baby, a small frame, and repeated heavy lifting soon after birth. Diastasis can also occur in men, most often with significant abdominal weight gain.
Symptoms
- a bulge or ridge along the middle of the abdomen, especially when straining or sitting up
- a rounded abdomen that looks pregnant months or years after birth
- a feeling of weakness or poor support in the core
- lower back discomfort in some people
- a soft, doughy area around the belly button
Diagnosis
A simple self-test gives a first indication. Lie on your back, knees bent and feet flat. Place your fingers across the midline above the belly button and lift your head and shoulders slightly. If your fingers sink between two ridges, with a gap of more than about two finger-widths, diastasis is likely. At consultation the gap is measured at several points and an ultrasound can confirm its width and check for hernias, which often exist alongside diastasis.
When is surgery the right choice?
Physiotherapy should always come first. A structured programme with a physiotherapist experienced in postnatal recovery can reduce the gap and restore strength, and many women need nothing more.
Surgery is worth considering when:
- at least twelve months have passed since the birth
- a supervised exercise programme has been completed without closing the gap
- the gap remains wide, often more than two to three centimetres
- there is a visible bulge, functional weakness or an associated hernia
- you have finished having children
What physiotherapy involves
A good postnatal programme focuses on the deep abdominal muscles, particularly the transversus abdominis, together with the pelvic floor and breathing. Exercises are progressed gradually over months. Movements that strain the midline, such as full sit-ups and heavy lifting with poor technique, are usually avoided in the early stages. Even when surgery is eventually needed, this work improves core function and prepares the body for recovery. Patients who arrive for surgery with good core control generally recover more quickly and are better able to protect the repair afterwards.
Diastasis in men
Diastasis recti is not only a postnatal condition. In men it is most often associated with abdominal weight gain, particularly fat stored deep inside the abdomen, and sometimes with heavy weightlifting. The bulge along the midline is similar. In men, the first step is often weight loss, because deep abdominal fat pushes the muscles apart and cannot be removed with liposuction. Once weight is stable, persistent diastasis can be repaired using the same principles.
Surgical options
| Approach | Incisions | Suitable when | Skin removed |
|---|---|---|---|
| Repair with a full tummy tuck | Low horizontal scar, around the navel | Diastasis plus loose skin above and below the navel | Yes |
| Repair with a mini tummy tuck | Short low scar | Diastasis limited to the lower abdomen, mild skin excess | Some |
| Endoscopic or minimally invasive repair | Small incisions | Diastasis with firm skin and no excess | No |
When loose skin is present, which is common after pregnancy, combining the muscle repair with a tummy tuck gives the best result. When the skin is firm, the muscles can be repaired through smaller incisions, sometimes with endoscopic assistance, avoiding the long scar.
How the repair is performed
Under general anaesthesia, the muscles are exposed along the midline. The stretched linea alba is folded inwards and closed with strong, permanent or long-lasting stitches, usually in two layers, from just below the breastbone down to the pubic bone. This brings the rectus muscles back together and restores the natural tension of the abdominal wall. Any umbilical or midline hernia is repaired at the same time. When the operation is combined with a tummy tuck, excess skin is then removed and the belly button repositioned.
Preparing for surgery
Stop smoking at least four weeks before and after surgery. Stop hormonal contraception if advised. Continue gentle core exercises as guided by your physiotherapist, but avoid heavy straining in the weeks before surgery. Plan for help with lifting children and household tasks for at least six weeks.
Recovery
- Days 1–2: hospital stay; walking starts early, bent slightly forward; the abdomen feels tight
- Days 3–10: rest with short walks; abdominal binder or compression garment worn continuously
- Weeks 2–3: return to desk work for most patients
- Weeks 6–8: heavy lifting and abdominal exercises can gradually resume
- Month 3 onwards: core strength and posture continue to improve
The repaired abdomen feels firm and tight for several weeks. Coughing or laughing can be uncomfortable at first, and holding a pillow against your abdomen helps.
Risks
Possible risks include bleeding, infection, fluid collection under the skin (seroma), a feeling of tightness that makes breathing deeply uncomfortable for a few days, stitches that can be felt, recurrence of the separation, and blood clots. When combined with a tummy tuck, the risks of that operation also apply.
Life after diastasis repair
Most women notice a flatter abdomen and a firmer core within weeks. After about three months, a gradual strengthening programme with a physiotherapist helps to rebuild core function on the new foundation. A stable weight and good posture help to keep the repair secure.
Diastasis repair in Istanbul
International patients should allow eight to ten days in Istanbul, or longer when the repair is combined with a full tummy tuck. Walk regularly, drink plenty of water and wear compression stockings during the flight home.
