Repair of Diastasis Recti
Overview
| Purpose | To restore the separation between abdominal muscles, improving core support and abdominal contour. |
| Recommended for | Individuals with persistent abdominal muscle separation (diastasis recti) that does not improve with physiotherapy or exercise, often following pregnancy or significant weight changes. |
| Surgery time | Approximately 1.5 to 3 hours, depending on the extent of repair and whether it is combined with other procedures. |
| Hospital stay | Usually a day surgery or may require an overnight stay, depending on the surgical plan. |
| Recovery | Initial recovery typically takes a few weeks, with gradual return to normal activities. Full healing and restoration of core strength may take several months. |
Diastasis recti is a condition in which the left and right midline muscles (rectus abdominis) separate from the midline, resulting in a midline gap and visible bulge in the abdominal wall. It is one of the more common concerns seen among patients in Singapore, particularly following childbirth or significant weight changes. More pronounced muscle separation can persist long after these changes occur, leaving the abdominal wall weakened and affecting posture, core strength and overall abdominal contour.
Diastasis recti repair is a surgical procedure designed to bring the separated abdominal muscles back together, restoring support to the core and improving abdominal shape. The repair may sometimes be performed as a standalone procedure or combined with other abdominal contouring procedures when appropriate.
What is diastasis recti?
The abdominal wall is made up of paired muscles connected by a band of tissue called the linea alba, which runs vertically down the centre of the abdomen.
Diastasis recti occurs when this connective tissue stretches and weakens, causing the two rectus abdominis l muscles to separate. As the gap widens, the abdominal wall may lose its ability to provide firm support for the internal organs. This can lead to a noticeable abdominal bulge, particularly when sitting up, coughing or engaging the core muscles.
Although the condition is not always painful, it can affect core strength, stability and body confidence, particularly when the separation is significant.
Is diastasis recti only experienced by women after pregnancy?
No, it is not! Although diastasis recti is commonly associated with pregnancy, it isn’t exclusive to postpartum women. A few other groups who can develop it include:
- Individuals with high visceral fat (central obesity)
- Excess intra-abdominal fat increases internal pressure
- This pressure pushes outward on the rectus abdominis muscle, similar to how a growing fetus would
- Over time, this can stretch and separate the abdominal wall
- People with weak abdominal musculature
- Poor core strength reduces the ability to counteract intra-abdominal pressure
- Makes the midline connective tissue more vulnerable to stretching
- Those with chronic increases in intra-abdominal pressure, such as:
- Chronic cough (e.g., from respiratory conditions like Chronic Obstructive Pulmonary Disease)
- Chronic constipation or straining during bowel movements
- Frequent heavy lifting (especially with poor technique)
- Repeated strain gradually widens the linea alba (connective tissue between abdominal muscles)
- People who perform improper core exercises
- Repeated sit-ups, crunches, or high-pressure movements without proper engagement or done too early post child-birth
- Can worsen or contribute to separation rather than strengthen the core
- Individuals with connective tissue disorders
- Conditions affecting collagen integrity (e.g., Ehlers-Danlos Syndrome)
- Weakened connective tissue increases susceptibility to stretching and separation
- Frequent weight fluctuations (yo-yo dieting)
- Repeated stretching and shrinking of abdominal tissue
- May reduce elasticity and resilience of the linea al
Diastasis recti is relatively common, affecting up to around 60% of women in the early postpartum period, with prevalence decreasing over time.
What causes diastasis recti in women?
01
Central Obesity/Visceral Fat
Several factors can place sustained pressure on the abdominal wall and contribute to muscle separation, including:
- Pregnancy – during pregnancy, the uterus expands to accommodate the growing baby. This places progressive pressure on the abdominal muscles, stretching the linea alba and causing the muscles to move apart. Hormonal changes also soften connective tissues, making them more prone to stretching.
- Multiple pregnancies – repeated pregnancies can further strain the abdominal wall. Each pregnancy may stretch the connective tissue again, making it more difficult for the muscles to return fully to their original position.
- Significant weight fluctuations – rapid weight gain or loss can stretch the abdominal wall and weaken connective tissue support, contributing to muscle separation.
- Increased abdominal pressure – activities or conditions that repeatedly increase abdominal pressure, such as heavy lifting, chronic coughing or certain intense exercises, can also contribute to diastasis recti.
- Genetics and connective tissue strength – some individuals naturally have weaker connective tissue, which may increase their susceptibility to abdominal muscle separation.
Benefits of diastasis recti repair surgery
While diastasis recti is often associated with abdominal appearance, the condition can also affect physical function. Repairing the muscle separation may provide several benefits, such as:
- Improved core strength – reuniting the abdominal muscles helps restore the structural integrity of the core, which supports everyday movements.
- Better posture and stability – a stronger abdominal wall helps support spinal alignment and overall posture.
- Reduction of abdominal bulging – muscle repair can reduce the persistent abdominal bulge often associated with diastasis recti.
- Greater physical comfort – some women report feeling easily bloated and can visibly see the abdominal bulge increase during and after meals, causing their T-shirts to ride upwards. After repair, they experience improved comfort as the bulge is reduced.
- Able to fit into clothing of choice – many women complain they have to wear loose clothing to hide the bulge. After repair of diastasis and reduction of the abdominal bulge, they feel more freedom in clothing options.
Who may consider diastasis recti repair?
Surgical repair may be considered when the abdominal muscles remain significantly separated despite physiotherapy or core-strengthening exercises.
Individuals who may benefit from evaluation include those who:
- Notice a persistent abdominal bulge after pregnancy
- Experience core weakness or reduced abdominal support
- Have difficulty engaging abdominal muscles during exercise
- Observe worsening abdominal contour despite maintaining a healthy weight
How does diastasis recti repair work?
Diastasis recti surgery focuses on repairing and restoring the abdominal wall integrity and structure by bringing the separated abdominal muscles back together. By reinforcing the midline repair, the procedure helps restore abdominal contour.

What happens during diastasis recti repair surgery?
Before the procedure, our surgeon (link to doctor’s page) carefully identifies the separation between the rectus abdominal muscles along the midline of the abdomen.
The muscles are gently brought back toward their natural position and secured with specialised sutures along the linea alba, the connective tissue that runs vertically down the centre of the abdomen. This repair reinforces the abdominal wall and reduces the gap between the muscles.Once the muscles are rejoined, the abdominal wall regains greater structural support, which can improve core stability and reduce the visible bulge associated with muscle separation.
Is diastasis recti surgery
a standalone procedure?
Diastasis recti repair can sometimes be performed as a standalone procedure when the main concern is muscle separation and the skin remains relatively firm.
However, in many cases, particularly after pregnancy (link to post-pregnancy abdominal repair), many women also have excess loose skin along with change in umbilicus shape and abdominal contour. In such situations, the muscle repair may be performed as part of an abdominoplasty (link to tummy tuck), which addresses both the underlying muscle separation, loose skin and overall abdominal shape.
The most suitable approach depends on the degree of muscle separation, skin elasticity and the patient’s overall treatment goals. A personalised surgical plan ensures that both functional support and natural abdominal contour are carefully considered.
What happens during diastasis recti repair surgery?
Many patients living with diastasis recti notice that the abdominal bulge or weakness persists despite exercise or weight management. Understanding what the treatment process involves can help patients feel more prepared and confident when considering repair.
Most procedures follow three key stages: assessment before surgery, the surgical repair itself and the recovery period as the abdominal wall heals.
Before surgery
During your consultation, Dr Pearlie (link to dr bio) will assess the degree of muscle separation and evaluate your skin elasticity and overall abdominal contour. She will also review your medical history, lifestyle, and aesthetic goals to determine the most appropriate surgical approach for you.
If diastasis recti is your primary concern, it can often be repaired laparoscopically using minimal incisions. For patients seeking further refinement, additional fat removal procedures, such as high-definition liposuction, can be performed at the same time to enhance abdominal shape and contour, also through small, discreet incisions.
If there is significant excess skin or fat, Dr Pearlie may recommend either a mini-abdominoplasty or a full abdominoplasty (link to tummy tuck) in combination with diastasis repair to achieve optimal results.
In selected cases, she also offers advanced body contouring techniques such as rib remodelling (*link to rib remodelling page), performed through small incisions at the back. This emerging procedure is gaining popularity among patients looking to restore a more defined, pre-pregnancy waistline.
During the procedure
The surgery is typically performed under general anaesthesia. The separated abdominal muscles are brought together and secured to recreate a firm abdominal wall. If other procedures have been discussed to be done at the same time i.e. liposuction (link to page), tummy-tuck (link to page) and/or rib remodelling (link to page), this will also be performed during surgery.
The procedure is typically performed under general anaesthesia. During surgery, the separated abdominal muscles are carefully brought back together and sutured along the midline to restore the abdominal wall.
If additional procedures have been planned, such as liposuction, abdominoplasty (tummy tuck), and/or rib remodelling, these will be performed concurrently during the same operation to achieve a more comprehensive and harmonious result.
After Surgery
Following surgery, patients can expect some swelling and discomfort during the initial healing phase. This is typically well controlled with oral pain medication, which is initiated at the end of the procedure.
Most patients are discharged home within 1–2 days and will be provided with an abdominal binder and corset to support healing and reduce swelling.
In many cases, patients may begin supportive therapies provided by the clinic, such as manual lymphatic drainage (MLD) massage and LED light therapy, within the first week to help optimise recovery.
Over the following weeks, the abdominal wall gradually regains strength as the tissues recover.
Recovery focuses on protecting the repaired abdominal muscles while allowing the body to heal.
Patients are typically advised to:
- Avoid heavy lifting during early recovery
- Wear provided compression garments for at least 8 weeks
- Gradually reintroduce physical activity
- Attend follow-up appointments to monitor healing

Frequently Asked
Questions
Is diastasis recti the same as a hernia?
Diastasis recti occurs when the connective tissue between the rectus abdominis muscles separate from the midline. A hernia, on the other hand, involves internal tissue or organs pushing through a weakened area of the abdominal wall. It is possible to have both diastasis recti and a hernia.
What is the difference between diastasis recti repair and a tummy tuck?
Diastasis recti repair focuses specifically on repairing the separated abdominal muscles to restore core strength and stability. The procedure addresses the underlying muscle separation that occurs when the connective tissue between the abdominal muscles stretches and weakens.
A tummy tuck (abdominoplasty), on the other hand, primarily removes excess abdominal skin and fat while tightening the abdominal contour. During the tummy tuck procedure, if there is diastasis recti present, surgeons will repair this at the same time.
In other words, diastasis recti repair restores the abdominal wall structure, while a tummy tuck focuses on improving the overall abdominal shape and skin contour. The two procedures are often combined to achieve both functional and aesthetic improvement.
A consultation helps determine whether muscle repair alone or a combined procedure would be more suitable based on the degree of muscle separation, skin elasticity and treatment goals.
Can exercise fix diastasis recti?
Appropriately timed, targeted physiotherapy and core exercises may help improve mild cases. However, significant muscle separation may require surgical repair to fully restore the abdominal wall.
How is diastasis recti diagnosed?
Dr Pearlie will examine you physically as well as perform an ultrasound analysis in clinic to check for the presence and degree of separation of abdominal muscles. In some cases, a CT scan may be needed.
How long does recovery take after diastasis recti repair?
Most patients resume light activities within a few weeks, although full recovery and strengthening of the abdominal wall may take several months.
Will the separation return after surgery?
With proper healing and core support, recurrence is uncommon. Maintaining a healthy weight and avoiding excessive abdominal strain during recovery can help support long-term results.
How can I check for diastasis recti at home?
A simple self-check can sometimes help identify possible muscle separation. While lying on your back with your knees bent, gently lift your head and shoulders slightly off the floor while pressing your fingers along the midline of the abdomen.
If you feel a gap or indentation between the abdominal muscles, it may indicate diastasis recti. However, a medical assessment is recommended to confirm the diagnosis and determine the degree of separation.
Can men develop diastasis recti?
Yes, although diastasis recti is commonly associated with pregnancy, men can also develop the condition. Factors such as significant weight gain, heavy lifting, chronic abdominal pressure or connective tissue weakness may contribute to abdominal muscle separation.
Evaluation by a doctor helps determine whether treatment is necessary and what options may be appropriate.
