Diastasis recti — the separation of the abdominal muscles along the midline — is one of the most common yet under-recognized structural changes of the abdominal wall. The term originates from Greek: diastasis means “separation,” and recti refers to the pair of straight muscles that run vertically down the abdomen. In most cases, the condition develops during pregnancy as the expanding uterus stretches the muscles outward and apart; the separation often persists after delivery and cannot be corrected by any amount of core training or lifestyle change. Once the muscles have pulled apart, surgical repair is the only way to bring them back together. For women who cannot regain a flat, firm abdomen despite consistent effort — and for men or children who develop the condition through other causes — diastasis recti repair surgery restores the structural integrity of the abdominal wall and the flat contour patients want.

Dr. John Anastasatos performs diastasis recti repair surgery at his Beverly Hills practice with published authority on this specific procedure. Dr. Anastasatos is the author of a book chapter on full abdominoplasty in Aesthetic Surgery of the Abdominal Wall — a peer-reviewed contribution to the surgical literature on the muscle repair technique described on this page. Board certified by the American Board of Plastic Surgery, a Fellow of the American College of Surgeons (FACS), and named by The Luxe Insider as one of the Top 10 Plastic Surgeons in the World.

Symptoms of Diastasis Recti

Diastasis recti occurs when the band of abdominal muscles separates along the midline. Pressure or stretching of the muscles — most commonly from pregnancy — causes the left and right sides to pull apart. The result is that the muscles no longer create a smooth, taut lower abdomen. A “pooch” appears under the belly button where the loosened or separated abdominal wall pushes slightly outward. Other symptoms of diastasis recti include:

• Lower Back Pain: Weakened core support shifts load to the lumbar spine.
• Urinary Incontinence: Compromised abdominal support affects pelvic floor function.
• Abdominal Pain or Discomfort: Particularly during physical activity.
• Reduced Core Support: Weakness that affects posture, balance, and functional strength.
• Laxity in Skin and Abdominal Tissue: The visible “pooch” or persistent bulge under the belly button.

No amount of planks or abdominal exercises will flatten a severe case of diastasis recti — the underlying problem is structural, not one of muscle tone. Only surgery can restore the midline by bringing the separated muscles back together.

“Diastasis recti is one of the most common reasons patients come in frustrated that their workouts aren’t working. They’re doing everything right — planks, core exercises, consistent training — and the pooch is still there. I explain that it’s not a fitness issue; the muscles are physically separated. Once we bring them back together with permanent sutures reinforced properly, the abdomen responds the way it’s supposed to respond to all that training they’ve been doing.” — Dr. John Anastasatos

Causes of Diastasis Recti

By far the most common cause of diastasis recti is pregnancy. Most women experience some degree of abdominal wall separation during pregnancy as the uterus expands and stretches the muscles outward. Women carrying twins or multiples, women who have had multiple pregnancies, and women with significant pregnancy weight gain are at higher risk for persistent post-pregnancy separation. Other contributing factors include genetics, fitness level prior to pregnancy, and individual differences in connective tissue strength.

Pregnancy is not the only cause. Men, women, and even children can develop diastasis recti from other causes:

• Genetic Predisposition: Some patients — including children — develop diastasis recti as a result of inherited connective tissue characteristics.
• Significant Weight Gain: Extreme weight gain in men or women can stretch the abdominal wall beyond its capacity to recover.
• Weightlifting Injuries: Improper form or excessive loading can cause abdominal wall separation in athletes.
• Medical Conditions: Certain medical conditions can contribute to abdominal wall weakness or separation.

Tummy Tuck for Diastasis Recti

Abdominoplasty — the tummy tuck — is the most effective procedure for repairing diastasis recti. During surgery, Dr. Anastasatos elevates the upper abdominal skin, identifies the separated muscles, and brings them back together along the midline with permanent sutures reinforced twice. This two-layer permanent-suture repair is the key to long-term durability of the correction. The repair extends from the inferior aspect of the sternum down to the pubic symphysis, recreating a continuous, strong midline.

Dr. Anastasatos offers several variations of abdominoplasty depending on what accompanies the diastasis recti:

• Standard Tummy Tuck: Combines diastasis recti repair with removal of excess skin — the most common approach when pregnancy has left both muscle separation and skin laxity.
• Endoscopic Approach: For patients whose skin has retained good elasticity and the primary issue is muscle separation, an endoscopic procedure can repair the diastasis through small incisions with minimal scarring.
• Lipo Abdominoplasty: Adds liposuction to address stubborn abdominal fat alongside the muscle and skin work.
• Mommy Makeover: Combines diastasis recti repair with breast procedures and other body contouring, particularly suited for mothers addressing multiple post-pregnancy concerns together.

The majority of diastasis recti repair patients are women addressing other pregnancy-related concerns at the same time. Mommy Makeover surgery can flatten the diastasis recti pooch alongside breast lift, breast augmentation, vaginal rejuvenation, and other procedures. Note that if a patient becomes pregnant again after repair, diastasis recti can recur — which is why Dr. Anastasatos typically recommends completing childbearing before surgery.

Real Physical Benefits Beyond Cosmetic Improvement

In addition to the cosmetic improvement, diastasis recti repair surgery offers meaningful physical benefits. The core muscles play a central role in daily function throughout life, and as patients grow older, core integrity becomes increasingly important for back support, posture, and injury prevention. Restoring the abdominal wall — not just flattening the pooch — contributes to long-term functional health, not just appearance.

Who Is a Good Candidate for Diastasis Recti Repair

Diastasis recti repair is ideal for patients who have tried conservative approaches without adequate results. Good candidates typically include:

• Post-Pregnancy Women With Persistent Pooch: Mothers whose abdominal bulge has not improved despite consistent core training.
• Completed Childbearing: Patients who have finished having children, since future pregnancies can re-stretch the repair.
• Stable Weight: Weight that has remained stable, ensuring the surgical result will not be distorted by subsequent changes.
• Physically Active: Patients who are otherwise fit but cannot address the structural separation through exercise alone.
• Back Pain or Core Weakness Sufferers: Patients whose diastasis recti has caused functional symptoms beyond aesthetics.
• Good Overall Health: General medical health that supports surgery and recovery.

What to Expect From Recovery

Diastasis recti repair is typically performed under general anesthesia as an outpatient procedure, with the operation taking two to four hours depending on whether it is combined with other abdominoplasty components. Most patients return home the same day.

A compression garment is worn continuously during the first several weeks and during waking hours for approximately six weeks to support the muscle repair. Most patients move in a slightly flexed “bent-forward” posture during the first week and gradually straighten as the tissues heal. Return to desk-based work is typically within two weeks. Core-intensive exercise is restricted for approximately six to eight weeks to allow the muscle repair to heal fully. Final refinement emerges over three to six months as residual swelling resolves.

Frequently Asked Questions About Diastasis Recti Repair

Can diastasis recti be fixed without surgery?

Mild cases sometimes respond to dedicated physical therapy, but significant diastasis recti — the kind that produces a visible persistent pooch — typically cannot be resolved without surgical repair. The muscles have physically separated and need to be brought back together.

How long after pregnancy should I wait before repair?

Dr. Anastasatos typically recommends waiting at least six to twelve months postpartum to allow the body to fully recover, stabilize weight, and finish breastfeeding. Patients planning additional pregnancies are usually advised to complete their family first.

Will the repair last?

Yes, when performed correctly. Dr. Anastasatos’s use of permanent sutures reinforced twice supports long-term durability. The exception is future pregnancy, which can re-stretch the repair — which is why completing childbearing before surgery is usually recommended.

Will insurance cover diastasis recti repair?

Coverage varies significantly by insurer. When there is documented medical necessity — functional symptoms such as back pain, incontinence, or hernia — partial coverage is sometimes available. Purely cosmetic repair is generally not covered. Dr. Anastasatos’s office can help navigate these considerations.

Can diastasis recti repair be combined with other procedures?

Yes, and it commonly is. The most frequent combinations are with excess skin removal (making it a standard tummy tuck), with liposuction (lipo abdominoplasty), and with breast procedures (Mommy Makeover). Combining procedures into a single operation reduces total recovery time compared to separate surgeries.

Is diastasis recti repair available for men?

Yes. Though less common in men than women, men with diastasis recti from weight gain, lifting injuries, or genetic causes are candidates for surgical repair using the same techniques.
