Summary:
Around 60% of women show some degree of abdominal muscle separation in the weeks following delivery. For many, the gap narrows naturally in the months after that. For others, it doesn't.
If you're months or years postpartum and still struggling with a persistent abdominal bulge, lower back pain, or a visible ridge when you sit up, diastasis recti may be the reason.
Why does this happen? And how can a tummy tuck surgery help? Read on to find out.
Diastasis recti is the separation of the two vertical abdominal muscles along the midline of the body. It's not a tear or a hernia. The muscles themselves remain intact, but the connective tissue holding them together stretches and weakens, allowing a gap to form.
The rectus abdominis muscles (the paired vertical muscles running down the front of the abdomen) are held together at the centre by a band of connective tissue called the linea alba. During pregnancy, as the uterus expands, the growing pressure stretches this tissue and separates the two muscle bellies.
Diastasis recti is strongly associated with pregnancy, but it also occurs in men and in women who've never been pregnant. In these groups, increased abdominal pressure due to obesity, significant weight fluctuations, and heavy loading are considered contributing factors.
Primary diastasis recti refers to a separation present from birth, commonly seen in premature infants whose connective tissue hasn't fully developed. Secondary diastasis recti develops as a result of the forces described above and is what most adults seeking treatment are dealing with.
Not every symptom of diastasis recti is visible, and not every visible change is what it appears to be. Here's what the condition can actually look and feel like, and when it's worth seeking medical attention.
A recognisable sign is a visible doming or ridging along the midline of the abdomen when you sit up or perform a crunch. This happens because the weakened linea alba allows the abdominal contents to push outward when pressure builds inside the abdomen. If you're noticing this, it's worth getting it assessed by a surgeon or physiotherapist rather than assuming the cause.
Many patients with diastasis recti report persistent lower back pain and a sense of instability during exercise. Back pain can have several contributing causes, so an assessment is the right way to identify what's driving it. Difficulty with tasks that require bracing, such as lifting, is also commonly reported.
The pelvic floor and the deep abdominal muscles work closely together. When that relationship is disrupted, you may notice symptoms such as urinary leakage, pelvic heaviness, or persistent bloating that doesn't seem related to what you've eaten.
These symptoms overlap with several other conditions, including hernia, pelvic organ prolapse, and lumbar spine issues. You won't be able to confirm the cause from appearance alone. A proper examination can help determine what you're actually dealing with.
It's usually the first question people ask, and the answer is: sometimes. It depends on the severity of the separation, how long it's been present, and what kind of programme you follow.
For mild to moderate diastasis recti, physiotherapy is the first approach. Targeted rehabilitation focusing on deep core activation (particularly the transverse abdominis, the deepest layer of abdominal muscle) can improve stability and reduce the visible separation for many patients. Many see meaningful improvement over three to six months of consistent, guided work.
Certain exercises increase pressure inside the abdomen in ways that place excessive load on the linea alba. Traditional crunches, sit-ups, double-leg raises, and heavy lifting with poor bracing technique are commonly cited as movements to avoid in the early stages of recovery. They won't necessarily cause permanent damage, but they may slow progress or worsen symptoms.
If you've completed a structured physiotherapy programme over several months and you're still experiencing functional symptoms, visible doming, or significant cosmetic concern, surgery may be an appropriate next step. Physiotherapy can't tighten or reattach connective tissue that's become permanently lax.

When physiotherapy hasn't been enough, surgery offers something it can't: a direct, structural repair. Here’s what a tummy tuck surgery involves and what it can realistically achieve.
An abdominoplasty (tummy tuck) addresses diastasis recti through a technique called plication (the surgical suturing of the separated muscle edges back together along the midline). At Polaris, this repair is performed as part of the standard abdominoplasty procedure, directly correcting the separation rather than working around it. The plication restores tension to the abdominal wall, improving both the structural integrity of the midline and, in many patients, functional core strength.
Alongside the muscle repair, abdominoplasty removes excess skin and fat from the lower abdomen and repositions the navel. At Polaris, the procedure is typically combined with liposuction contouring for a more refined result in terms of waist definition.
For patients who've been through significant weight changes or multiple pregnancies, this also addresses the loose, overstretched skin that exercise alone can't correct.

Your surgeon at Polaris will assess which option suits your anatomy.
If you're planning to have more children, it's worth waiting until after your last pregnancy before having a tummy tuck surgery. Carrying another baby can re-separate the muscles that were repaired.
Surgeons generally recommend waiting at least 12 months after your final delivery to allow all bodily changes to stabilise, including abdominal shrinkage and the end of breastfeeding.
If you're considering combining procedures, the Mummy Makeover programme at Polaris brings tummy tuck surgery together with treatments such as breast procedures to address post-pregnancy changes in one surgical episode.
Recovery varies depending on the extent of your procedure. Your surgeon at Polaris will give you a personalised plan at your consultation, but the table below gives a general indication of what to expect.

Results are generally long-lasting when body weight remains stable. Maintaining a consistent weight and continuing with appropriate core exercise are the main factors that help preserve outcomes over time.
An abdominoplasty with plication directly repairs the separated muscles and is considered more effective than physiotherapy alone for significant diastasis recti.
Not if it's performed purely for cosmetic reasons. MediSave and insurance don't cover cosmetic procedures in Singapore. However, if your surgeon documents a functional indication, such as significant abdominal wall weakness, partial coverage may be possible depending on your insurer and the specifics of your condition.
Surgery is worth considering if conservative treatment hasn't worked. If you're still experiencing functional symptoms such as back pain, core weakness, or pelvic floor issues after completing a structured physiotherapy programme, that's a strong indicator. The same applies if your separation hasn't improved after 12 or more months of conservative treatment, or if you have significant excess skin that can't be addressed non-surgically.
If you're living with the discomfort or cosmetic concern of diastasis recti and conservative treatment hasn't provided sufficient improvement, a consultation with a plastic surgeon can help you understand your options clearly.
