What Is Diastasis Recti After Pregnancy, and Can a Tummy Tuck Fix It?
By Dr. Sushrut Tated, plastic surgeon
Diastasis recti after pregnancy is a widening of the gap between the two vertical tummy muscles, causing a bulge or doming of the abdomen. It is very common and often improves in the first year, helped by guided core and pelvic floor exercise. A persistent wide gap with loose skin can be repaired during a tummy tuck.
Dr. Sushrut explains tummy tuck
What is diastasis recti?
The rectus abdominis muscles run down the front of the abdomen on either side of a band of connective tissue called the linea alba. During pregnancy the growing womb stretches this band, and the muscles move apart. After birth the gap often remains wider than before. This is diastasis recti, also called abdominal separation.
It is very common. In one study that followed women from pregnancy, about 60% had a measurable gap six weeks after birth, and about a third still had one at 12 months.
How can you check for it?
- Lie on your back with knees bent and feet flat.
- Place your fingertips across the midline just above the belly button.
- Gently lift your head and shoulders.
- Feel for a gap between the muscle edges and note how many fingers fit, and whether the area domes or sinks.
A physiotherapist or doctor can measure it more accurately, sometimes with ultrasound.
What symptoms can it cause?
- A bulge or “pooch” that stays despite weight loss.
- Doming down the middle of the abdomen when sitting up.
- Back or pelvic discomfort and a feeling of weak core support.
- Sometimes a small hernia at the belly button.
What are the treatment options?
| Option | Suits | Points to consider |
|---|---|---|
| Time | The first months after birth | The gap often narrows on its own |
| Physiotherapy | Most women, especially in the first year | Focuses on deep core and pelvic floor; evidence is still developing |
| Weight management | Excess abdominal fat | Fat inside the abdomen pushes the wall forward |
| Tummy tuck with muscle repair | Persistent wide gap with loose skin | Surgery; recovery of several weeks |
| Hernia repair | A hernia at the belly button or midline | Can be combined with a tummy tuck |
When is surgery considered?
Surgery is usually considered when, after at least a year and a trial of physiotherapy, you still have a wide gap with a bulge, loose skin or stretch marks, and your weight is stable. In a full tummy tuck, the muscle covering is stitched together down the middle, excess skin is removed and the belly button is repositioned. When breast changes are also a concern, the operations may be combined as a mommy makeover.
What is recovery like after muscle repair?
Repairing the muscles during a tummy tuck adds to recovery, because the stitched muscle needs time to heal:
| Time | What to expect |
|---|---|
| First week | Walking slightly bent forward; binder on; short walks |
| Weeks 2-3 | Many return to desk work |
| Weeks 4-6 | No lifting of young children or heavy shopping |
| Weeks 6-8 | Gradual return to exercise, starting with gentle core work |
Planning help with childcare is important. The full timeline is in tummy tuck recovery.
Myths about diastasis recti
- “Crunches will close the gap.” Some exercises strain the area; guided core work is more appropriate.
- “It is a hernia.” It is a separation, not a hole, though a hernia can occur alongside.
- “Only surgery helps.” Many women improve with time and physiotherapy.
- “Liposuction can fix a tummy bulge after pregnancy.” Liposuction removes fat but does not tighten muscle or skin.
When should you see a doctor urgently?
A painful lump at the belly button that will not go back in, especially with vomiting, needs urgent medical care, as it may be a trapped hernia.
What should you ask at consultation?
- How wide is my gap, and is there a hernia?
- Would physiotherapy help, and for how long should I try it?
- Would a mini or full tummy tuck suit me?
- What does recovery involve with young children at home?

Frequently asked questions
Can a tummy tuck fix diastasis recti?
Yes. During a full tummy tuck the stretched muscle covering is stitched together down the midline (plication), narrowing the gap and flattening the abdomen. Loose skin is removed at the same time.
Can diastasis recti heal without surgery?
Often, partly or fully. The gap usually narrows over the months after birth, and physiotherapy focused on the deep core and pelvic floor can help. Surgery is considered when a significant gap and symptoms persist.
How long after pregnancy should I wait before surgery?
Most surgeons advise waiting at least a year after the last birth, until breastfeeding has stopped and your weight is stable, and ideally until you have finished having children.
Should I avoid crunches with diastasis recti?
Exercises that cause the abdomen to dome or bulge may strain the area early on. A physiotherapist can guide which exercises suit you and how to progress safely.
Is diastasis recti the same as a hernia?
No. In diastasis the muscles are separated but the tissue between them is intact. A hernia is a hole through which contents can push. The two can occur together, particularly at the belly button.
