That Gap Down Your Middle Is Not Forever
Most tummy gaps narrow on their own, and gentle, consistent core work can help the rest.
If you can feel a soft gap running down the middle of your tummy and you are wondering how long does diastasis recti take to heal, you are asking exactly the right question. Diastasis recti, the natural separation of the two halves of your abdominal muscles during pregnancy, affects a large share of mums and almost everyone in the early weeks after birth. The reassuring news is that for most women the gap narrows over the first months postpartum, and there is plenty you can do to gently encourage it along.
Quick answer
Diastasis recti usually improves the most in the first eight weeks after birth, as your body naturally reabsorbs pregnancy hormones and your muscles recover. Many gaps continue to narrow up to around twelve months, and consistent deep-core exercise can support that healing. The separation does not always close completely on its own, but a noticeable, functional improvement is common, and a women's health physiotherapist can guide you if progress stalls.
What diastasis recti actually is, and why it happens
Your two rectus abdominis muscles, the ones that form the so-called six-pack, run vertically down your front and are joined by a strip of connective tissue called the linea alba. During pregnancy your growing uterus stretches this tissue and pushes the muscles apart so your baby has room. This is normal and expected. It is not a tear or an injury, it is a stretch.
After birth, the connective tissue starts to recoil and the muscles gradually move back toward the midline. How far and how fast this happens varies hugely from mum to mum, which is why your friend may have bounced back at six weeks while you are still noticing a gap at six months. Both can be completely normal.
It helps to understand the diastasis recti healing stages so you know what to expect. In the first days after birth almost every woman has some separation. Over the early weeks the gap tends to narrow quickly as swelling settles and hormone levels drop. After that, progress becomes slower and steadier, and this is the phase where your own movement habits and gentle exercise make the biggest difference.
How long does diastasis recti take to heal? A realistic timeline
This is the heart of the matter, so let us be honest and specific about the diastasis recti recovery timeline rather than promising a single magic number. Research that has followed women through the first postpartum year shows the steepest improvement happens early, with continued narrowing for many months afterward.
| Time after birth | What is typically happening |
|---|---|
| Day 1 to week 1 | Almost all mums have a visible or palpable gap. This is expected and not a sign anything is wrong. |
| Week 1 to week 8 | The fastest natural narrowing. Many gaps shrink significantly as swelling settles and connective tissue recoils. |
| 2 to 6 months | Slower, steady improvement. Gentle deep-core work starts to add real value here. |
| 6 to 12 months | Continued gradual progress for many women. A plateau here is a good moment to see a physio. |
| Beyond 12 months | Some separation may remain. Improvement is still possible at any stage, even years later, with the right exercises. |
So if you are lying awake wondering does diastasis recti heal on its own, the honest answer is that for many women the gap improves substantially without any formal treatment, especially in those early weeks. For others, a residual gap lingers, and that is where targeted exercise and professional guidance come in. A gap that has not budged after a year is not a failure on your part, it is simply a sign that your core could use some focused, progressive support. If you are weighing up your options, our guide on whether you can close diastasis recti without surgery and what the evidence says walks through the conservative approach in more detail.

How to check for ab separation after birth at home
You can do a simple self-check to get a rough sense of your gap, which is useful for tracking progress over time. Many mums ask is my ab gap normal at 8 weeks postpartum, and a home check helps you answer that for yourself before deciding whether to seek help.
- Lie on your back with your knees bent and feet flat on the floor.
- Place two or three fingers just above your belly button, pointing down toward your toes.
- Gently lift your head and shoulders a small way off the floor, as if starting a tiny nod.
- Feel for the edges of the muscles on either side of your fingers, and notice how many finger-widths of gap you can feel, and how deep or soft it feels.
A gap of one to two finger-widths that feels firm and shallow is often within the normal range of recovery. A wider or deeper gap, or one where your fingers sink in easily, suggests your connective tissue still has work to do. Just as important as the width is the tension. A gap that springs back with tone is healing well, even if it is still a couple of fingers wide.

Keep in mind that a self-check is a guide, not a diagnosis. If something feels off, if you notice a bulge or doming down your midline when you sit up, or if you have pain, a women's health physiotherapist can assess you properly and tell you exactly what stage you are at.
Can you fix diastasis recti with exercise, and what about the doming?
Yes, the right exercise can genuinely help, and this is the part you have real control over. The goal is not to crunch your way to a flat tummy, which can actually make things worse, but to rebuild the deep core that wraps around your middle like a natural corset. Your transverse abdominis and pelvic floor work together to create tension across the linea alba, which is what helps the gap narrow and, crucially, function better.
Gentle, breath-led work is the foundation. Think slow exhales while drawing your lower belly gently toward your spine, pelvic tilts, and supported movements that keep your midline calm. As you get stronger you can progress carefully. The phrase to remember is no doming, no bulging. If a movement makes your belly cone outward down the centre, it is too much for now and you should swap it for something gentler.
Equally important is what to avoid in the early stages. Traditional crunches, sit-ups, full planks and anything that makes you bear down or hold your breath under strain can place too much pressure on healing tissue. The diastasis recti recovery without surgery approach is essentially patience plus the right progressive loading, in the right order. Many women see meaningful change with a consistent routine of just a few focused minutes most days.
Helpful in early recovery
- Deep-core breathing with a gentle belly draw-in
- Pelvic floor connection alongside core work
- Pelvic tilts and supported, low-pressure movements
- Good posture and learning to log-roll out of bed
Best paused for now
- Crunches and sit-ups that load the midline
- Full front planks before your core is ready
- Heavy lifting while holding your breath
- Any move that makes your belly dome or bulge
Wondering how long to see results diastasis exercises take? Most mums who train consistently notice their tummy feels firmer and flatter within a few weeks, with the measurable gap often improving over a couple of months. Progress is rarely linear, so track how your tummy feels and functions, not just the finger-width number.
When to get professional help, and the bigger picture
Most diastasis recti improves with time and gentle exercise, but some situations deserve a professional eye. Book a women's health physiotherapy assessment if your gap has not improved by around the one-year mark, if you feel a persistent bulge or your tummy domes during everyday tasks, if you have lower back or pelvic pain, or if you simply feel unsure and want a clear plan. A physio can check your whole core system, including your pelvic floor, and tailor exercises to your stage. This is especially worth doing after a c-section or any complicated birth.
It also helps to keep diastasis recti in perspective. A residual gap is incredibly common and does not mean your body is broken. Plenty of the postpartum belly that lingers is also down to your uterus still shrinking, normal softening of the skin and tissue, and bloating, which is why so many mums search why is my stomach still big after giving birth. If you want the full picture on the belly timeline, our article on why you still look pregnant weeks after birth explains what is happening week by week. Healing a gap and reshaping your tummy are related but separate jobs, and both take patience.
Rebuild your core with confidence
A clear, gentle progression means you spend your precious nap-time on the moves that actually help your gap, not the ones that set you back.

Frequently asked questions
Will diastasis recti close on its own after pregnancy?
For many women the gap narrows significantly on its own, especially in the first eight weeks as hormones settle and tissue recoils. Some separation may remain after that, and gentle deep-core exercise helps support further closing. If your gap has not improved by around a year, see a women's health physiotherapist.
How long does diastasis recti take to heal?
The fastest natural improvement is usually in the first eight weeks, with many gaps continuing to narrow up to roughly twelve months. With consistent, safe exercise, mums often feel their tummy firming within a few weeks, while the measurable gap improves over a couple of months. Timelines vary a lot between individuals.
Can you fix diastasis recti years later?
Yes, improvement is possible at any stage, even years after birth. Connective tissue and muscle respond to progressive deep-core training regardless of how long ago you gave birth. You may see slower change than in the early postpartum window, but a stronger, more functional core is realistic with consistency and the right guidance.
Which exercises make diastasis recti worse?
Movements that load or strain the midline before your core is ready can set you back. These include traditional crunches and sit-ups, full front planks, and heavy lifting while holding your breath. The simplest rule is to avoid anything that makes your belly dome or bulge down the centre, and choose gentler, breath-led alternatives instead.
Is my ab gap normal at 8 weeks postpartum?
Having a gap at eight weeks is very common and often still part of normal recovery. A separation of one to two finger-widths that feels firm and shallow is generally reassuring. A wider, deeper or very soft gap suggests more healing is needed, which gentle core work supports. If you are worried, a physiotherapy check gives you clarity.
Do I need surgery to fix diastasis recti?
Most women do not need surgery. Conservative care, meaning time plus progressive deep-core and pelvic floor exercise, is the recommended first approach and helps many mums improve meaningfully. Surgery is generally considered only for larger gaps that cause symptoms and have not responded to consistent rehabilitation guided by a professional.
