What it is
The main tummy muscle has two halves joined by tissue down the middle. As the baby grows, that tissue stretches and thins, and it can feel like a gap above or below the belly button. It's normal, and for many women it closes over the weeks after the birth.

The HSE self-check
- Lie on your back with your knees bent.
- Lift your head and shoulders a little.
- Put your fingertips above your belly button and feel for a gap in the middle, then turn your fingers sideways to feel its width.
- Check below the belly button too. More than two fingers' width is a gap worth working on.
After a caesarean, the HSE says to wait at least five weeks before checking, so the scar can heal.
What helps first
- A binder or compression top, which the HSE says can help narrow the gap for up to eight weeks after the birth
- The exercises the HSE describes, including crunches, which it says to leave until 12 weeks after a caesarean
- A physiotherapy referral from your GP if you're worried about the gap after eight weeks
When surgery comes in
If the gap is still there after physio and time, and there's loose skin as well, a full tummy tuck can stitch the muscle edges back together while it removes the skin. A mini tummy tuck usually doesn't repair the muscles above the belly button. Liposuction doesn't repair them at all.
What it can't fix
Surgery doesn't replace the work: core strength after the operation still comes from gradual exercise once your surgeon says so. And a later pregnancy can stretch the repair again.
Questions people ask
Is muscle separation after pregnancy normal?
Yes. The HSE says the gap is normal in pregnancy and can take up to six weeks after the birth to reduce, sometimes longer.
How do I check for diastasis recti?
Lie on your back, knees bent, lift your head and shoulders and feel above and below the belly button. More than two fingers is a gap.
Can physio fix it?
For many women physio and time close it enough. Ask your GP for a referral if you're worried after eight weeks.
Does a tummy tuck fix muscle separation?
A full tummy tuck can stitch the muscles together. It's for when physio hasn't been enough and there's loose skin too.
