The short explanation
It could be either, or both. Separation of the tummy muscles, called diastasis recti, is common after pregnancy, and the gap often narrows on its own over the first months. When it does not, the tummy can still bulge, especially when you strain or sit up. Weight gained in pregnancy also takes many months to come off, and that is normal. A doctor or physiotherapist can check for muscle separation by feeling along the middle of your tummy while you lift your head slightly.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- A pelvic floor or women's health physiotherapist can suggest exercises that strengthen deep tummy muscles. Some traditional sit-ups and crunches may not be suitable while the gap is large.
- A bulge near the belly button that you can push back in, or that hurts, may be a hernia and should be examined.
- Breastfeeding, sleep, stress and time all affect weight after birth. Comparing yourself with others is rarely helpful.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether your muscles have separated or how wide the gap is. An examination is needed.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Do I have a separation of my tummy muscles, and how wide is it?
- Which exercises are safe for me?
- Could there be a hernia?
- When is it reasonable to expect my body to change?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if you have heavy bleeding, a high fever with shivering, chest pain, sudden breathlessness, or thoughts of harming yourself or your baby.
Get help the same day
- Get seen the same day if a bulge near your belly button becomes hard, very painful or cannot be pushed back.
Book an appointment soon
- Book a check within a few weeks if the bulge or back pain is bothering you.
Raise it at a routine appointment
- Ask about muscle separation and exercise at your postnatal check.
