In short
A caesarean is one of the commonest operations in the world. The cut used for it heals well in most women, so a hernia through that scar is uncommon. It does happen.
More often, a bulge after a caesarean turns out to be something else. Working out which one it is comes first.
The usual caesarean cut is low and side to side, just above the pubic bone. It runs across the belly wall, not along it. The layers above help hold it shut. That is why hernias through it are less common than through an up-and-down scar.
A hernia is more likely if the wound got infected, if the cut had to be made longer, if it was an emergency, or if diabetes, smoking or extra weight slowed healing.
Three things that bulge after a caesarean, and how they differ
| What it is | Where you see it | What settles the question |
|---|---|---|
| Hernia through the scar | A soft lump on or just above the scar line, worse on standing or coughing | A gap you can feel, seen on a scan |
| Separated tummy muscles | A ridge down the middle when you sit up, above the navel | The muscles part, but the sheet between them holds |
| Loose skin and fat | A fold that sits over the scar and hides it | No gap on the scan. It does not change when you cough |
| Stitch lump | A firm lump the size of a pea in the scar | Small, fixed, and it does not grow when you strain |
Bring your caesarean discharge summary and any scan reports to the consultation.
In clinic the bulge is felt while you stand, while you lie flat, and while you cough. A hernia has an edge you can feel and it changes with position. Loose skin does not.
An ultrasound is often enough for a small gap. A CT is used when the bulge is large, when there has been a repair before, or when the plan needs to show which layer the gap sits in. There is more on that choice on the imaging page.
This is the question that changes the plan most. A growing baby stretches the repair. So a repair done before another pregnancy fails more often than one done after the family is complete.
If another pregnancy is planned, a small hernia that does not hurt is usually watched. If it hurts, if it is growing, or if bowel has been trapped even for a short time, it is dealt with sooner.
Fixing the hernia during a planned caesarean sounds tidy, and it is sometimes done. The problem is that the tissues are then soft, swollen and stretched. A repair made that way holds less well.
When it is considered, the choice is made with the doctor doing the caesarean, not on its own.
Small gaps in good tissue can be closed with stitches alone. Larger ones, and any hernia that has been repaired once already, hold better with mesh. The route may be open, keyhole or robotic. The size of the gap and the earlier surgery decide which.
If the real problem is loose skin and not a gap, that is a different operation. It should not be sold as a hernia repair.
No. A shelf of skin and fat sitting over the scar line is common and is not a hernia. Separated tummy muscles higher up the midline also bulge. A scan tells them apart.
Most hernias through a scar show within the first two years, and many in the first year. A bulge that appears much later is worth checking but is less often a hernia through that scar.
If another pregnancy is planned, repair usually waits. A growing uterus stretches the repair and makes it more likely to fail. The exception is a hernia causing pain or getting stuck.
It is sometimes done, but the tissues are soft and swollen at that point, so a repair done then fails more often. The decision is made with your obstetrician.
Small defects in good tissue can sometimes be closed with sutures alone. Larger defects, and hernias that have already been repaired once, generally do better with mesh.
