What is an umbilical hernia?

An umbilical hernia during pregnancy is not quite the same as in a standard context. Because pregnant women are more prone to weight gain — for obvious reasons — a hernia requires particular attention in expectant mothers. So let us take a thorough look at the subject so you can be fully informed.

What is an umbilical hernia during pregnancy?

To begin with, it is worth knowing that a hernia is characterised by the protrusion of an organ, or part of an organ, out of its usual location. This most often involves the small intestine in particular, which manages to pass through the abdominal wall via a natural opening. In a so-called "standard" context, an umbilical hernia remains benign. However, in the case of pregnancy, if one develops at this particular time, it becomes somewhat more problematic.

The risks of an umbilical hernia during pregnancy

During pregnancy, the navel is subject to significant and persistent tension. As a result, it can open up in depth, potentially exposing the contents of the abdominal cavity. Indeed, this protrudes through the opening and presents as a swelling of the navel. Furthermore, umbilical hernias have a strong tendency to enlarge — especially as the weeks of amenorrhoea go by. Finally, an umbilical hernia during pregnancy can be complicated by an obstruction. In other words, the intestine can become trapped in the hernia. This last scenario requires emergency surgery to release it. But how do you know if you are affected?

How can you tell if this applies to you?

First of all, you will notice it visually. If you observe a round swelling — in other words a "lump" — at your navel, make sure to stay vigilant and raise it with your doctor. As for other symptoms that might indicate whether you are affected, they can range from a local discomfort to more significant pain. It is also worth noting that an umbilical hernia during pregnancy can just as easily be asymptomatic.

The risks of an umbilical hernia during pregnancy

Know that it is quite possible for it to remain stable and not to progress. In that particular case, it is preferable to wait until after the birth to address it. That said, with the weight gain that comes with months of pregnancy, the constant pressure exerted by your baby means it risks getting worse. In this scenario, a larger portion of the intestine exits the cavity and can become trapped — this is referred to as a strangulated hernia. This means that a section of the intestine is no longer functioning and can become ischaemic. At this stage, the hernia becomes extremely painful. Surgery must take place without delay.

When should you be concerned?

Given everything we have just explained, if you notice a lump at your navel — with or without pain — it is best to seek medical advice as soon as possible. And if you are in pain, there is no time to lose: you must be examined without delay.
