Submitted By Jenny Smith  

Outie is one of the ways your belly button takes shape after birth. A navel that has umbilical tips that forcefully passes the periumbilical skin is also termed as “Outie”. Almost 10% of population faces such problem related to their belly buttons.


Many times outies are misunderstood with umbilical hernias, which are basically just a shape that the belly button turns in and there is no health issues related to it. Outies have nothing to do with how the umbilical cord is clamped or cut during the delivery of baby. Outies are nothing more than an extra lump of flesh that appears above the belly. The remaining are usually formed due to an umbilical hernia, just because the belly muscles don’t mingle together properly after the cord is removed, causing the flesh to peek out and show off. Umbilical hernia usually takes a year to heal and there is no other way to fix your kid’s outie. It just that he will stand out as a different kid.

2. Innie Belly Button


The depressive form of belly button is known as “Innie”. It is the most common form and almost 90% population of this world comprises of this form of belly button. The reason behind having an Innie or outie belly is still a medical mystery and researchers are working really hard to find a conclusion very soon. But there are many interesting facts spread around the internet explaining the cause of such belly buttons.

One of the very famous theory regarding belly buttons explain an Innie as a norm while an outie is developed due to genetic aberration in the body. It is a natural selection process and one cannot be tagged as responsible for such a formation. So whatever style of belly you carry, just walk in style and show off.

1. People Without Belly Button


You must be wondering now how come a baby is born without a belly button. Well it’s true and it’s happening. Belly button may look cute but they don’t have much purpose in our overall body. So surprisingly that’s some good for the people who lack a little belly button. Let’s see how this phenomenon can really happen:

The main problem makers are two different types of hernias or we can say holes that might be present at the wall of abdomen during birth known as omphalocele and gastroschisis.

Many mothers have reported their babies having outie belly button because they were born with

Babies with such a rare condition have an abdominal hole that is on one side of the umbilical cord. At the time of birth, the intestine thrust through this hole causing it to become an outie.

On the other hand babies born with omphalocele are born without the beauty of belly button. In first trimester the umbilical cord is basically attached to the inner side of the baby not outer and in the 11th week the abdominal wall covers the intestines, leaving a tiny hole for the umbilical cord. The abdominal muscles later grow together sealing it entirely and forming belly button. Omphalocele happens when this process doesn’t occur and fails to form a belly button.

Omphalocele can be repaired surgically by using the technique called “painting” where the lining of the belly is dried off and allowing the skin to cover the area forming a shape of belly.

If your baby is born with one of these belly button defects, then in that case excellent treatments are available with that can certainly work on this problem.


  • If we talk about innie vs ouite, 80% of babies are born with innie belly button while the rest either have outie belly button or no belly button. So we simply conclude with one amazing sentence and that is whether you have an outie, Innie or no belly button, you just don’t need to bother about and live your life happily as it should be.
