Why Do People Have ‘Outie’ Belly Buttons?

The idea and appearance of any belly buttons can be strange. Part of the reason for this is because of the belly button's isolated location. It isn't in a place that we can easily look at, and so when we start to examine our own, it might look a little weird. Another thing is that it isn't smooth like the rest of our bodies.

And then there's the question 'are you an innie or an outie?' that kids might ask in grade school.

An estimated 90% of all people have innies, which means that 10% are left with outies. Some sources say the number of people with outies is even lower. But how do people get them?

Shortly after we are born, our umbilical cord, which was used to transport nutrients from the mother to the baby during pregnancy, is cut. Many people believe that an outie can be formed when a doctor cuts the umbilical cord a certain way or at a certain distance, but there is no evidence that proves this to be true. An outie bellybutton forms from extra scar tissue or an umbilical hernia, when stomach muscles do not fuse back together properly.

In general, there are no health differences caused by an innie or outie bellybutton. If you feel pain in that area, however, there is a small possibility of incarceration, when abdominal matter gets stuck in the hernia, so make sure to get it checked by your doctor.
