What exactly causes an innie or an outie?

Admin

Can we settle this once and for all?

Some say it's because the way the skin heals and some say it's because of a hernia. Even Wikipedia is unsure (citation needed).

Since bellybuttons are so overlooked by the medical world, there really isn't much information on the subject. In fact, as far as the medical world cares, all bellybuttons are good for are hernias and now certain surgeries that can be done through the bellybutton.

Other than hernias, I've noticed outies are formed by working out and the bellybutton being pushed outwards by the abdominal wall, or the same happening due to pregnancy. As for being born with them, I do think scar tissue and how the remains of the cord heal is the one true reason for it.

Until doctors actually bother to study the bellybutton and why they form the shapes that they do, which I seriously doubt they want to do because there's really no money behind it, those are the reasons for outies existing as far as I'm concerned.

Mind if I move that to the Belly Article section? Or are we going to do away with that?

The first post is not really an article though Soda pop :P and the article found by Sir Mike, though interesting it's not written by us.

i have a theory maybe it's much more simple than we think. how many monkeys have innies, i've never seen one. who is the first known human race. africans, who pretty much have either really deep innies or outties. what if innies make up for the in you face sexual organs. which are right their eye level for the monkey, that are now hidden with people. nature must have developed a way to attract two legged creatres that used to allmost be four legged. it's the belly hole. the outtie must be the result of genes.

Well, IÂ´m not sure, what is the reason for that! I only know from doctors and exams, that my navel is a kind of hernia! :( I also asked myself very often, why I have such a conspicuous and for me weird looking outie navel (and as a teenaged boy I often wished I could have a normal innie navel :-[; I often had a naive hope, that my navel would simply stay in after doctors pressed it hardly inside during their exams :o, but it never happened and it always popped out at once! :'(). Maybe there is also a role of genes for it, because my (female) cousin and aunt have some kind of outie navels, too, but there are also innies in my family. :-\ So, I think itÂ´s made by nature and some have a predisposition for getting hernias. But if you look closely on navels, you can see, that every navel looks different, equally if innie, inbetween or outie. ItÂ´s like flowers, every are different...
