Innie and outie describe belly button types. An innie goes inward, while an outie sticks outward. Both are normal, harmless, and caused by natural healing after birth.
I once heard friends joking about having an “innie” or an “outie,” and I realized many people did not actually know the difference. Some thought an outie meant a medical problem, while others believed belly button type depends on how the umbilical cord is cut. Curious about the truth, I started researching anatomy articles and medical explanations.
That helped me understand that both innies and outies are completely normal body variations. Learning the facts also cleared up many myths I had believed for years. If you have ever wondered whether an innie or outie is better, more common, or medically different, this guide will explain everything clearly with examples, science, myths, and real world facts.

What Causes an Innie or Outie
Many people believe doctors create innies or outies by cutting the umbilical cord differently. That is actually a myth.
The real cause is how the belly button heals after birth.
Umbilical Cord Healing
Before birth, a baby receives nutrients through the umbilical cord.
After birth, the cord is cut and the remaining stump dries and falls off.
As the area heals, the skin forms either:
- an inward shape
- or an outward shape
This healing process determines whether someone has an innie or outie.
Why Most People Have Innies
Around 90 percent of people have innies.
There are several reasons for this.
Natural Healing Pattern
Most belly buttons naturally heal inward.
Body Structure
The abdominal wall and skin tissue usually pull inward during healing.
Genetics
Genetics may also influence belly button shape.
Why Some People Have Outies
Outies are less common but still normal.
Extra Scar Tissue
Sometimes extra scar tissue causes the belly button to protrude outward.
Umbilical Hernia
In some cases, babies develop a small umbilical hernia.
This happens when tissue pushes through the abdominal wall.
Most umbilical hernias heal naturally during childhood.
Healing Differences
Every person heals differently, which can affect belly button shape.
