What causes an innie or outie?

Answered by Ricardo McCardle

The formation of an innie or outie belly button is determined by various factors, including the way your body heals and the structure of your abdominal muscles. While the exact cause of innies and outies is not fully understood, there are a few theories that help explain why some people have one type of belly button over the other.

One theory suggests that the way the umbilical cord is cut and clamped shortly after birth can influence the shape of your belly button. If the cord is cut closer to the body, it may result in an innie, while a longer cord may lead to an outie. However, this theory does not fully explain why some people with short cords have outies or vice versa.

Another factor that may contribute to the formation of an innie or outie is the amount of fat and tissue surrounding the belly button. People with less fat and tissue are more likely to have innies, as the skin is drawn inward towards the abdominal cavity. On the other hand, individuals with more fat and tissue are more prone to developing outies, as the skin protrudes outward.

The structure of the abdominal muscles also plays a role in determining the shape of your belly button. If the muscles are tightly connected in the center, it can create a depression, resulting in an innie. Conversely, if the muscles are not as tightly connected, it can cause the skin to be pushed outwards, forming an outie.

Genetics may also be a contributing factor. It is believed that the shape of your belly button can be inherited from your parents. If one or both of your parents have a particular type of belly button, there is a higher chance that you may have a similar shape.

It is important to note that having an innie or outie belly button is simply a variation in appearance and does not have any significant health implications. While some people may have personal preferences or aesthetic preferences for one type over the other, both innies and outies are considered normal and natural.

In my personal experience, I have an innie belly button. Growing up, I remember comparing my belly button with my friends and noticing the different shapes. It was interesting to learn that the formation of innies and outies can vary and is influenced by multiple factors. It’s fascinating how something as small as a belly button can have such diversity among individuals.
