Seeing someone else's navel, I wonder if you have such a question. Why are some navel sunken and some protruding? Is it determined by genes or caused by doctors?

And in order to look cleaner, many people always pick their belly buttons.
But when I was a child, I heard from the old man at home that you must never dig your navel, or your stomach will leak. I do have a strange feeling every time I dig my navel. ...

Therefore, although I am afraid of this "small black hole" in my stomach, I am still very curious. What is the navel connected to? Will it really leak after digging?
Today, let's take a look.
How is the navel formed?
The navel has nothing to do with the digestive tract. It turned out to be the umbilical cord connecting the fetus and placenta. When the doctor cuts the umbilical cord, the last part will become the navel.
So the navel is actually a scar. Generally, the diameter is about 1-2cm, and the shapes are varied, some are round and deep, and some are vigorous.
Then why is the shape of navel different? Is it determined by genes, or by doctors' scissors when we were born?
What determines the shape of navel?
We know that navel is the stump left by umbilical cord cutting. Is it related to the doctor's skill?
In fact, obstetricians cut the umbilical cord not by sticking it to the navel, but by sealing it from both ends and then cutting it from the middle.

After several hours, loosen the clamp at one end of the seal. At this time, the umbilical cord stump will gradually contract by itself, then fall off and heal, and finally form the shape of navel.
In other words, the shape of the navel is mainly determined by its own factors.
Does picking navel really leak?
Of course not. Umbilical cord has nothing to do with our digestive tract.
However, although it is not connected with the intestine, it is the thinnest part of the abdominal wall. Incision will not leak, but it may lead to abdominal infection.

In addition, it also has nerve reflex directly related to abdominal cavity, which may also cause gastrointestinal discomfort if stimulated excessively.
Speaking of which, you may think the navel is useless and troublesome, but it is really useful.
What is the use of navel?
As the natural pore of abdominal cavity, navel is a rare surgical approach point.
Previous abdominal operations, such as appendectomy and cholecystectomy, often require a few centimeters of incision in the abdomen, which may leave scars on the smooth abdomen after surgery, which is unacceptable to many girls who love beauty.
But now through the single-hole laparoscopic technique, the operation is completed by entering the abdominal cavity from the navel opening. The scar of the operation is completely hidden in the navel, and there is no visible wound on the body surface. This kind of minimally invasive surgery has been used more and more.
Can you choose the belly button?
The "mud" in the belly button is actually the dirt formed by years of accumulated sweat mixed with peeling dander.
According to the investigation, there are 2368 kinds of bacteria that can be identified in navel. According to different living environment and habits, everyone will carry an average of 67 kinds!

There are so many dirty things in the belly button. These more than 2,000 kinds of bacteria may cause local inflammation if left unchecked, and it will definitely not work if they are not cleaned for a long time.
However, the muscle tissue of umbilical eye is very thin and the capillaries are rich, and the nerve reflex of its viscera still exists.
Often picking belly button or improper operation can easily lead to broken skin, which can cause symptoms such as omphalitis, local purulent secretion, redness and odor; In severe cases, it can also cause gastrointestinal discomfort, and the spread of infection can form abdominal wall infection, abscess, peritonitis and even sepsis.
Therefore, we must clean the navel in the right way.
How to clean the belly button?
A small amount of secretion has a certain protective effect on umbilical eyes, so it is not necessary to clean them. However, if the umbilical mud has an odor, it can be cleaned 2-3 times every 1 month.
It is not recommended to get started directly when cleaning, because nails are easy to cause damage to umbilical skin. You can dip a cotton swab in body milk or olive oil and apply it to your navel. After the dirt softens, gently wipe it with a cotton swab dipped in water and then dry it.
It can also be washed directly with clean water.
But if you can't help digging with your hands, you should not only dig lightly, but also keep your hands clean.
