Seven-year-old Chenchen was sent to the hospital by his parents in the middle of the night because of stomach pain, and after examination, it was found that it was caused by a cold stomach, and Chenchen's parents said that this was the third time this month that he had a cold.
How could it be so frequent? The doctor asked a few questions, only to know that Chen Chen had a problem with picking his belly button, because the navel eye can pick out dirt, and it stinks, and he thinks that the dirty things in the intestines run out.
The doctor told Chenchen that the belly button is the channel that connects the child and the mother during pregnancy, and after birth, it is "independent" and has nothing to do with the intestines. But when the navel is exposed, it is easy to enter the cool breeze, and if you pick it often, the skin is getting thinner and thinner, and it is easier to get cold, so he often has stomachaches.
After treatment, Chen Chen soon went home, and he also assured the doctor that he would no longer pick his belly button.
The navel is located in the middle of the human body, close to the intestine and pancreas, if the protection is not good, it is easy to lead to umbilicus inflammation, gastrointestinal cold and other diseases.
First, the navel eye is the first scar in life, and it is not even intestines
It is well known that the fetus is absorbed and excreted by the umbilical cord in the mother's body. The umbilical cord is more than just an empty belt, it has two umbilical veins, an umbilical artery, and an umbilical ureter. Among them, veins transport oxygen and nutrients from the mother to the fetus, and arteries and umbilical catheters transport the waste products of the baby's metabolism to the mother's body, which the mother helps to excrete.
Therefore, the umbilical cord integrates respiration, digestion and metabolism, and is responsible for the life operation of the entire fetal period. When the baby is born, the doctor will preliminarily determine whether the child's respiratory system is normal by crying, usually the louder the cry, the stronger the child's lung function.
After the baby's respiratory system is activated, the role of the umbilical cord ends here, the doctor cuts the umbilical cord, and waits until the incision heals, forming a scar, which is the belly button.
Many people believe that the navel eye is connected to the intestine, and when the metabolic waste in the intestine cannot be excreted normally, it will emerge from the navel eye, so we can often pick out black and smelly things in the navel eye.
In fact, the human digestive system is closed, the main role of the small intestine is digestion and absorption, the main role of the large intestine is to excrete the waste after absorption, the small intestine receives food from the stomach, through digestion and absorption into the large intestine, the waste in the large intestine is excreted through the anus. It can be seen that the navel has no contact with the entire digestive and metabolic system of the person, and it is not connected to the intestines.
From the perspective of human body structure, the navel eye is not directly connected with any internal organs, and on the surface, it does not play much role in the entire operation of the human body.
In fact, as the first scar in life, the belly button eye is located in the middle of the human body, very close to the liver, kidney, intestine, pancreas, although anatomically not connected to any organ, but will affect the operation of the entire abdominal organs, is a very important part of the human body.
When it is still the umbilical cord, it is mainly connected to the liver of the fetus, and after it becomes the navel, the original umbilical vein is converted into the round ligament of the liver, which will still interact with the liver.
In addition, the relationship between the navel and the abdominal organs is mainly through nerves, qi and blood to influence each other. In ancient medicine on the mainland, the belly button, also known as Shenque, is considered to be the center of the human body, and the navel is cold, inflamed, and infected will affect other internal organs.
Second, why can't you pick your belly button?
Compared to the skin in other parts of the body, the skin inside the navel is softer and has many folds. These skins participate in the blood circulation of the human body, and there are corresponding metabolic wastes excreted, because it itself is outside the human body, so we can see metabolic wastes formed by skin sweat and secretions in the navel.
For hygiene reasons, many people like to clear the contents of the navel, and even often pick the navel, from a health point of view, this is not advisable. The secretion of the navel, like ear poop, has a certain protective effect on the navel, and it is easy to cause microorganisms or cool breeze to enter the body after picking it out, causing pain in the stomach and intestines.
Rubbing the skin inside the navel often can easily cause skin damage and inflammation.
The navel is a hollow, usually does not come into direct contact with the outside world, and the chance of injury is relatively small, which is one of the reasons for its delicate skin. If you often pick your belly button, your already thin skin is more likely to hurt, and "Reference News" once quoted the US "Popular Science" website as reporting that scientists found about 1,400 different strains in the navel swab samples donated by 900 volunteers.
These bacteria grow inside the navel and could have been blocked by secretions from the body, and if the skin of the navel is broken, the bacteria can easily enter the body through the wound, leading to conditions such as omphalitis Most of the many omphitis conditions in the clinic are caused by improper cleaning of the navel.
The navel has a warming effect on the human body, and often picking it can easily cause diarrhea, abdominal pain, nausea and vomiting and other diseases.
The human body is a scientific machine, the heart beats to produce heat, through the blood to transmit heat to all parts of the body, excessive heat will be dissipated through the skin, the temperature is not enough, the skin is insulated. Therefore, the protective effect of the skin on the human body is not only reflected in the protection from injury, but also an important factor in maintaining a constant body temperature.
The navel connects the inside and outside of the body, if you pick it often, the internal skin becomes thinner, and the external cold will directly affect the peristalsis of the intestines, causing spasms, resulting in abdominal pain, diarrhea and other symptoms, and seriously affect the entire digestive system.
On the surface, the navel is just a scar and has little effect on the human body. But if the protection is not good, it will still have an impact on health, so it is necessary to correct the bad habit of picking the navel.
Third, the navel eye has various shapes, what does it mean?
The navel eye is common to everyone, and most of them are depressions below the surface of the skin, round or oval in shape, but like fingerprints, everyone is not exactly the same. At present, it is not scientifically possible to explain what determines the shape of the navel, but medically, through clinical observation and records, there are preliminary conclusions about the relationship between the nature of the navel and the disease.
The appearance characteristics of normal navels can be roughly divided into vertical type, T type, round, horizontal horizontal type, irregular type, etc., the common characteristics of these navels are: the navel is concave, the umbilical fossa and the umbilical floor are visible, and there is an umbilical eaves. Regardless of the shape of the interior, as long as it meets these characteristics, it is generally considered a healthy navel.
The criteria for concave navel vary depending on the person's fat and thin, but it is generally necessary to see the low end of the umbilicus.
A bulging belly button is associated with increased intra-abdominal pressure, and there may be an umbilical hernia or internal ascites.
Children don't need to pay too much attention to the bulge of the navel when they are born, which should be related to the length of the umbilical cord, but it is only a structural problem and does not affect health.
The main manifestation of an umbilical hernia is a bulging belly button. Because the umbilicus lacks fat, the skin of the abdominal wall is connected to the fascia and peritoneum, and the hernial sac in the abdomen protrudes along the membrane wall, causing the navel to grow outward, especially when the patient is standing or coughing.
It is found that there is an umbilical hernia that needs to be treated immediately, once the protruding part cannot return to the abdomen normally, it can easily lead to avascular necrosis of the intestinal tube, causing serious lesions such as intestinal obstruction and peritonitis.
Ascites is mostly related to liver disease, chronic hepatitis, liver cirrhosis, if the navel bulges, it is considered that it is ascites accumulation, and immediate treatment measures are required.
Changes in the shape of the belly button may be related to weakening bodily functions.
Under normal circumstances, people will be tall, short, fat and thin in their lives, and changes in the shape of the navel in this process belong to physiological structure problems and are normal phenomena.
If the navel is originally positive, but later appears to the left or right, it is necessary to consider whether there is a herniated lumbar disc, and the bone deviation leads to a change in the shape of the navel.
There are also people whose navel originally had an umbilical fossa, and then the lower abdomen became larger and caused the umbilical fossa to disappear, almost level with the umbilical eaves, this situation is not caused by an obese belly becoming larger, it may be long-term constipation, too much residue in the large intestine to "top" the navel out. Large belly caused by obesity usually deepens the umbilical fossa and rarely brings the entire navel out.
Fourth, protect the navel well, you should do this
In terms of physiological structure, the navel is a separate organ, which comes from the gift of the mother and is a physical trace left by the fetal period. Although the navel does not have a clear function for the body, if it is not well protected, it can affect health. Therefore, we usually have to control our hands and do not pick our navels casually to avoid accidental injuries. In addition, there are several aspects to pay attention to when protecting the navel.
1. Keep your navel warm.
The reason why we don't let us pick our belly button is also because we are afraid of cold wind entering and causing abdominal pain, but this is not enough, usually whether it is dressing or covering, do not expose the navel outside. Perhaps everyone has noticed that even in summer, as long as you cover your belly button when sleeping, it is not easy to catch a cold, otherwise it will make your immunity low and you will have colds, abdominal pain, and diarrhea.
The organ directly opposite the navel is the small intestine, which is the organ responsible for digestion and absorption, and the small intestine needs to maintain a certain temperature to function properly. The navel is not warm, the small intestine is not hot, digestive dysfunction can adversely affect the metabolism of the entire body.
2. Wash the navel to avoid strong irritation.
The dirt in the navel is unacceptable to many people, and if it is the outside part, it can be cleaned up. When washing the navel, it is best to use a cotton swab or other soft tools, dipped in water at a suitable temperature, and avoid rough washing and damage to the skin. There are more bacteria in the umbilical cord, which is easy to infect, and if there is a wound, it is necessary to apply external medicine under the guidance of a doctor.
In addition, it is prudent to wash the navel with a "disinfectant" liquid such as alcohol, which is easy to hurt the skin.
It is not recommended to wash the dirt near the navel folds, those substances have a certain effect on the skin of the navel and the warmth of the body. As the skin metabolizes, the dirt inside will come out on its own, and it is easy to be injured if it is forcibly cleaned.
3. The nerve at the edge of the navel is dense, protect it from injury.
In ancient medicine, the navel was called "Shenque" because doctors believed that it was a place where immortals lived, which played a vital role in human life and health.
Nowadays, some people wear crop tops or even umbilical nails for aesthetics, which may cause infection. People who do this may damage the body's immune system, causing problems in digestion, metabolism, and other aspects.
Conclusion of the article:
Everyone has a belly button, and it is in the middle of the human body, the first scar in life. The navel is not connected to any organ in the body and is a "dead end", but it has a certain effect on the organs in the abdomen. Due to the metabolism of the skin, there will often be some dirt in the navel, it is recommended to wash with warm water, do not pick by hand, here the skin is delicate and densely covered with all kinds of bacteria, once injured easy to cause infection.
Everyone's navel shape is not exactly the same, usually the navel is sunken, there is a umbilical fossa cornice, regardless of whether the shape of the navel is T-shaped, round, oval, or other irregular shape, it is healthy. Those cases where the navel bulge is severe and changes greatly may be related to physical health and require timely attention.
