Do children often get sick because of poor resistance?

Do children often get sick because of poor resistance?

Many young children seem to have colds and fevers throughout the year. They have to see a doctor several times a month. Parents can’t help but worry: “My child often gets sick, isn’t his resistance too poor?

Or am I not bringing children?

“Where does the resistance come from? The body must fight against the invasion of foreign pathogens by relying on a full range of immune defenses and functions, that is, white blood cells, antibodies, and skin and mucous membranes without gaps.

There are two main sources of immunity. One is that after the illness, the body produces special antibodies against the pathogen. When the potential pathogens invade again, the antibodies can be combined with white blood cells to kill the pathogen and avoid illness.

Obvious immunity, some can last for a long time (such as measles antibodies), and some are temporary (such as cold antibodies).

After vaccinating, the body will actively generate immunity after receiving stimulation. A small amount of immunity generally has ultimate effectiveness.

The second source of immunity is “passive”.

For example, newborns (babies within one month of birth) receive immunity from the mother to develop immunity; and after injection of immune serum proteins (ie, antibodies to a certain disease), it may cause short-term short-term conditions.Inhibitory effect.

Multinucleated white blood cells in the human body inherently have phage instincts. Lymphocytes can also produce various antibodies. Some antibodies have a considerable amount when the baby is born, but some do not reach the standard amount until the child is about 6 years old.

Newborns with increased resistance age may have some antibodies given by the mother to avoid certain diseases, but because the white blood cell function of the newborn is not good, and “complement” (stored in serum, can increase the antibodyEffect) is very low, can not cooperate with the role of antibodies to prevent the invasion of pathogens, so young children have very poor resistance.

Most people think that newborns have antibodies from their mothers, so they can stay ill. This is actually an incorrect concept.

Neonatal neonatal disease is because it is protected earlier and carefully, and there is less opportunity to contact the pathogen. Once attacked by the pathogen, not only will it get sick, but it will become very serious.

After 4 to 6 months, the antibodies that the baby receives from the mother will gradually disappear, and they will be able to make antibodies themselves.

White blood cells have also gradually matured, but because life contacts have gradually expanded, the chances of getting infected with pathogens are increasing, and they often get sick.

With the increase of age, due to the repeated stimulation of the disease, there are too many antibodies in the body and the resistance gradually increases. After the age of five or six, the number of illnesses will gradually decrease.

Frequent illnesses are not without resistance. Some young children repeatedly catch colds and fever, not because they have no resistance, but because they have more opportunities to contact the pathogen than others.

For example, in the air and crowded crowds, pathogens are everywhere, especially there are too many types of cold viruses. As long as you haven’t encountered them, you will have the chance to get sick.

Others: more brothers and sisters, and a small living space (family, neighbors, school) will also increase the chance of getting sick.

A simple example is that an adult who comes back from the outside and hugs a child before washing his hands is likely to pass the virus on his hands to the child.

Each child’s constitution and environment may be different. Some people have fewer illnesses, while others are.

But generally speaking, “minor illnesses continue and serious illnesses are not committed.” After growing up in surprise, parents will no longer invade in this area.

Most of the pediatrics who often run are children between the ages of half and four, and the number of illnesses will be reduced from about 10 times a year to once or twice a year, which is the case for most people.

Very few people with poor real resistance Children with really poor resistance are those with more severe, purulent infections that occur repeatedly on both ends for three days.Or often hospitalized and stunted, these diseases are caused by more “toxic” bacteria.

If young children often only have colds, fevers, and coughs, a few days will pass. This is caused by ordinary filter viruses, not immune deficiency problems.

How to prevent children from getting sick often Many parents think that letting children eat more supplements, supplements, healthy foods or vitamins can increase their resistance.

Some doctors and parents also think that they often fight “immune serum proteins” for young children, which can protect them from the cold.

In fact, these are not very useful, because vitamins have nothing to do with resistance.

Resistance comes from white blood cells and antibodies, and more young children do not have the problem of immune deficiency.

However, once you come into contact with an untouched pathogen and there is no antibody against it in the body, you will naturally be infected.

So the question is how much exposure to the pathogen.

However, if you maintain good nutrition, you can heal faster than others once you get sick.
