Why do children often get sick? In addition to external causes, it is mainly due to the child’s own physiological and pathological characteristics. So what are the physiological and pathological characteristics of children? A, physiological characteristics 1, the internal organs are delicate, the shape of the gas is not full; vigorous, rapid development The internal organs are delicate, refers to the internal organs are delicate and tender, the shape of the gas is not full refers to a variety of physiological functions have not been sound. Among them, the lungs, spleen and kidneys are more prominent. On the one hand, this is due to the fact that the lungs, spleen and kidneys are all intact and not yet strong after birth. On the other hand, the biggest difference between children and adults is that children are in constant growth and development, so children not only need to maintain normal physiological activities as adults, but also must meet the special needs of growth and development. Therefore, children have higher requirements for the functional status of kidney qi generation, spleen qi transportation and lung qi propagation. Therefore, relative to the growth and developmental needs of the pediatric population, there is often a deficiency in the function of the kidney, spleen and lung, showing that the lung is delicate, the spleen is often deficient and the kidney is often deficient. The lungs of children are delicate, deficient resistance to external functions, cold and temperature can not be self-regulation, the Ming Dynasty Wan Mizai pointed out that “delicate lungs are vulnerable to injury” that “the cold and heat of heaven and earth are also injured, the lungs are the first to be affected by the sensation” lungs for the clear deficiency of the organs, both easy to be evil, but also not resistant to cold and heat, so children are prone to Therefore, children are prone to colds, coughs, pneumonia and other respiratory diseases. The spleen is the main organ of transportation and transformation, and is the source of biochemistry of qi and blood, providing the material basis for the rapid growth of the child. The functional state of the spleen and stomach is often incompatible with the rapid growth and development of children, which means that the spleen and stomach are heavily burdened with function. Once the diet is improper or improperly supplemented, the spleen and stomach can cause disorders of transportation and transformation, resulting in food accumulation, vomiting, diarrhea, stagnation, anorexia, noma and other diseases that can seriously affect the growth and development of children. The incidence is second only to lung-related diseases in pediatrics. The kidney is often deficient in children, which means that they are not full of qi and blood, and the kidney is not solid. The kidneys collect the essence and are the master of the bones. This function of the kidney is even more important for children whose bodies have not yet grown and whose physiological functions have not yet matured. It is directly related to the function and shape of the bones, brain, hair, ears and teeth of children, and to the maturation of growth and sexual function. Pediatric kidney often deficient, performance of kidney essence is not full, infants and young children can not be self-control or self-control ability is weak. As they grow older, not only can they control their bowel movements, but their teeth become longer at the age of six until they reach adulthood. As a result, we can see many clinical diseases of kidney essence loss and skeletal changes, such as pediatric rickets, hydrocephalus, enuresis, edema, etc. The heart and liver of children are also not yet full, and their functions are not yet healthy. They are prone to fright and poor restraint in thinking and behavior; the liver is the main drainage and wind master, so children with unrealized liver qi and unhealthy tendon strength and tendons are active and prone to fright and twitching. The child’s internal organs are delicate, the form of Qi is not yet full, which means that the child is in the period of growth and development, the form of its internal organs has not yet matured, and various physiological functions are not yet sound. Therefore, the resistance to various diseases and evil attacks and the ability to tolerate drug attacks are low. 2, vigorous, rapid development The body of the child, both in terms of morphological structure and physiological functions, is constantly and rapidly developing and growing. For example, the length, chest circumference and head circumference of children increase with age, and the thinking, language and movement abilities of children increase rapidly with age. The younger the child is, the more obvious this vigorous vitality is. Second, the pathological characteristics 1, the onset of easy, rapid transmission of children’s internal organs are delicate, the form of gas is not yet full, the younger the age, the more prominent the performance of the delicate internal organs. The younger the child is, the more prominent the manifestation of delicate internal organs is. The easy onset of disease in children is highlighted in lung, spleen, kidney diseases and infectious diseases. At the same time, children are not yet full of vital energy, so their ability to resist evil is weak, and they easily feel all kinds of seasonal evil and epidemic poison. Evil from the nose, the lung health attack, forming measles, mumps, chicken pox and other infectious diseases; evil from the mouth, the spleen and stomach by evil, resulting in dysentery, cholera, hepatitis and other infectious diseases. Once infectious diseases occur, they are easy to infect each other among children, causing epidemics. These characteristics of children’s bodies make them susceptible to disease, and once the onset of disease changes rapidly, such as pediatric pneumonia can even cause complications such as heart failure if not treated in a timely manner. At the same time, the child’s body is vigorous, the qi of the internal organs is clear, with the allocation of the response to a variety of treatment; and the child has fewer chronic illnesses, the condition is relatively simple. Therefore, although pediatric diseases are characterized by easy onset and rapid transmission, generally speaking, the speed of improvement is faster than that of adults, and the possibility of cure is greater than that of adults. For example, most of the illnesses such as pediatric colds, coughs, diarrhea, etc. have fast onset and fast recovery, while the illnesses such as pediatric asthma, epilepsy and yinshui have a relatively good prognosis compared to adults, despite their lingering condition. The cause of the disease is characterized by 1, external factors such as external wind, cold, heat, humidity, dryness, fire. 2, the milk food factor The milk food of the child is valuable in order, sometimes, and in a way. Due to improper parental feeding, lack of milk at birth, or failure to add complementary food on schedule, or arbitrarily indulge the child’s preferences, unbalanced diet, can make the child’s spleen is not full of spleen, transport and transformation of the loss of health, resulting in spleen and stomach disease evidence. Often, because children are naive, they cannot control and regulate their own diet, which can easily lead to picky eating, partial eating, too much cold eating hurts Yang, too much hot and spicy eating hurts Yin, too much fat and sweet and greasy eating hurts the spleen, etc. Children are prone to uneven hunger and satiety, and too little milk food intake can lead to insufficient biochemistry of Qi and blood, while too much milk food can lead to damage to the spleen and stomach. Unclean diet is also a common cause of pediatric morbidity. 3.Congenital factors Congenital factors, that is, fetal factors, refers to the pathogenic factors that have acted on the fetus before the birth of the child. Genetic etiology is the main cause of pediatric congenital factors, the parents’ genetic defects can lead to congenital malformations, physical defects or metabolic abnormalities in children. 4, emotional factors The perspective of children’s perception of the external environment is different from that of adults, so the emotional factors that lead to disease in children are somewhat different from those of adults. The most common emotional and psychological injury of children is panic. When a child sees a foreign object or suddenly hears a foreign sound, it will easily lead to panic and sadness, night crying, palpitations, frightening and twitching; long time of not wanting and lacking care will easily lead to worries, which will damage the heart and spleen and lead to anorexia, vomiting, abdominal pain, loneliness and depression; parents’ over-indulgence in their children makes children’s psychological ability to bear poorly, or the burden of learning is too heavy, and parents’ expectations are too high, which are easy to The child has no or too high expectations. 5, accidental factors Children do not have or lack the ability to take care of themselves, do not have or lack the ability to judge the safety of the surrounding environment or dangerous conditions, and therefore vulnerable to accidental injury. For example: accidental contact with boiling water and open fire burns, bruises, poisoning by accidental ingestion, asphyxiation by inadvertent inhalation of foreign bodies, etc. 6, other factors Modern clinical, environmental and food pollution or pesticides, hormones, has become a common concern for the current pathogenic factors. Radioactive substance injury, including injury to fetus and children, has attracted widespread attention.
