Questions about your child s growth and development. 20

SY is something that must be abstained. The main bone of the kidney (Western medicine talks about the kidney controlling the filtration and reabsorption of calcium ions), SY will indeed affect height development, you can let him quit color, SY sequelae** go to see, or you go to see, put down the content of the boutique stickers inside, communicate with him calmly, and talk to him about the harm of SY (affecting height development, leading to memory loss, causing impotence in the future, early xie, and will also lead to prostate xianitis, hundreds of thousands of people have been destroyed by SY in the abstinence of color! The foreskin is too long, and if it can be turned out during the erection, it is not too long.

It is better not to have a circumcision. JJ size problem, erection of 13 cm is normal, and it will grow by the age of 18, but if you don't quit SY it won't grow anymore! Best wishes.

1) Heredity. A child's growth and development is related to the influence of genetic factors in both parents.

2) Nutrition. Nutritional factors are an important influencing factor for children's normal growth and development, and supplementing adequate nutrition can help promote children's normal growth and development, and when children's nutritional intake is insufficient, it often leads to adverse effects on their body shape and body system.

3) Environment. Children's living environment, environmental sanitation conditions and other factors are important factors affecting their normal growth and development, and being in a healthy environment such as fresh air, abundant light and clean water sources is more conducive to children's healthy growth.

4) Exercise. Moderate exercise during children's growth and development is more conducive to the secretion of growth hormone in their bodies, thereby promoting their normal growth and development.

5) Family. A good family atmosphere is of great significance for cultivating children's character and character, and for children's intellectual development.

6) Disease. When a child suffers from an acute illness, the child's weight is easily reduced, and the sharp point is that when the child suffers from certain chronic diseases, the child's height and weight will be adversely affected.

The growth and development of children from the beginning of the fertilized egg to the birth of the child has been affected by both internal and external factors, and the two interact with each other. So, what are the specific factors that affect a child's growth and development?

1) Heredity.

The character of parents can be passed on to their children. The length of the parent's stature also affects the next generation. The incidence of mental retardation in the children of consanguineous marriage is higher than that of the general population, indicating that heredity is closely related to the growth and development of children.

2) Nutrition.

The nutritional situation of pregnant women during pregnancy is related to the development of the fetus. Undernutrition in pregnant women will cause the fetus to stunt growth in the womb, and overnutrition will lead to macrosomia, making delivery difficult. Long-term nutritional insufficiency after birth not only affects the growth rate of weight and height, but also adversely affects the development of intelligence.

However, excessive nutrition can cause obesity and have adverse effects on the body and mind. In addition, various trace elements such as zinc, iron, iodine, etc. are also closely related to children's physical and neuromental development.

What are the factors that affect the growth and development of children's spine?

(3) Disease

Diseases during pregnancy can affect the development of the fetus and even cause malformations. Perinatal birth trauma, hypoxia, asphyxia, intracranial hemorrhage and other diseases can affect the development of children's intelligence. Acute illness after birth will cause significant weight loss, and chronic illness will have an impact on weight and height.

Some endocrine disorders are short stature. Traumatic brain injuries and infectious diseases of the nervous system sometimes leave with varying degrees of mental retardation.

(4) Medications

During pregnancy (especially in the first 3 months), the use of drugs by pregnant women has a greater impact on the fetus. Attention should also be paid to postnatal medication, such as streptomycin, gentamicin, and kanamycin given in larger doses or for a longer period of time, which can cause hearing impairment in children. People who take adrenocorticosteroids for a long time have a slow rate of height gain.

Cytotoxic drugs, antithyroid drugs, can directly or indirectly affect growth.

(5) Education

Early education has a positive effect on the psychological development of infants and young children. Mother-infant contact in the first hour of life is closely related to the formation of the baby's personality and positive emotions in the future. Parents are their children's first teachers and should play an exemplary role in daily life.

In the process of educating only children, it is necessary to prevent weaknesses such as coquettishness, arrogance, and poor self-care ability. In addition, through proper education, it is possible to improve the intelligence level of people with mild mental retardation.

(6) Environment

Physical exercise with full use of sunlight, fresh air, water, and a reasonable living system can promote physical and mental development. There should be some places in the family for children to play games, do homework or put their own toys and books. Avoid environmental noise, lead pollution, passive smoking, and parental behavior; All these factors have adverse effects on children's physical and mental development.

Heredity determines the potential for children's growth and development, which is regulated by environmental factors from the beginning of the fertilized egg, and the level of growth and development shows the individual's growth and development pattern under the combined action of heredity and environment.

1. Genetic factors.

The genes contained in the chromosomes of cells are the material basis for determining heredity. The genetic factors of both paternal and maternal parents determine the "track" of children's growth and development, or the characteristics, potentials, and tendencies of growth and development. Ethnicity, family genetic information has a profound impact, such as **, hair color, facial features, body shape, sexual maturity sooner or later, nutrient requirements, susceptibility to infectious diseases, etc.

In abnormal cases, inherited metabolic defects, endocrine disorders, chromosomal malformations, etc., which seriously affect growth, are more directly related to heredity.

Second, environmental factors.

a) Nutrition. Children's growth and development, including intrauterine fetal growth and development, requires adequate nutrient supply. When the ratio of nutrients is provided in the right proportion, coupled with the right living environment, the growth potential can be maximized.

Fetuses with intrauterine malnutrition not only lag in physical growth, but also affect brain development in severe cases; Postnatal malnutrition, especially severe malnutrition in the first and second years, can affect weight, height and mental development, and make the body's immune, endocrine, neuromodulation and other functions low.

b) Disease. The obstruction effect of the disease on growth and development is very obvious. Acute infection often leads to weight loss; Long-term chronic diseases affect the development of weight and height; Endocrine disorders often cause skeletal growth and neurologic retardation; Growth retardation in congenital disorders, such as congenital heart disease.

3) Mother's situation.

The development of the fetus in the womb is affected by various factors such as the living environment, nutrition, emotion, and disease of the pregnant mother. Maternal viral infection in the first trimester of pregnancy can lead to congenital malformations of the fetus; Severe malnutrition during pregnancy can cause miscarriage, preterm birth, and stunted fetal growth and brain growth; The first trimester of pregnancy is affected by certain medications, x-ray exposure, environmental toxicants, and trauma, which can be accompanied by a combination of stunted fetal development.

4) Living environment.
