Nowadays, the number of children asking for height increase is increasing. People are now asking for human height increase not only because of the pursuit of beauty, but also because of the many reasons that have led to the phenomenon of short stature in many children and adolescents, and people have to carry out rapid human height increase for their children for the sake of their future. It is relevant to pay attention to the causes of a child’s height increase, however, what causes the phenomenon of stunted growth in many children and adolescents is a problem that has a stronger relevance for the whole society. After years of research, the main causes of growth retardation in children and adolescents are the following: 1. Genetic factors, the characteristics of children’s growth and development, physique, potential, limits, etc. are governed by the genetic factors of their parents. Race, family genetic information on the next generation is far-reaching, for example, skin, hair color, facial features, etc.; hereditary diseases either chromosomal aberrations or metabolic defects have a significant impact on growth and development. 2, gender, the growth and development of boys and girls are different, in general, the average height and weight of girls are lower than that of boys. Girls’ puberty is roughly two years earlier than boys’, and during this beginning time, girls’ growth and development is faster, but boys’ pubertal development lasts longer than boys’, so boys’ final height still exceeds that of girls. Therefore, when analyzing the growth and development, boys and girls should be studied separately. 3, endocrine growth hormone, human growth is mainly regulated by a variety of hormones, especially growth hormone and sex hormones are particularly important. When growth hormone is lacking, the symptoms of short stature will appear; sex hormone can make the bones fuse earlier and affect the growth and development, so the adolescents with early puberty will affect the final height growth. 4, the situation of the pregnant mother, the growth and development of the fetus in the mother’s body is affected by a variety of factors such as the growth environment, emotions, nutrition and diseases of the pregnant mother. If the mother is malnourished, it can cause fetal miscarriage, premature birth, fetal physical and brain development retardation, etc. If the mother is ill in the early stages of pregnancy, it can directly lead to fetal malformation.
