With the improvement of economic level and the pressure of employment and marriage, parents and teenagers have higher and higher demands on height. There is an article about the “fear of short age” mentioned in the discussion: with the improvement of living standards, accompanied by the arrival of the “fear of short age”, more and more parents and children are caught in the height of the anguish and confusion, followed by the “High obsession” and a series of height traps set and the staging of the tragedy of height, in order to increase a few centimeters, some people are quite risky, at the expense of huge sums of money for the “limb splints”, the results became a cripple. So, how does a child grow taller? Why there will be growth retardation or even short? How to determine if a child is stunted or short? When is the best time to treat growth retardation or shortness? What is the best time to treat growth retardation or short stature? How can children grow taller scientifically? These are the key questions that parents are concerned about. As we all know, growth and development is a characteristic of children, a person from fertilization to adulthood is a very complex process, affecting many factors, regulated by their own endocrine system, which growth hormone, thyroxine, sex hormones at different stages of the independent or synergistic promotion of children’s growth. Human growth is actually the growth of human bones, there is a kind of bone in the human body is hollow round tube, known as tubular bone, at the ends of these bones, there is a part of cartilage called “ossification center”, cartilage cells in the growth hormone under the action of continuous splitting, calcification of the hard bone, the growth of bones, that is, the human body’s height increase. The growth of bones, i.e., the increase in height of the human body, is realized. However, the human body can not grow taller indefinitely, to a certain age, all the cartilage cells will be calcified and no longer split, known as “epiphyseal healing”, at this time, the human body will not grow taller. Therefore, for children with growth retardation, it is necessary to take “bone age film” to know the age of bone development. Most children are able to grow along the normal trajectory under the regulation of their own endocrine system, while a small number of children, due to the influence of disease, heredity, the surrounding environment and other factors, there is a growth retardation or even shortness, so what kind of situation belongs to the growth retardation and shortness? Infancy is the fastest growing period, the average height of normal infants at birth 50 cm, the first year can grow 20 cm, the second year, the third year of about 8 ~ 10 cm; children’s period of average annual growth of about 5 cm; to puberty, is the growth of another peak period of time, the girl puberty is generally 10 ~ 14 years old, can grow 10 ~ 15 cm; the boy puberty later than the female, generally 12 ~ 16 years old, can grow 20 ~ 25 cm. Can grow 20~25 centimeters. If a child’s annual growth rate is <7 cm within 3 years of age, <5 cm in childhood, and <6 cm in puberty, growth retardation is indicated. If your child is in the bottom 1 or 2 in a class of about 50 students, your child may have dwarfism. There are many causes of growth retardation or dwarfism, about 300 kinds of causes, which can be divided into two categories: growth hormone deficiency and non-growth hormone deficiency, the latter includes malnutrition, micronutrient deficiency, familial heredity, chronic diseases, congenital hereditary metabolic diseases, and endocrine disorders such as delayed hypothyroidism, congenital ovarian dysplasia, and precocious puberty, etc. Different causes of different treatments, and only when we find the cause and treat it appropriately, we will be able to find the right treatment. Only by finding the cause of the disease and carrying out symptomatic treatment, it is possible to grow taller. For those with short stature, the younger the age at which the correct treatment is started, the better the result will be. After puberty, the epiphyseal growth plate ages, the growth space becomes smaller, and the effect of increasing height decreases significantly. If the epiphysis has completely closed, any medicine is of no help. If the epiphysis has completely closed, any drug will not help. If a child with growth hormone deficiency is treated with growth hormone replacement therapy from the age of 4, it can be expected to reach a completely normal adult lifelong height. There is no panacea for short stature, and research has proven that no single drug can make all short stature grow taller. For example, the internationally recognized growth-promoting drug, growth hormone, is only suitable for children with growth hormone deficiency and some non-growth hormone deficient children. Therefore, growth retardation should be found in the pediatric endocrine clinic of the regular hospital, early identification of the cause of the disease, do not wait and see, and do not blindly use the so-called height enhancement products. So, how to let the child grow taller scientifically? First of all, to balanced nutrition, that is, daily intake of a certain amount of protein (eggs, meat, fish, dairy), carbohydrates (noodles, rice, etc.), vitamins and minerals-rich vegetables and fruits, etc., do not favoritism, picky eaters, otherwise it can lead to a lack of micronutrients, such as zinc, iron, calcium, etc., which directly affects the growth and development of children. Various foods, to milk, sardines, spinach, carrots, oranges is the most rich in a variety of nutrients, try to let the child every day intake of some of these foods. Secondly, develop good eating habits. Chew and swallow slowly when eating, and avoid strenuous activities for 30 minutes after meals to help better digestion and absorption. Third, make sure you exercise properly. Exercise helps children grow taller, studies show that: jumping rope, swimming, playing basketball or volleyball, jumping sports, cycling and other sports half an hour later, the body's growth hormone secretion increased significantly, bone growth fast. While long-distance running, weight lifting, high-intensity sports training, etc. but hinder the growth of children. Fourth, to ensure sufficient, high-quality sleep is another important way to promote children's growth. Because the secretion of growth hormone begins to increase after 1 hour of sleep, and continues at a higher level. In the clinic often see children in adolescence, due to the heavy curriculum after junior high school, sleep less than 8 hours, resulting in a slow growth rate, affecting the child's lifelong high. Fifth, you should keep a happy mood. Family discord, poor relations with classmates, teacher discrimination and other negative factors often put children in a state of long-term emotional depression, affecting the secretion of growth hormone, which can lead to "psychogenic dwarfism". Sixth, early diagnosis and treatment. If you find that your child's growth is slow, you should consult a doctor in time to find out the cause of the disease and treat it as soon as possible. If you can pay attention to the above points, scientific growth is not a distant dream.
