First, how does the human body grow taller? The human body height mainly depends on the length of the lower limb bones, which have epiphyseal cartilage at both ends, and the bones gradually grow longer as the cartilage cells continue to divide, proliferate and ossify. Until adulthood, epiphyseal cartilage cells continue to divide and proliferate, and the bones grow gradually; if the epiphyseal cartilage is completely replaced by bone tissue and the epiphysis is completely fused with the backbone, the bones no longer grow and the child’s body no longer increases in height. The younger the child is, the greater the potential for epiphyseal cartilage to proliferate and the greater the time and space for the child to grow taller. In most cases, chondrocytes stop dividing and growth stops by the age of 18 for boys and 16 for girls. After the epiphysis has healed and growth has stopped, no drugs will work to increase height. Second, how to help children grow taller? Height is determined by congenital genetic factors and acquired environmental factors. Genetic factors determine the possible range of height, while environmental factors influence the genetic potential and determine the speed of growth and the degree of attainment. Genetic factors have a large influence on height, about 70%. And the influence of many environmental factors such as nutrition, disease, maternal and pregnancy conditions, and living conditions, is about 30%. Short stature can be the result of a particular disease or multiple factors. If you want your child to reach his full growth potential and grow taller and healthier, you need to pay attention to the following aspects Provide adequate nutrition: Ensure adequate, reasonable and balanced nutrition during the growth period, regular health care from infancy, and scientific feeding for the growth and development characteristics of children at all stages. Protein is an important nutrient to ensure height growth, and milk is the best food to promote growth, containing both high protein and high calcium, as well as other protein-rich foods, appropriate amounts of fat, minerals, vitamins, especially calcium and zinc. To make your child grow taller, you also need to develop good eating habits from an early age to ensure that your child gets enough nutrients. Ensure enough sleep: We all know that children will grow taller if the level of growth hormone in the human body is high. The secretion of growth hormone has a certain regularity, and the amount of growth hormone released will increase with longer sleep time. Generally speaking, children aged 3 to 6 years old should have 10 to 12 hours a day, elementary school students 10 hours, junior high school students 9 to 10 hours, and high school students 8 to 9 hours. Active physical exercise: physical exercise can improve the body’s blood circulation, promote the body’s absorption of nutrients and enhance the growth of bone cells. According to the age and physical condition of the child to develop exercise plans, infants and toddlers can do active or passive gymnastics; school-age children can do some exercises that help height growth, more walking, more running, more jumping, but also pay attention to do stretching exercises, such as bar. Exercise stimulates the division and proliferation of epiphyseal chondrocytes in long bones, thus growing taller. In addition, exercise promotes increased secretion of growth hormone. Minimize diseases and maintain good mood: Provide a good living environment for children, minimize diseases and injuries, and promptly find and eliminate physical and psychological obstacles brought about by adverse stimuli to children to ensure their healthy growth. Third, what are the common causes of childhood dwarfism? There are many causes of childhood dwarfism, generally divided into two types: growth hormone deficiency and non-growth hormone deficiency. Growth hormone deficiency in children is caused by structural abnormalities of the hypothalamus-pituitary gland or abnormalities in the function of secreting growth hormone, such as hypothalamic-pituitary dysplasia, traumatic brain injury, tumor or radiation injury causing a decrease in pituitary gland function and a decrease in growth hormone secretion, resulting in slow growth of height and leading to short stature. Such patients can only take growth hormone supplementation from outside the body. Non-growth hormone deficiency dwarfism is common in familial and somatic dwarfism: such as hereditary dwarfism, somatic growth retardation, intrauterine fetal growth retardation, abnormal pregnancy of the mother, causing the child to be born with height and weight significantly smaller than normal children, for these children should be given a good acquired environment to promote the genetic potential. There are also diseases such as congenital ovarian hypoplasia, hypothyroidism, and abnormal cartilage development in girls that cause short stature. Short stature that excludes all known diseases is called idiopathic short stature, which also accounts for a significant proportion of all short stature. 4. How to determine short stature? Short stature is defined as a child whose height is below the third percentile of the growth curve of a normal healthy child of the same age and sex or below two standard deviations. Growth below 5 cm; puberty below 6 cm suggests slow growth. v. Why are children with precocious puberty short in stature? From the long-term development of human beings, youthful development is improving year by year, and the whole normal human development is the same as the height, which is improving year by year. In the last century, the average age of female menarche was 15 or 16 years old, but now the average age of menarche is about 12 years old, so the early development of puberty is the trend of the whole human youth development, probably related to the nutritional status, the temperature of the atmosphere, the whole national system, and the stimulation of many adult information to children. Pubertal development is defined as precocious puberty in girls before the age of 8 and in boys before the age of 10. Precocious puberty can also cause dwarfism. Children with precocious puberty tend to have earlier bone age than their actual age, and when sexual development signs appear, their height is often taller than normal children of the same age, which means that they are 10 years old at this time, but their bone age may have already advanced to 13 years old. Therefore, his final height is short. How to do about short stature? A reasonable diagnosis and treatment: short stature may be caused by a certain disease or a variety of factors. If parents find that their child is short in stature, they should go to a regular hospital to see a specialist because the diagnosis of such diseases, such as hormone level testing, chromosome testing and imaging of the pituitary gland, often requires more complete medical equipment and conditions. The diagnosis can be confirmed only after the doctor takes a medical history, conducts a thorough physical examination, and performs the necessary laboratory tests and comprehensive analysis. Effective medications and a series of interventions are scientifically applied to the cause of the disease in order to achieve the desired results. Don’t use drugs blindly, because some drugs can enhance protein synthesis and promote growth in the short term, but the danger is that the epiphysis will close early and affect the final height. Second, we should grasp the best time for treatment: human body growth should seize the period from 2 years old to puberty to give full play to the growth-promoting effect of growth hormone, and if a child is found to be short, he or she should be treated as early as possible. The younger the treatment age for children with pathological dwarfism, the better the efficacy, and the less medication is used, and the difference between the final height and that of the same age is not too big.
