Spring is here, and many parents expect their children to grow taller as quickly as the crops do during this time of growth. Indeed, height is a major issue in a child’s life. In China, most children get regular medical checkups from birth to infancy to monitor whether their growth and development are normal, and first-time parents are also very concerned about their children’s changes. However, after the age of 2 to 3 years, parents’ attention begins to shift to their intellectual development and to their common illnesses, distracting them from their child’s growth. Few parents in our clinic can tell the change in their child’s height after 2 years of age, and only parents of children with severe short stature can recall that their child could wear the same size pants for 2 to 3 years. How much do children actually grow taller each year? Are their height changes normal? In the face of the child’s growth, many parents did not pay attention to these changes, is “seedlings do not worry about growth”, “children early growth, late growth will always grow” and so on the proverbial parents of children to relax their vigilance. 1, “there are seedlings do not worry about growth” mistaken child growth in my outpatient clinic patients, an 18-year-old girl height of only 131cm, parents in the year after year of waiting for the child did not “late growth” up, because the girl is 23 years old has not menstruation. If parents can pay attention to the fact that the child’s growth is obviously lower than that of children of the same age at the age of 4~5, if parents can find that the child’s annual height growth is less than 4cm, and if parents can pay attention to the fact that the girl has no sign of breast development when she should be developing, then the tumor may have been detected earlier, and the child may be able to grow more quickly. If the parents could have noticed that their child’s height was growing less than 4cm per year, and if they had paid attention to her when she had no signs of breast development when she was supposed to be growing, then the tumor might have been detected and treated earlier. The child’s parents had also consulted their pediatrician and took a lot of calcium and zinc supplements. In fact, calcium and zinc deficiency will affect the growth, but there are many, many related factors that determine the problems in growth, just like building a building, cement and sand are important, but due to other reasons for slowing down the speed of building, supplementing with more cement, sand and other building materials will not help. 2, the child 2 years old height does not reach the normal standard need to be vigilant Factors affecting the growth and development of children can be broadly divided into two categories of intrinsic and extrinsic factors. Heredity is a very important intrinsic factor. Pediatric growth and development characteristics, potential, etc. by the parents’ race, stature, external physical characteristics of the influence of hereditary diseases, whether chromosomal aberrations or metabolic defects have an impact on growth and development. The secretory function of the endocrine glands plays an important role in growth, and disorders of the corresponding endocrine function due to any cause can result in growth and developmental abnormalities. The role of the thyroid, hypothalamus, pituitary, and gonads is particularly important. Hypothyroidism that develops within 2 years of age, especially in the newborn period, is often associated with mental retardation and short stature. However, hypothyroidism that develops after 2 years of age is often associated with normal mental ability, and some children may not have typical symptoms of hypothyroidism, but may show slow growth, constipation, and fatigue easily. Patients with tumors of the hypothalamus or pituitary gland or developmental anomalies usually do not have intellectual problems, but only growth retardation. As the child gets older, he or she lags behind normal children in height. Gonadal endocrine secretion accelerates growth and promotes epiphyseal closure. Abnormalities in fetal development also contribute to height and developmental problems after birth. The birth of premature, full-term small samples of children’s height lagging behind, if the age of 2 years old can not catch up to the normal child’s height, or family genetic height better children barely catch up to the same age of normal children’s height low line, belong to the scope of abnormality. 3, those years pants are not short children should seek early medical treatment Gender also has an impact on the speed of growth and development and characteristics, showing gender differences between men and women, the average height and weight of girls before puberty is smaller than boys of the same age, but the pubertal development of girls is 2 years earlier than that of boys, this stage of the growth of the girls will be accelerated, and boys in the subsequent 2 to 3 years of pubertal development, to complete the growth of the The growth spurt is completed by the onset of puberty in the following 2-3 years. In our outpatient clinic, the children are often high school students or college students, when the child only grows 2~3cm in 1~2 years, and the child’s height is very unsatisfactory, the parents will be anxious, especially at this time, the boys will pay great attention to their own height, but the bone age is usually suggestive of the closure of the closed or close to the closure of the bone age, when the results of the children informed of the children, in the face of the parents and the children of the disappointment of the eyes, as the doctor’s is very regrettable. It is a pity to see the disappointed eyes of parents and children when they are informed of the results, especially for those children who could have improved their lifelong height if they had come to the clinic earlier! Growth and development, like other abilities of a child, are not subject to endless changes, and sometimes it is true that “after this village, there is no such store”. Therefore, for children who are short at birth, for children who have short height in their family, for children who have high family height but their height never reaches the curve of the genetically predicted target height, for children who have early sexual development, for children who can’t wear their pants shorter than a couple of years, for children who are always sitting at the first row in the class and whose growth rate is less than 4cm per year, both girls and boys should seek medical advice from a pediatric endocrinologist as soon as possible. Consultation, pediatric endocrinologist can help you understand whether the child’s growth is normal. 4, children eat more health products, can cause early closure of bone age In my patients, a 143cm girl in the third year of college, because of the obstacles to find a job, came to the clinic, the bone age has been closed, the parents’ height are very good, the child’s genetic target height should be able to reach 164cm. after the history of questioning, the exclusion of related diseases, the mother said that the child was always like a cold and fever, so she had given the child a lot of supplements, there is a good chance that the child will be able to reach 164cm. The child has taken a lot of supplements to increase height, increase appetite, improve immunity, these supplements may be the cause of the child’s growth acceleration at the same time to promote the advancement of bone age, resulting in the early closure of bone age, resulting in the child’s lifelong height becomes shorter reasons. The mother said thousands of dollars of health care products have never begrudged, hoping that the child can grow stronger good intentions, but ultimately harmed the child. Human growth and development is a huge and complex process, and deviations in growth patterns are non-specific but are quite important indicators of serious diseases. Many diseases such as intracranial, adrenal, ovarian tumors or chromosomal diseases, some genetic metabolic diseases, etc., will show abnormal growth and development in the early stage: too fast or too slow growth, obesity, precocious puberty and other phenomena, and if these early signs are ignored, the treatment is often delayed, resulting in irreversible damage to the child.
