How can you tell when your child has a growth delay? Many people simply do not know what it means to have height problems. If your child is half a head below the same age for a long time, or grows less than 5 cm per year, you should suspect growth retardation. Normal children grow at different rates at different times: generally 50 cm at full-term birth, less than 47 cm suggests intrauterine growth retardation; 25 cm growth in the first year after birth, 10 cm growth in the second year, the third year to the beginning of puberty growth rate of an average of 5-7 cm per year, puberty growth of 8-12 cm per year, lasting 2-3 years. Generally before the age of 3 years old growth is less than 7 cm per year, 3 years old to before puberty growth is less than 5 cm per year, after puberty growth is less than 6 cm per year, it is considered that the growth rate is slowed down, should be promptly consulted, early treatment. What is the reason for not growing? Growth hormone deficiency, hypothyroidism, precocious puberty, idiopathic dwarfism, systemic diseases, somatic growth and delayed puberty can all cause children not to grow. In the clinic, we met two siblings: the oldest boy was 10 years old and was measured at 1 meter 34, while the second girl was 9 years old and was measured at 1 meter 24, both of whom were diagnosed with idiopathic dwarfism. The children’s parents said that after school, the children were the shortest in the class. Idiopathic dwarfism is usually caused by genetic factors. Both parents are not tall, and the children are not tall. In addition, short stature with no obvious genetic characteristics and unknown causes is also considered idiopathic short stature. In the case of these two children, both parents are not tall, the father is 1m6m and the mother is 1m5m. It is obvious that the genetic factor is responsible for the short stature. We also saw a patient who looked 15 years old and was about 1 meter 4. But the actual age was 27 years old. And such an age is usually above 1.65 cm. This patient had another cause of short stature – growth hormone deficiency, or pituitary gland hypoplasia. Because her mother had a difficult delivery when she gave birth to her, usually a child born in a difficult birth is prone to pituitary hypoplasia and lack of growth hormone. In this case, growth hormone injections are usually given to make her taller. There is a big difference between treating short stature and not treating it. Some parents think that their children are short, it doesn’t matter, as long as they are healthy. So they don’t take it seriously. Slow growth is often one of the early signs of childhood diseases. For example: anemia, chronic kidney disease, digestive tract diseases, etc. Children who were sick a lot when they were young may also have an impact on their height development. And short stature, itself physical and mental development will be greatly affected. Most of them have psychological disorders such as low self-esteem, depression and other different Chengdu, and some children even don’t want to go to school because of their short stature. So if you compare the above data, once you find that your child is growing slowly, you should take your child to a professional endocrinology department for a detailed examination in time, including blood sampling to check growth hormone and X-ray to check bone age, because bone age is the most important indicator to predict growth space. For children with growth abnormalities, it is best to intervene before the age of 10. 80% of the lifetime height of the basic height before the age of 10, will leap during puberty development, accounting for 20% of the normal human puberty begins at the age of 10-12, regardless of gender, before puberty each year grows about 5 centimeters taller, and puberty grows about the same height, about 28 centimeters taller for men and 25 centimeters taller for girls. Girls are about 25 cm. Adolescence is like long jump, before the age of ten is to help run, help the longer the distance from the start to the end of the distance. Most children who do not grow can be cured Bone age is an important criterion to determine whether a child can grow again. As long as the bone age is not closed, there is room for growth. If the epiphysis is completely closed, the chances of growing taller are very low. To determine whether the bone age is closed, in addition to the use of x-ray, but also through the second characteristics of the person to determine the general situation, the following three conditions indicate that the epiphysis is basically closed: 1, girls have had their first menstruation for 3-4 years, and in the last 1-2 years no longer significantly taller; 2, boys 17 or 18 years old, the appearance of the second characteristics of the throat knot, beard, etc., the last 1-2 years also no longer grow; 3, the age of 18 around, the development is normal. “The most effective method in the clinic is to postpone puberty, control the development, and let the helper run longer, while increasing growth hormone to promote growth and also let the running speed be faster.” It is also better to use growth hormone as early as possible because the use of growth hormone is based on weight, and when the child is smaller and weighs less, the smaller the dose used and the less it costs. For children with normal height, there are also ways to help grow in size. Sleep before 10 pm The main regulating factors of growth in childhood are growth hormone and thyroid hormone secreted by the pituitary gland, which promote the proliferation and ossification of cartilage group cells, making the body’s long bones lengthen and prompting the body to grow taller. The pituitary gland secretes the hormone that promotes the growth of human body in the sleep state is the largest amount of secretion, three times more than the waking state, the peak of growth hormone secretion at 10 pm – 2 am, 35-45 minutes after sleep secretion increases, so it is best to go to bed before 9-10 pm, to ensure more than 9 hours of quality sleep every night. Outdoor exercise for 2 hours a day On the one hand, if children in the growth period exercise for more than 30 minutes, growth hormone will increase significantly, which in turn will promote bone growth. On the other hand, exercise itself will stretch the joint parts and promote the growth of cartilage tissue. In summer, there is enough light, and children who exercise outdoors also receive enough light, which is conducive to the synthesis of vitamin D in the body, so that the absorption of calcium can be guaranteed and the growth of bones will be fully comfortable.
