Children with a baby face, look more well-behaved and cute, but if after the age of twelve or three, children are entering puberty, still a long face, it is slightly less mature. The most important thing is that some children not only have a baby face, height does not seem to be very long, compared to children of the same age to short on some, in school whether in line or sitting always in front, these children from the appearance and height to see than children of the same age a few years younger. For example, there is a news story about a young man in Hubei, Wu Kang, who is 22 years old but still has a baby face and is only 68 centimeters tall, looking like he is only 3 years old. As the best time for treatment was missed, even with the injection of growth hormone, her height could only grow by about 5 centimeters. This is a special case, but we should also be aware that if your child has a baby face and is shorter than other children of the same age, you should be alert to the possibility that your child has growth hormone deficiency. What is growth hormone deficiency? Growth hormone deficiency is a deficiency of growth hormone secreted by the pituitary gland due to various reasons. Growth hormone is a hormone that promotes the growth of the body. The main physiological role of growth hormone is to promote the synthesis of various tissues in the body, especially proteins, and stimulate the growth of cartilage in the bones and joints and epiphysis, thus making the body taller. If growth hormone is not secreted sufficiently, growth will be delayed and the body will grow shorter. This is medically known as “growth hormone deficiency”. Most children with this condition are born with normal growth, but they start to grow more slowly from the age of 2 or 3, and their height grows by 2 to 4 cm per year. With the growth of age, the height of these children is obviously lagging behind the normal healthy children of the same age and gender, and by the age of 8 or 9, they are even half a head shorter than the average child. In addition to delayed height development, their appearance appears younger than their age, with a baby face, slightly prominent forehead, high voice tone, good nutrition, slightly fatter, appearing to have a larger stomach, generally normal intelligence, some children are also relatively smart, and are among the top academic achievers in their classes. Some children can behave as sexually naive, some boys are 13 or 14 years old and still have small penises. For these children, parents should be alert and go to the hospital to find out if the child has a growth hormone deficiency. What should I do if I have a growth hormone deficiency? If growth hormone deficiency is diagnosed, it is recommended that your child be treated as soon as possible by giving him/her a genetically modified human growth hormone injection. The best age for treatment is around 5 years old because the earlier the treatment is given, the better the results and the less the cost. In addition, because growth hormone not only has the effect of promoting height growth, but also promotes the development and maturation of body organs, some children’s sexual development may be affected if growth hormone is deficient for a long time.
