Nowadays, there are more cases where children are not as tall as they should be because they missed the optimal growth intervention period. There was a girl who had her first menstruation at the age of 10 weeks and only officially got her period six months later, because the person was very thin and the parents didn’t care that their daughter had developed. Later, the girl’s height stayed at 1.46 meters and did not grow much. Intervention in such a case would not be effective. Medically speaking, to grow taller, three ages are important before the child reaches puberty! The first, at 4 weeks of age. The main 4 weeks of age is to rule out any congenital diseases that affect the child’s growth so that they can be treated as early as possible. There is a golden dividing line for determining children’s short stature, and that is at the age of 4. Around the age of 4, growth hormone and thyroxine have been basically formed in the human body, and diet and sleep habits are gradually formed, and these conditions play a decisive role in future growth and development. The second time, when boys are eight or nine years old and girls are seven or eight years old. This is to determine whether the child’s growth and development are normal, whether the biological age matches the life age, and whether there are signs of precocious sexual maturity before sexual development. The third time, at the age of 12 or 13. The main purpose is to see the child’s growth and development and also to make a prediction of the final height. The younger the child is, the more active the proliferation and differentiation of the cartilaginous layer of the epiphysis, and the greater the potential and space for growth. Parents should not wait until the child is in the later stages of development, such as 15-18 years old, to treat the child, when the epiphysis is close to closing and the growth potential is small. A balanced diet is most important for children to grow taller. In addition to genetics and environmental factors, diet, sleep and exercise are all very important. It is best to intervene early if the child shows some tendency of precocious puberty. In the clinic also encountered such a case, the father is 1.75 meters tall and the mother is 1.60 meters tall, but the son is 15 weeks old and is only 1.56 meters tall, when she treated the child for 9 months, the boy grew 7 cm taller. Therefore, parents must usually pay attention to their children’s growth and intervene early if there is a problem. If the bone age reaches 16 weeks old, there is basically nothing more that can be done medically. Doctors suggest that parents should not blindly give their children health care products and foods such as royal jelly, pollen, etc., to ensure that children eat three balanced meals is the right way. Secondly, in the daily diet, parents should control the food basket, avoid letting children eat chicken, duck, goose neck, cow whip, cow testicles and other animal sex organs should not eat too much. In addition, out-of-season vegetables and fruits should also be avoided for children to eat.
