1. Short height At birth, the height and weight are mostly normal and the limbs are well-proportioned. There is no obvious abnormality in the first few years after birth, but the growth slows down afterwards, especially in the years before 10–11 years old for boys and 9–10 years old for girls.
2. Delay in the appearance of secondary sexual characteristics The appearance of secondary sexual characteristics is delayed until the age of 16–18 for boys and 14–16 for girls.
3.Backward bone age Backward bone age is associated with delayed puberty initiation.
4.No deficiency of growth hormone Some children may have temporary or reversible deficiency.
5.Normal adult lifetime height After natural puberty, height growth is accelerated and sexual development is completed gradually. They can reach adult lifetime height around 20 years old and have normal secondary sexual characteristics and fertility.
Generally, no treatment is needed, and it is advisable to follow the growth rate and secondary sexual characteristics development, but in practice it is difficult to make decisions. In the current society, people attach great importance to height, and when children are lower than their peers in the same class or age, parents are under great pressure and cannot resist using growth hormone. The best way to deal with this situation is to monitor the child’s secondary sex characteristics, growth rate and bone age.
