Talk about children with different heights in the morning and evening.

Hormone secretion is different. Some are early, some are late. Studies have shown that there are two stages in a person's life, namely, the rapid growth of the body and the significant changes in the proportion of various parts of the body. One is in the prenatal period and the first half year after birth, and the other is adolescence. The rapid growth and development of adolescence is called the phenomenon of rapid growth of adolescence.

In fact, this phenomenon begins before or at the same time as sexual maturity and ends six months to one year after sexual maturity. The rapid growth of men began at the age of 10.5- 14.5, peaked at the age of 14.5- 15.5, and then gradually slowed down. By the age of 18, the height has reached a fully developed level, and the weight, muscle strength, shoulder width and pelvic width have also increased.

For example, while women are experiencing external changes such as menstruation and secondary sexual characteristics, the reproductive organs gradually mature, pubic hair begins to appear in the vulva, vaginal secretions begin to increase, the uterus becomes larger, and follicles in the ovarian cortex begin to develop at different stages. Everything shows that the transition to sexual maturity has begun. Due to the physical and sexual development, it has a great influence on the psychological characteristics and social life of teenagers, which also produces a series of mental health problems.

Children grow up early, which may be caused by overnutrition, early development and precocious puberty Compared with children of the same sex and age, this kind of children with early puberty have obviously improved their growth speed and height, but their height potential is determined by their bone age. The rapid development of bones leads to the bone age being older than the actual age, which will lead to the premature closure of epiphysis, reduce the possibility and space for later growth, and easily lead to slow growth or stop growth.

Generally speaking, adolescence is the peak of children's growth. Girls are about 10- 14 years old and boys are about 12- 16 years old. If you slow down or stop growing ahead of time, you will miss the peak of growth and ignore the height of adults. At present, there are more and more phenomena of overnutrition, premature development, precocious puberty, so parents should keep their children in a nutritional balance and don't affect their growth because of premature development.

The reason why children "grow late" is not entirely because of late growth and development, but partly because of illness. Without timely treatment, they will not grow up healthily. If parents find that their children are slow-growing and short-stature, they should first rule out possible disease factors.
