Every year, August 18 is the “Chinese Children’s Growth Day”. According to the survey, 90% of children with short stature have varying degrees of low self-esteem, depression, anorexia, social withdrawal and other psychological and behavioral abnormalities, and short stature will also bring problems to children’s future education, employment, communication and marriage. As a parent, you should pay attention to your child’s height, which means you should also pay attention to your child’s mental health. The long bones consist of the backbone and epiphysis, and there is a layer of cartilage between the backbone and epiphysis called epiphyseal cartilage (growth cartilage), also called epiphysis. The epiphyseal cartilage is stimulated by growth hormone to divide and proliferate, bone cells increase and ossify, and people grow taller. Therefore, two conditions are needed for a person to grow taller: the pituitary gland secretes sufficient growth hormone and the epiphysis is not closed. In two children with equal factors, from birth to epiphyseal closure, the age is growing and the bones are maturing. During this period, the amount of growth hormone secretion determines the height of these two children. Children who have sufficient secretion of growth hormone meet their body’s growth needs and grow taller, while children who have insufficient secretion will experience slow growth, which can eventually lead to short stature. The growth of height is not unlimited, the bones will continue to mature with age, and the epiphysis will close as the bones continue to mature, when the epiphysis closes, the body will stop growing, the height will finally be fixed, and the height gap will be formed.
