It is usually impossible to grow taller after epiphyseal closure. 1. During growth and development, epiphyseal chondrocytes divide, proliferate and ossify continuously, causing the bone to grow. After adulthood, the epiphyseal cartilage gradually ossifies, and eventually the epiphysis and epiphysis fuse together, leaving a trace called the epiphysis. Therefore, it is usually impossible to grow taller after epiphyseal closure. 2. Height growth is more obviously affected by genetics, endocrine secretion and intrauterine growth level. The genes of both parents determine the height of their offspring to a large extent. During the growth and development period, children need a lot of nutrients. Only with sufficient and appropriate nutrition, together with a suitable living environment, can the growth potential be fully realized. 3. Congenital or acquired diseases may hinder the growth and development of children, for example, endocrine diseases, congenital heart disease, etc. will cause growth retardation. Family and social environments also play an important role in height growth. More physical exercise and sun exposure can promote bone growth.
