Many patients with short stature do not have any other uncomfortable symptoms except for their short height. Due to slow growth and development, they are usually rarely sick and most of them have normal intellectual development. In fact, as long as the height is lower than two standard deviations from the average height of the same region, race, age and sex or lower than the third percentile of the height curve of that population (in common parlance, it is the last three of a hundred such children lined up by large and small size) it is medically called dwarfism. Also growth less than 4-5 cm per year from age 3 to prepubertal and less than 5-6 cm per year during puberty is considered growth retardation. These children do not have hereditary diseases and various other diseases that affect growth, but when they reach adulthood is smaller than the average person’s height, or even larger than normal height, which will affect many problems of the child, such as future schooling, employment and marriage problems, which is a disease, and many parents think that the child may grow late and does not need treatment, and will be taller when the time comes, which is also a wrong idea. First of all, you need to know how old your child’s bone age is and whether he has room for late growth or not, so that you don’t delay and lose the best treatment time. If your child is shorter than the average child in the class, you must go to the hospital to check his bone age and make sure whether he has room for late growth.
