Dwarfism is defined as a child’s height being less than 2 standard deviations from the average height of children of the same sex, age and race, with a growth rate of less than 7 cm/year for infants and toddlers under the age of 3, less than 4-5 cm/year for children between the ages of 3 and puberty, and less than 5.5-6.5 cm/year for adolescents. Simply put, if parents find that their child is the shortest child of the same sex in the class, or has an annual growth height of less than 4-5 cm, they should consider that their child may have a growth disorder. Some parents think that “children have early growth and late growth, 23 years old still leap a leap”, the child is short is not anxious, when found that the child really does not grow, and then go to the hospital is too late, the child may have epiphysis closed, lost the time to grow taller. The prerequisite for a child’s height growth is that the epiphysis is not closed. The earlier the epiphysis is treated, the more potential and space for growth, the more sensitive the child is to treatment, the better the growth effect, and the more desirable the final height in adulthood, so early treatment is effective. The younger the child is, the lighter the weight, the smaller the dose of medication, the less the cost, and the lower the cost of early intervention. There are two main causes of short stature in children, endocrine and non-endocrine. Endocrine causes include insufficient secretion of growth hormone, precocious puberty, hypothyroidism, Cushing’s syndrome, etc. Non-endocrine factors include family genetics and somatic, intrauterine growth retardation, malnutrition, chronic heart, liver and kidney diseases, chromosomal diseases such as congenital ovarian hypoplasia, skeletal diseases such as congenital chondrodysplasia, and psychological factors. Among them, short stature due to endocrine diseases such as growth hormone deficiency and hypothyroidism is the most common clinical condition. Children with short stature should be detected, diagnosed and treated as early as possible.
