There are many different manifestations of pediatric growth retardation, including mental retardation, language retardation, physical retardation, etc. The causes are also varied, including growth variation, genetic factors, malnutrition and certain diseases, etc., but the treatment of different causes is also different. The main reason is related to congenital genetic factors or fetal dysplasia, but the growth rate is basically normal, which is characterized by physical growth retardation and requires adequate and balanced nutrition and good dietary habits. In addition, some hereditary diseases and endocrine diseases can also cause growth retardation, such as chromosomal abnormalities such as Down’s syndrome, skeletal system diseases such as chondromalacia, chronic malnutrition, growth hormone deficiency and endocrine diseases of hypothyroidism, etc. In this case, it is necessary to consult a hospital for examination to clarify the cause and treat the symptoms. Therefore, if the relevant laboratory tests are abnormal, a detailed consultation with a pediatrician is required to confirm whether further tests and treatment are needed.
