If a child is short in stature but has no developmental disorders after examination, it may be due to individual differences and slower development, and no special treatment is needed for the time being. If the child is too short in stature, or if there are symptoms of developmental delays such as speech and movement, the child should be treated at the hospital as soon as possible. In general, the earlier a child is treated for short stature due to developmental disorders, the more effective the treatment will be. The key hormones affecting growth and development are growth hormone and thyroid hormone, which can be treated accordingly according to typical clinical manifestations: 1. Dwarfism: It is related to growth hormone deficiency, and clinical treatment is mainly based on hormone supplementation and nutritional support, which is recommended to be treated before puberty, as much as possible before the age of 10. Treatment should be sought before complete bone development. The sign of stopping the growth of long bones is the fusion of the epiphysis with the backbone. The older the child is, the more likely the epiphysis will fuse and the less chance of continuing to develop. Children with dwarfism have a proportional body shape and normal intelligence, but there are symptoms such as short stature and low appetite. 2. Cretinism: associated with hypothyroidism, which can be caused by secondary factors such as congenital abnormal thyroid function or iodine deficiency. It is generally believed that active treatment before 3 months after birth can lead to better results in the later stages, and should not be delayed and should be treated as early as possible. If treated after the age of 1 year, although the child’s bones can still grow, the brain is poorly developed and the child’s intelligence is easily affected. Clinically, children not only have short stature, often accompanied by jaundice persistently does not subside, hypotonia, small eye fissure, nose collapse and other symptoms; 3. Other: short stature may also be associated with Turner syndrome, vitamin D deficiency rickets and congenital osteogenesis imperfecta and other diseases, it is difficult to confirm the diagnosis based on performance alone, should promptly seek medical examination and receive treatment as soon as possible after the discovery of disease factors.
