1.Familial short stature (i.e. parents with short height). 2. Intrauterine growth retardation at birth (full-term small-like children), premature babies are smaller than normal newborns, and 10%-15% of them cannot catch up to the normal height curve after 2 years of age. 3.The growth of height is less than 5 cm per year before puberty. 4.Shorter height compared with children of the same age. 5.Sexual development is too early or too late. 6.Obese children. 7.History of breech birth, difficult birth, birth asphyxia, traumatic brain injury, etc. and combined with slow growth. 8.Children who have taken or have taken for a long time height-enhancing drugs, immune-enhancing drugs, glucocorticoids, kidney-supplementing herbs, combined with rapid sexual development and premature growth spurt, etc. 9.Children with hypothyroidism. Some children with congenital hypothyroidism develop before the age of 2 years, which can cause mental retardation if left untreated. However, the onset after 2 years of age usually shows symptoms such as growth disorders, constipation, anemia, low activity, and low appetite. Many parents are not aware that their children’s slow growth is also a disease, and they either leave their children’s height to time or spend a lot of money to supplement their children’s nutrition and use height-enhancing devices, not knowing that these blind measures often delay treatment and even backfire. If abnormalities are found, consult a pediatric endocrinologist in time to determine the indications and treat them in time, and never have the mentality of waiting, delaying your child’s growth for various reasons and causing lifelong regrets.
