There are many causes of dwarfism, and in order to treat it, we must find out the cause and make a correct diagnosis, and then consider how to treat it. In order to find out the cause of the disease, we must firstly take a medical history, ask about the physical condition, and conduct laboratory tests, and based on the detailed information and laboratory results, we will analyze and judge the cause of children’s dwarfism and finally determine the treatment plan. For children with short stature, first of all, we need to take an x-ray of the left wrist and metacarpal finger, i.e., a bone age film, in order to understand the bone age, determine the growth of the child’s bones, the degree of epiphyseal closure (if the epiphysis is closed, there is no possibility of treatment) and the growth potential, especially through a detailed assessment of the bone age and into the annual height prediction is very important, to know how high the child can grow without treatment, in order to know whether treatment is needed or to determine a more reasonable treatment plan (although the prediction The actual adult height is often lower than the predicted height, and the predicted height is not accurate when the difference between bone age and age is large, but at least we can know the approximate range and do comparison before and after treatment in order to evaluate the efficacy of treatment). Liver and kidney function, blood glucose, hepatitis B and half, blood and urine routine and thyroxine, and growth hormone stimulation test should also be done to know the growth hormone level, growth hormone is secreted at peak, and it is impossible to know whether the growth hormone is normal without stimulation test, and the standardized growth hormone stimulation test requires stimulation test of two drugs with a total of 8~9 time points (using retained needles, and not repeatedly sticking needles), as well as checking insulin-like growth factor 1 (IGF-1), and insulin-like growth factor binding protein (IGFBP-3). In girls, especially in immature girls, chromosomes are also checked to rule out “congenital ovarian hypoplasia (Turner syndrome)”, and in a very small number of boys, chromosomes may also be checked. A magnetic resonance imaging (MRI) or CT of the pituitary gland is usually required to rule out factors such as pituitary tumors that are not suitable for growth hormone application. Other special tests related to dwarfism can be arranged by the attending physician for your child’s specific condition.
