Many parents use drugs indiscriminately because their children are short, and many parents expect their children may have “late growth” and blindly wait, resulting in many children losing the best period of height increase. Here, we remind parents that they should grasp the best treatment period for their children’s dwarfism in time. Children with dwarfism are generally defined as those whose height is less than 2 standard deviations from the average height of the same sex and age, and whose annual growth rate is less than 4-5cm. There are many causes of short stature, which can be broadly divided into two categories: “disease-related short stature” and “non-disease related short stature”. The common causes of diseased short stature include growth hormone deficiency, hypothyroidism, congenital ovarian insufficiency, precocious puberty, certain metabolic diseases, certain chronic diseases and malnutrition. Non-disease dwarfism includes familial dwarfism, idiopathic dwarfism, prematurity, low birth weight, small for gestational age, and somatic growth delay. Generally, once the epiphysis closes after puberty, the growth of height will stop and the height will be fixed. In fact, children with short stature can be treated, parents must pay attention to it. First of all, if you find out that your child is significantly lower than other children of the same sex and age, you should go to a hospital that has the conditions for examination and find a pediatrician for detailed examination, such as: cranial radiograph, bone age radiograph, growth hormone and post-stimulation test level measurement, thyroid function measurement, chromosome examination, etc. After identifying the cause of dwarfism and treating it correctly according to its cause, never seek medical advice or use drugs indiscriminately. The younger the child is, the better the treatment effect. Don’t miss the best treatment period for your child.
