The clinical determination of the effectiveness of growth hormone is an increase in annual growth rate of more than 2 cm/year after treatment compared to pre-treatment. Growth hormone can be tried for 3 months, and if it grows more than 2 cm in 3 months, then it is effective. If the growth is less than 2 centimeters, you need to analyze the factors that affect the effectiveness of the treatment together with your treating doctor. Some parents often ask why their child has not grown after using growth hormone for a month or two. It is important to remind parents not to enter the misconception that their children will grow taller quickly if they apply growth hormone therapy. First of all, from the perspective of children’s growth and development, height growth is a relatively slow process, and it is impossible to achieve an “instant” effect after using medicine. Secondly, the criteria for determining the effectiveness of clinical growth hormone treatment for children with short stature is that the annual growth rate of a child is considered effective if it increases by more than 2 cm compared to that before treatment. Generally, 3 months of growth hormone treatment is an observation course, and relatively obvious treatment effects can be seen in 3 months. It is normal for a child to grow more than 2 cm in three months of treatment. It is clinically proven that growth hormone is used in the treatment of children with short stature, and the treatment can effectively improve the growth rate of the affected children, thus improving their final height.
