Growth hormone is a commonly used treatment for short children with growth hormone deficiency, but it does not allow for unlimited growth in height, and the degree of growth is related to factors such as the age at which the treatment is given. Among children with short stature, some children with growth hormone deficiency have growth disorders due to partial or complete lack of growth hormone synthesis and secretion by the pituitary gland, etc. A common treatment for these children is recombinant human growth hormone replacement therapy. The use of this drug does not result in unlimited height growth, and its therapeutic effect is related to the age at which it is used and the duration of its use. If the treatment is given at a younger age, it is usually more effective, and the effect is obvious in the first year, with a height increase of more than 10~12cm, after which the growth rate may decrease. If necessary, it is recommended to consult a specialist.
