The hazards of growth hormone injections mainly include the following aspects: First, local reactions: Generally, on the first day of injection, skin redness and swelling will appear, and even local pain or fever may occur, which can subside in a week. Second, antibody production: The production of antibodies is mainly related to growth hormone, which can affect the effect of growth hormone. Third, subclinical hypothyroidism: After subclinical hypothyroidism, facial swelling, or weakness and drowsiness may occur, which requires replacement therapy with eugenol until the symptoms disappear completely. Fourth, slippage or necrosis of the femoral head: Because promoting the growth of the skeletal line in children is to play growth hormone, in order to accelerate growth and muscle increase, so it will lead to slippage or aseptic necrosis of the femoral head in the hip joint. Fifth, idiopathic elevated intracranial pressure: growth hormone can cause water and sodium retention. Sixth, tumor: growth hormone can mainly promote mitosis of cells. Seventh, accelerated pubertal development: Growth hormone will accelerate growth after playing more, so it will lead to accelerated pubertal development. At present, because of the rapid development of genetic engineering, the side effects of growth hormone are relatively small. There must be indications for growth hormone, one is that the bone line is not closed, and the other is that it is indeed two standard deviations shorter than the same age.
