Growth hormone is a growth protein synthesized by the cells of the anterior pituitary gland, which can effectively promote the growth of articular cartilage and epiphyseal cartilage in children. Injections should not be given to patients with specific organic pathologies, as they may cause irreversible damage to the body, such as inducing coronary heart disease, peripheral neurological disorders, and musculoskeletal and other conditions. If for the hormone deficiency and lead to slow growth or underdevelopment of children, in the doctor’s advice can be used, the quality of the current domestic production technology is still relatively over the quality, the harm caused by less. Within one week after the injection, there may be local redness and swelling around the injection, which can be subsided, and may cause nipple edema. If children with high blood pressure are injected, intracranial hypertension may occur; if there is a long-term calcium deficiency, it may cause epiphyseal slippage or necrosis; there are also rare groups of people who do not have significant curative effects after injection due to the presence of special antibodies in their bodies. In short, the growth hormone injected through normal channels is safe and effective, but it also has certain rejection effects, for example, some children are allergic to the hormone, and if they consume an excessive amount of it, it is very likely that it will cause gigantism, and the development of secondary sexual characteristics is not sound.
