Usually growth hormone is helpful in promoting human height, but it is not suitable for all children, especially for people with closed epiphyses. The age, bone age, height status, endocrine status and hormone tolerance of the subject should be examined to determine whether growth hormone is suitable for use. As long as one of the indicators does not meet the requirements, it should not be used, otherwise it will have a great negative impact and may be counterproductive and accelerate the end of the skeletal growth period. Usually growth hormone is indicated for sick children with hypothalamic dysfunction and low growth hormone production power, using artificial injections to alleviate this condition. If the patient does have dwarfism in early adolescence, growth hormone may be used. If the dwarfism is related to genetics and bone condition, then more growth hormone will not help. It is important to ensure that children get enough sleep, rich meals, and proper physical exercise on a daily basis, so that the normal functioning of the endocrine system and the normal absorption of the digestive system can be ensured, and that the growth hormone normally produced in the body is sufficient to meet the growth needs. In conclusion, before injecting growth hormone, it is necessary to examine whether the system is resistant to the drug, whether it can be absorbed well, and whether there are no other organ diseases before it can be used safely and effectively.
