After a series of tests, children diagnosed with growth hormone deficiency are finally being treated with recombinant human growth hormone (rhGH). The growth-promoting effects of rhGH are obvious, but parents and children should work together to maximize the growth-promoting effects of rhGH. First of all, parents should learn more about the growth pattern of young children, so that early detection and treatment will not delay the best treatment time for children. Most of them are already mature and their epiphyses have basically healed, missing the opportunity for human intervention. In addition, it is important to learn more about recombinant human growth hormone (rhGH), including injection techniques, storage methods, and basic nursing knowledge. It is not uncommon to see cases of poor outcomes due to improper injection methods or incorrect storage of medications in outpatient clinics. There are also a few cases in which parents’ lack of knowledge about injections and care has caused their children to be overwhelmed by the psychological shadow of “talking about needles”. Secondly, it is important to strengthen the two communication (parent and child, parent and doctor) and to monitor the child’s height and adverse side effects. The child should be promptly guided to avoid low self-esteem and depression due to height problems. In addition, communication with the doctor should be strengthened, and questions about the child’s life should be organized for follow-up consultation. You should follow up on what you do not understand, so that misunderstandings or knowledge will not cause a discount in the efficacy of recombinant human growth hormone. At least every month, the child should be measured for height. When measuring height, pay attention to the fixed time, have the child stand upright against the wall, feet together, heels against the wall, chest up, use a book or cardboard with one side stuck on the head and the other side parallel to the wall, mark and measure the specific value. Ask your child about any discomfort after the rhGH injection, including headache, dizziness, nausea, changes in vision and visual field, leg pain and swelling, etc., and relay the information to the doctor in time for the follow-up visit. Last but not least, the most important thing is to adjust the living habits to match the growth promotion effect of growth hormone, which is summarized in four phrases: increase exercise, regulate emotions, sleep well, and enhance nutrition with a balanced diet. Specifically, children are required to make efforts in the following areas: 1. Increase exercise: It is important to insist on running, jumping rope, swimming and other aerobic exercises, and you can also participate in some dance, gymnastics and other professional training. But do not overexert yourself, so as not to affect the normal diet and sleep. 2, regulate emotions: parents should channel the children’s negative emotions, do not because of their height problems for a long time in a depressed, depressed state of mind, encourage the children to be confident and generous, believe in themselves and the efforts of the doctor, will grow taller quickly. 3, quality sleep: after going to sleep, when the growth hormone secretion peak is the best time for children to grow. The subcutaneous injection of rhGH every night before bedtime is to imitate the secretion pattern of growth hormone under the physiological condition to achieve the therapeutic effect of growth promotion. Therefore, we should encourage children to improve their efficiency during the day and strive to go to bed early at night, so that they can develop the good habit of going to bed early and waking up early, so that they can grow happily in their sleep with the effect of rhGH. 4.Balanced diet and enhanced nutrition. After the use of rhGH, most children have to go through a rapid growth period, so it is necessary to provide enough raw materials to make the bones grow faster and stronger, otherwise it will affect the growth rate or appear “tofu dregs” project. Therefore, it is important for children to consume more protein, mineral salts (zinc, iron, etc.) and various vitamins, such as milk, eggs and high-quality protein – fish, chicken, tofu, etc. At the same time, it is also necessary to control the intake of calories and try to avoid fried and deep-fried foods, such as KFC, McDonald’s and other fast food, so as not to have the undesirable consequence of gaining weight before growing. In short, we cannot rely on the power of rhGH alone, but must work together with doctors, parents and children from the above aspects, and persistently insist. This is the only way to make the children grow faster and taller.
