Patients who are short in stature and wish to increase their height with growth hormone injections. Regarding growth hormone injections in children, the following aspects need to be noted: Benefits: 1. Increase in height. As long as the bones are not closed, there is a chance of height growth; in those whose epiphyses are closed, the medication cannot further promote height increase; 2. The younger the age, the greater the potential for height growth and the better the medication may be; 3. Patients with growth hormone deficiency have a better treatment effect. Patients who are not growth hormone deficient, the treatment effect is poorer. However, as long as the drug dose is large enough, all can promote height increase. Precautions: 1. There are almost no side effects: occasional headache and joint pain; the drugs all need to be injected and there is no oral medication. 2. It does not increase the occurrence of new tumors. Tumors that are already there will grow as usual with or without the drug. For patients without tumors, the drug does not promote tumor occurrence; 3. The drug comes in various dosage forms. Powder: 20 yuan/unit, injected once a day; water: 40 yuan/unit, injected once a day; long-acting growth hormone: 80 yuan/unit, injected once in 7 days, which is more convenient to use; 4. Before using the drug, pay attention to the expensive cost; 5. Patients with growth hormone deficiency have good effect with the drug, promoting obvious increase in height; patients with no growth hormone deficiency have large differences in effect; some have good effect good, some have bad effect. For patients with Turner syndrome, GH treatment should be started as early as possible to increase height; 7. For patients who have developed puberty, Dafirac should be injected at the same time to temporarily stop puberty development and delay epiphyseal closure, so as to create conditions for height increase. 8. Measure height changes at intervals of 4-6 months. Before each visit to the clinic, the exact height and weight should be measured at the nurse’s station. 9. Be sure to match diet and exercise; supplement with adequate nutrition, run or jump rope every day; get enough sleep; also supplement with calcium and vitamin D.
