If you go to the endocrinology department of the Union Hospital because you are short, you will need to undergo these tests: 1. We will compare your height with the standard height of your peers of the same sex through a chart. 2. Bone age film: To determine if your bones have closed. If it is not closed, it suggests that there is still a chance to increase height with medication. If it is already closed, there is no chance to grow. 3, anterior pituitary function check: first of all, whether there is a lack of growth hormone, you need to do hypoglycemic growth hormone excitation test or levodopa growth hormone excitation test. There are also indicators to check IGF-1. In addition, thyroid function, sex hormone levels, cortisol, etc. need to be checked. If necessary, there is also a need to check the head pituitary MRI. 4. Because malnutrition and other medical diseases can also lead to lack of height growth, liver and kidney functions should be routinely checked. Because bone lesions can lead to short stature, the development of the spinal bones needs to be routinely checked. 5. After clear diagnosis, you can consider whether to carry out growth hormone treatment. In general, if the patient is growth hormone deficient, the treatment effect is better after using growth hormone, and the height increase is about 6-12cm per year. If there is no growth hormone deficiency and there are no other diseases, then the patient is a “normal person” and may not need treatment at all. If there is a strong desire to increase height, then growth hormone therapy can be considered on an experimental basis after full understanding of the efficacy and adverse effects of growth hormone, full communication with the doctor, patient and parents, and after signing an informed consent form. Use the drug for 3-6 months to observe the effect of growth hormone. 6. For patients who already have pubertal development, it may not be enough to use growth hormone alone, because the epiphysis will soon close on and there is limited time for height growth. In this case, if you want to get a better height, you may need to use GnRHa at the same time as growth hormone injection to inhibit the patient’s pubertal development and delay the time of epiphysis closure to provide more sufficient time for the patient’s height growth. Of course, medical costs will increase by 2,000 RMB per month when treatment is carried out in this way. 7.Usually, it takes 3-6 days for all the above tests to be done in the outpatient clinic of Concordia Hospital, and then wait 3-6 days for the full results to come out. Follow-up visits to the hospital may be required at intervals of 1-3 months throughout the treatment process.
