How to promote the secondary development of bones, first of all, we need to clarify the reasons for the delayed development of bones or affect the development. First, if it is due to congenital growth hormone deficiency or metabolic disorders, you should go to the hospital for growth hormone testing, and after diagnosis, you can treat the symptoms, and the most commonly used method in the clinic is to inject growth hormone, which promotes the secondary development of bones. Secondly, if the disease is caused by congenital chromosomal abnormality or other defective diseases, so far there is no clear treatment or medicine for this kind of genetic disease. Thirdly, if the growth and development is delayed due to calcium deficiency, the patient should go to the hospital as soon as possible to have his blood calcium tested, and if it is confirmed that the patient is suffering from hypocalcemia, timely calcium supplementation can often be used to promote the secondary development of the skeleton.
